International ClassesB29C 043/18B29C 043/10 AbstractA method of molding generally hollow components and assemblies for a bicycle frame of composite materials, such as heat curable synthetic resins reinforced with structural fibers. The entire bicycle frame may be one integrally united piece. Layers of the composite material are shaped to form a shell for the frame component. Uncured portions of this shell are then compressed against the surfaces of a mold by a pressing member such as an inflatable bladder routed to the outside through a passageway passing through a metal sleeve.Other References
