The present disclosure relates to a method and system for a fastener-receiving insert system for use with a composite panel.
Composite panels, such as honeycomb-cored sheets, often cannot have mechanical fasteners directly affixed thereto. In some instances, if such a composite panel requires a mechanical fastener to be affixed thereto, a fastener-receiving insert can first be installed in and secured to the composite panel, and the mechanical fastener then engaged with the insert. In this manner, the mechanical fastener can be used with the installed insert to secure the composite panel to other structures.
Such fastener-receiving inserts are typically installed in insert-receiving orifices in the composite panels. The inserts are generally installed so as to be as close to flush or coplanar with the outer surface of the composite panel as possible, in order to provide optimal interaction with the mechanical fastener and the other structures, and structural integrity of the assembled end product. Such inserts are often installed in composite panels using adhesive material (e.g., a special purpose two-part potting compound) in a multi-step process.
Thus, there is a need for a fastener-receiving insert and method for installing the same in a composite panel that reduces installation time, reduces equipment requirement, reduces labor, is easily automated and minimizes wastage of adhesive materials.
The above and other needs are met by aspects of the present disclosure which, in one aspect, provides a fastener-receiving insert system. The fastener-receiving insert system includes a fastener-receiving insert having a proximal end and a distal end and at least one adhesive-dispensing chamber adjacent to the distal end of the insert. The at least one adhesive-dispensing chamber contains at least one part of an adhesive material within a chamber wall. The fastener-receiving insert system further includes a puncturing device operably engaged with and configured to puncture the chamber wall to release the at least one part of the adhesive material around the fastener-receiving insert.
Another aspect of the disclosure provides a method of forming a fastener-receiving insert system. The step of forming the fastener-receiving insert system includes disposing at least one adhesive-dispensing chamber adjacent to a distal end of a fastener-receiving insert having a proximal end and a distal end, and the at least one adhesive-dispensing chamber containing at least one part of an adhesive material within a chamber wall. The step of forming the fastener-receiving insert system further includes operably-engaging a puncturing device with the at least one adhesive-dispensing chamber, the puncturing device being configured to puncture the chamber wall to release the at least one part of the adhesive material around the fastener-receiving insert.
Another aspect of the disclosure provides installing a fastener-receiving insert system in a composite panel. The step of installing the fastener-receiving insert system in the composite panel includes placing a fastener-receiving insert system in an insert-receiving orifice defined by the composite panel, the fastener-receiving insert system comprising a fastener-receiving insert having a proximal end and a distal end, at least one adhesive-dispensing chamber adjacent to the distal end of the fastener-receiving insert, and containing at least one part of an adhesive material within a chamber wall, and a puncturing device operably engaged with the chamber wall. The step of installing the fastener-receiving insert system in the composite panel further includes applying pressure to the proximal end of the fastener-receiving insert in the insert-receiving orifice to compress the at least one adhesive-dispensing chamber. The step of installing the fastener-receiving insert system in the composite panel further includes puncturing the chamber wall with the puncturing device to release the at least one part of the adhesive material therefrom and to dispense the at least one part of the adhesive material between the fastener-receiving insert and the composite panel to secure the fastener-receiving insert within the insert-receiving orifice.

When the fastener-receiving insert system 10 is installed in the insert-receiving orifice 130, and urged into the insert-receiving orifice 130 until the proximal end 11 is substantially flush with the exterior surface of the composite panel 120, the puncturing device 18 is, in turn, arranged to puncture a chamber wall of the adhesive-dispensing chamber 14 and/or 16. For example, in one embodiment, the puncturing device 18 is arranged to puncture the common chamber wall 25 between the adhesive-dispensing chambers 14 and 16, causing the first part 17 of the adhesive material in the adhesive-dispensing chamber 14 to mix with the second part 19 of the adhesive material in the adhesive-dispensing chamber 16. The two parts 17, 19 of the adhesive material mix and actuate to form the actuated adhesive material. This actuated adhesive material is dispensed between the fastener-receiving insert 12 and the portion of the composite panel 120 defining the insert-receiving orifice 130 to secure the fastener-receiving insert 12 within the insert-receiving orifice 130.
In one embodiment, the fastener-receiving insert system 10 includes relief openings 24 defined by the proximal end 11 of the fastener-receiving insert 12, with the relief openings 24 being arranged to relieve excess adhesive material from the at least one adhesive-dispensing chamber (14, 16), after the adhesive material is actuated and dispensed to secure the fastener-receiving insert 12 within the insert-receiving orifice 130 defined by the composite panel 120.
In accordance with the foregoing, other aspects of the present disclosure provide a method 300 of forming a fastener-receiving insert system 10 for use with a composite panel 120, as shown for example in
Furthermore, the method 300 includes at step 320 wherein a puncturing device 18 is operably-engaged with at the at least one adhesive-dispensing chamber 14, 16. The puncturing device 18 having a puncturing point 22 is configured to puncture the chamber wall, for example, the common chamber wall 25 between the chambers 14 and 16, to release at least one part of the adhesive material (for example, a first part 17 of an adhesive material and/or a second part 19 of adhesive material) from first adhesive-dispensing chamber 14 and/or the second adhesive-dispensing chamber 16, when the fastener-receiving insert system 10 is installed in the insert receiving orifice 130. As the puncturing device 18 punctures the chamber wall, the first part 17 of the adhesive material and the second part 19 of the adhesive material are mixed and actuated. As further pressure is applied to the fastener-receiving insert system 10 to urge the fastener-receiving insert system 10 into the insert-receiving orifice 130, the chambers 14, 16, and the puncturing device 18 collapse, dissolve or compress, and the actuated adhesive material is dispensed between the fastener-receiving insert 12 and the portion of the composite panel 120 defining the insert-receiving orifice 130 to secure the fastener-receiving insert 12 within the insert-receiving orifice 130. Excess actuated adhesive material dispensed from the adhesive-dispensing chambers is then vented or relieved through a relief opening 24 defined by the proximal end 11 of the fastener-receiving insert 12 (
In another aspect, the present disclosure provides a method 900 of installing a fastener-receiving insert system 10 in a composite panel 120, as shown for example in
Furthermore, the method 900 includes at step 920 applying pressure to the proximal end 11 of the fastener-receiving insert 12 in the insert-receiving orifice 130 to compress the at least one adhesive-dispensing chamber (14, 16). This illustrated with reference to
As further pressure is applied, the fastener-receiving insert 12 is embedded within the insert-receiving orifice 130 such that the proximal end 11 of the fastener-receiving insert 12 is substantially flush with the upper face sheet 120A of the composite panel 120, and the adhesive-dispensing chambers 14, 16 are completely dissolved, compressed or collapsed. Furthermore, the puncturing device 18 is also completely dissolved, compressed or collapsed, though in some instances, this is not necessary (i.e., the intact puncturing device 18 serves as a spacer to maintain the proximal end 11 substantially flush with the upper face sheet 120A). The actuated adhesive material 30 is dispersed around the fastener-receiving insert 12 and into engagement with the honeycomb structure of the composite panel 120 defining the insert-receiving orifice 130, the fastener-receiving insert 12 is secured within the insert-receiving orifice 130. Excess adhesive material is relieved via relief openings 24 defined by the proximal end 11 of the fastener-receiving insert 12. Once the fastener-receiving insert 12 is in the desired position and orientation inside the insert receiving orifice 130, the actuated adhesive material is allowed to cure and set, thus ensuring a secure fit of the fastener-receiving insert 12 within the composite panel 120.
