Patent Application
20140198437
This disclosure relates generally to information handling systems, and relates more particularly to the use of continuous bamboo fiber reinforced polymer in an information handling system chassis.
As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option is an information handling system. An information handling system generally processes, compiles, stores, or communicates information or data for business, personal, or other purposes. Because technology and information handling needs and requirements can vary between different applications, information handling systems can also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information can be processed, stored, or communicated. The variations in information handling systems allow information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems can include a variety of hardware and software resources that can be configured to process, store, and communicate information and can include one or more computer systems, data storage systems, and networking systems.

Bamboo layer 440 is prepregnated with matrix material and provides stiffness and rigidity to section 310, and by extension to chassis bottom 210. Bamboo layer 440 is prepregnated with matrix material, and is represented here as a thin sheet of bamboo. In a particular embodiment, section 310 can include one or more additional layers of bamboo, and the layers can be laid out such that the grain pattern in the bamboo sheets are perpendicular to each other, such that the grain pattern in the bamboo sheets are parallel to each other, or in another configuration. In another embodiment, bamboo mat 445 is a woven mat of bamboo slats or fibers that are prepregnated with matrix material and incorporated into section 310, either in addition to bamboo layer 440, or as a substitute for the bamboo layer. In a particular embodiment, the material used to prepregnate one or more of fiber layers 430 and 450 and bamboo layer 440 is the same material as used for bonding material 420.
If the fiber layer is the last fiber layer to be place before adding the bamboo layer, the “YES” branch of decision block 508 is taken, and the bonding material is applied to the last fiber layer on block 510. For example, bonding material 420 can be applied to outer layer 410. A prepregnated bamboo layer is placed into the form in block 512. Here, bamboo layer 440 can be placed on top of fiber layer 430. A decision is made as to whether or not the bamboo layer placed in the form is the last bamboo layer to be place before adding the additional fiber layers in decision block 514. If not, the “NO” branch of decision block 514 is taken and the method returns to block 510 where the bonding material is applied to the bamboo layer.
If the bamboo layer is the last bamboo layer to be place before adding the additional fiber layers, the “YES” branch of decision block 514 is taken, and the bonding material is applied to the last bamboo layer on block 516. A prepregnated fiber layer is placed into the form in block 518. Here, fiber layer 430 can be placed on top of bamboo layer 440. A decision is made as to whether or not the fiber layer placed in the form is the last fiber layer to be place before adding a second outer layers in decision block 520. If not, the “NO” branch of decision block 520 is taken and the method returns to block 516 where the bonding material is applied to the fiber layer.
If the fiber layer is the last fiber layer to be place before adding the second outer layer, the “YES” branch of decision block 520 is taken, and the bonding material is applied to the last fiber layer on block 522. The second outer layer is placed into the form in block 524. Here, outer layer 410 can be placed on top of fiber layer 430. The form is cured and processed as needed or desired in block 526, and the method ends in block 528. For example, the form with the layers can be pressure treated, heat treated, chemically treated, subjected to another treatment, or a combination thereof. The skilled artisan will recognize that, although the method is described in terms of the layer arrangement of section 310, other arrangements and layering orders can be performed as needed or desired.
