J.Assistant: Cuff, Michael Attorney, Agent or FirmInternational ClassB62K 015/00AbstractA composite bicycle frame having at least a portion of the frame walls reinforced with an internal layer of honeycomb material is presented. The honeycomb material is essentially sandwiched between interior and exterior sections of the frame wall, with the interior and exterior sections of the frame wall each being comprised of a plurality of overlaid layers composite material. Each layer of composite material is comprised of a multiplicity of high strength, unidirectional carbon fibers embedded in an epoxy resin. Several layers of composite material are stacked on top of each other and arranged so that the fibers in one layer cross over the fibers in an adjacent layers. The layers are cut into shapes and molded together using a cavity mold and internal pressure bladder in order to construct a substantially hollow, unitary frame member. | |
