Description

RELATED APPLICATIONS

The disclosure is related to U.S. patent application Ser. Nos. 11/751,928 and 11/751,931, both filed on May 22, 2007.

TECHNICAL FIELD

The disclosure relates generally to aircraft production. More particularly the disclosure relates to manufacturing methods and apparatus which utilize composite modules to fabricate components and structures.

BACKGROUND

Some components of modern commercial aircraft, such as the aircraft fuselage skin, for example, may be fabricated using advanced fiber placement (AFP) machines. The baseline process of using AFP machines for aircraft fabrication processes may require a high capital investment in the purchase of many AFP machines, tooling, factory floor space and personnel. At current AFP lay-down rates (e.g., about 15 lbs/hr), a large number of AFP machines may be required to place the quantity of material which is needed to support the acceptable production rates of commercial aircraft.

Therefore, a manufacturing method is needed which may have a relatively high rate capacity and lower capital investment requirements and may not require skilled operators and programmers for implementation.

SUMMARY

The disclosure is generally directed to a composite manufacturing method. An illustrative embodiment of the method includes providing a plurality of composite modules; inspecting the composite modules; providing a curing tool; and placing the composite modules on the curing tool.

The method provides a high manufacturing rate and requires only lower capital investment. Moreover, the manufacturing method may not require skilled operators and programmers for implementation.

DETAILED DESCRIPTION

Referring initially to FIGS. 1-3 of the drawings, a manufacturing system which is suitable for implementation of an illustrative embodiment of the modular composite manufacturing method is generally indicated by reference numeral 1. The manufacturing system 1 is shown in top view in FIG. 1 and in perspective view in FIG. 2. The modular composite manufacturing method may utilize simple, right-sized equipment to enable lay down of composite materials in parallel processes rather than in series as part of the fabrication of composite aircraft fuselages or other parts. The use of a parallel process approach to the automated lamination of aircraft fuselage skin modules or other parts may dramatically reduce the flow time required to fabricate a single part. This may reduce the capital investment, factory floor space and support staff required to fabricate composite aircraft fuselage skins or other parts. Furthermore, the method may be used in the fabrication of flat-layup composite parts such as aircraft fuselage skins, for example and without limitation or contoured-layup composite parts such as aircraft wing skins and stabilizers for example and without limitation. The method may be used to fabricate panels, quarter sections, half fuselage sections, more than half fuselage sections or full barrel sections.

As shown in FIGS. 1 and 2, the manufacturing system 1 may include one or multiple flat tape layup machines (FTLMs) 2 to facilitate fabrication of flat-layup composite parts such as aircraft fuselage skins, for example and without limitation. Additionally or alternatively, the manufacturing system 1 may include one or multiple contour type layup machines (CTLMs) (not shown) to facilitate fabrication of contoured-layup composite parts such as aircraft wing skin, nose skin and/or tail skin, for example and without limitation. The FTLM and CTLM may have a design which is known to those skilled in the art. Although an exemplary structure and method of operation for the FTLM 2 will be hereinafter described, it will be recognized and understood that the same method of operation may be utilized with respect to one or more CTLMs in addition to or instead of the FTLMs 2.

Each FTLM 2 may include a pair of generally elongated, parallel, spaced-apart frame track rails 3. A carriage frame 4 may span and be adapted to bi-directionally traverse the frame track rails 3. The carriage frame 4 may include a pair of generally elongated, parallel, spaced-apart carriage frame members 5. The carriage frame members 5 may be oriented in generally perpendicular relationship with respect to the frame track rails 3.

A cutting carriage 6 may be adapted to bi-directionally traverse the carriage frame members 5 of the carriage frame 4. A carriage motor (not shown) may engage the cutting carriage 6 to facilitate movement of the cutting carriage 6 on the carriage frame 4. A cutting device 7 may be provided on the cutting carriage 6. In some embodiments, the cutting device 7 may be an ultrasonic knife, although alternative cutting implements which are known by those skilled in the art and suitable for the purpose may be used.

A transfer platform rotation track 10, which may be circular or annular, may be provided between the frame track rails 3 and beneath the carriage frame 4. A transfer platform 14 may be removably provided on the transfer platform rotation track 10. The transfer platform 14 may have a generally square shape. The corner portions 14a of the transfer platform 14 may slidably or rotatably engage the transfer platform rotation track 10 according to the knowledge of those skilled in the art such as through rollers (not shown), for example and without limitation. As will be hereinafter described, a carrier sheet 16 may be placed on the transfer platform 14. A composite module 18 may be placed on the carrier sheet 16. The transfer platform 14 may be rotated on the transfer platform rotation track 10, the carriage frame 4 may be moved along the frame track rails 3 and the cutting carriage 6 may be moved along the carriage frame members 5 of the carriage frame 4 to facilitate cutting of the composite module 18 along a selected axis or axes by operation of the cutting device 7.

As shown in FIGS. 1-3, the manufacturing system 1 may further include a SADL (Semi-Automated Doubler Locator) machine 22. The SADL machine 22 may include a pedestal 23 which may be rendered portable by multiple pedestal wheels 24. A module forming platform 25 may be provided on the pedestal 23. The module forming platform 25 may be adapted to receive and support a carrier sheet 16 on which is laid a composite module 18 for purposes which will be hereinafter described.

As further shown in FIGS. 1-3, the manufacturing system 1 may further include a pick and place machine 30. As shown in FIGS. 1 and 2, the pick and place machine 30 may be situated generally adjacent to the SADL machine 22. As further shown in FIG. 1, in some embodiments an SADL machine 22 may be provided at or generally adjacent to respective ends of the pick and place machine 30. The pick and place machine 30 may include a gantry 31 having a pair of generally elongated, parallel, spaced-apart rails 32. The rails 32 of the gantry 31 may each be supported by multiple, spaced-apart rail supports 33 as shown in FIG. 3. At least one placement head carriage 36 may span and slidably engage the rails 32 of the gantry 31. Each placement head carriage 36 may be adapted for bi-directional travel on the rails 32, as indicated by the double-headed arrow 8 in FIG. 1. A carriage motor (not shown) may engage each placement head carriage 36 to facilitate movement of the placement head carriage 36 on the rails 32.

As shown in FIGS. 2 and 3, a module placement head 40 may be suspended from each placement head carriage 36. The module placement head 40 may include a head shaft 41 and a generally curved or arcuate module engaging member 42. The head shaft 41 of the module placement head 40 may be attached to the placement head carriage 36 using any suitable technique which is known to those skilled in the art. In some embodiments, at least one head mount flange 37 extends from the placement head carriage 36. At least one module attachment bracket 44 extends from the head shaft 41. The module attachment bracket 44 may be connected to the at least one head mount flange 37 via a head fastening member 38.

As further shown in FIGS. 2 and 3, the module engaging member 42 of the module placement head 40 may include a generally convex module forming surface 43. A scanner 49 of an inspection scanner system 46 may be adapted to traverse the module forming surface 43 of the module engaging member 42. The scanner 49 may be attached to the module engaging member 42 according to the knowledge of those skilled in the art for the purpose. In some embodiments, a generally elongated, curved scanner slot 47 may be provided in the module engaging member 42 generally adjacent to and along the module forming surface 43. A scanner bracket 48 may engage the scanner slot 47 for traversing the scanner slot 47. The scanner 49 may be provided on the scanner bracket 48. A scanner motor (not shown) may engage the scanner bracket 48 to facilitate selective movement of the scanner bracket 48 in the scanner slot 47 and the scanner 49 along and adjacent to the module forming surface 43 of the module engaging member 42. An inspection analysis and control system (not shown) may be connected to the scanner motor (not shown) and the scanner 49 to facilitate the scanning motion of the scanner 49 and retrieve and analyze images received from the scanner 49.

The manufacturing system 1 may further include a cure tool, mandrel or mold 54. The cure tool 54 may be an OML (Outer Mold Line) or an IML (Inner Mold Line) cure tool, for example and without limitation. As shown in FIGS. 1, 2 and 3, the cure tool 54 may be situated generally adjacent to the SADL machine 22 and between the rails 32 of the pick and place machine 30. As shown in FIG. 3, in some embodiments the cure tool 54 may include a tool base 55 and generally parallel, spaced-apart tool sides 56 which extend from the tool base 55. A generally curved or semicircular module placement surface 57 may be provided in the tool base 55 and the tool sides 56 and may extend along the length of the cure tool 54. However, it will be recognized and understood that the cure tool 54 (such as in the case of IML cure tools, for example) need not necessarily have a full cylindrical or half-cylindrical cross-section as shown with respect to the module placement surface 57 of the cure tool 54. Under circumstances in which it is desired to utilize the manufacturing method on quarter panels, for example and without limitation, cure tools 54 having both an OML and an IML configuration could be used. Furthermore, the cure tool 54 may be configured as a wing or stabilizer mold, tool, cure tool or in any configuration depending on the part which is to be fabricated.

In typical implementation of the modular composite manufacturing method, the method may be used to fabricate an aircraft fuselage skin 60 (FIG. 1) using the multiple composite modules 18. Depending on the application and the part which is to be fabricated, each module 18 may include any combination of unidirectional carbon fiber prepreg; carbon fiber prepreg fabric; fiberglass; KEVLAR® [poly (p-phenyleneterephtalamide); or other materials. Each module 18 may have at least one ply. A carrier sheet 16, on which may be laid a composite module 18, may initially be placed on a transfer platform 14. The transfer platform 14 may be placed on the annular transfer platform rotation track 10 of a FTLM 2. The cutting device 7 on the cutting carriage 6 may be operated to trim or cut the composite module 18 to the desired dimensions and shape. During the trimming, cutting or moduleting operation, the composite module 18 may be positioned at selected orientations with respect to the cutting device 7 by movement of the cutting carriage 6 along the carriage frame members 5 of the carriage frame 4; movement of the carriage frame 4 along the frame track rails 3; and/or rotation of the transfer platform 14 on the transfer platform rotation track 10. Each FTLM 2 may facilitate high-speed moduleting of the composite modules 18 which are to form the aircraft fuselage skin 60 using net trim technology.

After trimming or cutting of the composite module 18 the transfer platform 14, on which is laid the carrier sheet 16 and the trimmed or cut composite module 18, may be removed from the transfer platform rotation track 10. The transfer platform 14 may be transported from the FTLM 2 to one of the SADL machines 22. Removal of the transfer platform 14 from the transfer platform rotation rack 10 and/or transportation of the transfer platform 14 may be automated or manual. At the SADL machine 22, the carrier sheet 16 may be removed from the transfer platform 14 and placed on the module forming platform 25 of the SADL machine 22. The carrier sheet 16 may be provided with multiple tooling/index openings (not shown) which may be indexed to the SADL machine 22 to facilitate proper positioning and placement of the carrier sheet 16 on the module forming platform 25.

The placement head carriage 36 may next be operated to slide along the rails 32 on the gantry 31 of the pick and place machine 30 to position the module engaging member 42 of the module placement head 40 directly over the composite module 18. The module forming platform 25 of the SADL machine 22 may then be raised against the module forming surface 43 of the module engaging member 42 to form or contour the flat composite module 18 to the generally convex contour of the module forming surface 43, as indicated in phantom in FIG. 3, through a module-compaction process. Forming and contouring of the module 18 to the module forming surface 43 of the module engaging member 42 may be automated. Additional composite modules 18 may be transported from the FTLM machine 2 to the module forming platform 25 of the SADL machine 22 and formed to the module forming surface 43 of the module engaging member 42 in a laminated or multi-ply manner as needed to achieve a desired thickness of the aircraft fuselage skin 60 (FIG. 1). Accordingly, successive composite modules 18 may be placed on each other to form a laminated module 18 having multiple plies. Depending on the application, the module placement head 40 may place continuous fiber plies or continuous fabric plies in conjunction with knitted plies of the composite modules 18. In some applications, adjacent modules 18 may be coupled to each other according to the knowledge of those skilled in the art. It will be recognized and understood that the composite modules 18 need not always be formed onto the module forming surface 43 of the module engaging member 42 on the module placement head 40. In the case of an IML curing tool 54, the modules 18 may be formed directly onto the curing tool 54 or onto other skin plies using the SADL machine 22.

After the desired number of composite modules 18 has been staged on the module placement head 40 of the pick and place machine 30, the scanner 49 of the inspection scanner system 46 may be operated to traverse the module forming surface 43 of the module engaging member 43 for the purpose of inspecting the composite modules 18. Defective composite modules 18 may be removed from the module placement head 40 and replaced with non-defective composite modules 18. Inspection of the modules 18 on the module placement head 40 may be an automated process.

The placement head carriage 36 of the pick and place machine 30 may then be operated to traverse the rails 32 on the gantry 31 of the pick and place machine 30 and facilitate precision placement of the stacked, laminated, compressed and inspected composite modules 18 in the desired location on the module placement surface 57 (FIG. 3) of the cure tool 54. Additional stacked, laminated and compressed modules 18 may be formed in similar manner and placed in the desired locations on the module placement surface 57 to form the aircraft fuselage skin 60. Module edges 19 of adjacent modules 18 may be ramped and overlapped with a scarf (not shown) or ramped splice joint (not shown) until the aircraft fuselage skin 60 is completely laid up.

Referring next to the flow diagram 300 in FIG. 4, an illustrative embodiment of a modular composite manufacturing method is summarized. The method may be used to fabricate an aircraft fuselage skin having a desired thickness, for example and without limitation. In block 302, a composite module may be laid up. The module may be an aircraft fuselage skin module which may be used to fabricate a structure such as an aircraft fuselage skin, for example and without limitation, and may be laid up using an FTLM (Flat Tape Layup Machine), for example and without limitation. Additionally or alternatively, the module may be used to fabricate a structure such as an aircraft wing skin, nose skin or tail skin, for example and without limitation, in which case the module may be laid up using a CTLM (contour tape layup machine). In block 304, the module may be transferred to an SADL (Semi-Automated Doubler Locator) machine. In block 306, the module may be formed to the contour of an aircraft fuselage skin or other structure. In block 308, the steps carried out in blocks 302, 304 and 306 may be repeated to form a desired thickness of the aircraft fuselage skin or other structure. In block 310, the modules may be inspected. In block 312, the stacked or laminated modules may be stacked onto a curing tool. The curing tool may be an OML (Outer Mold Line) or IML (Inner Mold Line) curing tool, for example and without limitation. In block 314, the steps carried out in blocks 302, 304, 306, 308, 310 and 312 may be repeated as necessary to completely lay up the aircraft fuselage skin or other structure.
