International ClassesB29C 043/18B29C 043/10 AbstractA method of making generally hollow components and assemblies for a bicycle frame from composite materials, such as unidirectional structural fibers impregnated with a heat curable synthetic resin. Opposing parts of at least two adjacent wall sections are overlapped to form a shell and the overlapped parts are compressed together between internal and external pressing members. The shell is then cured while under compression to provide a pressure cured juncture integrally uniting the wall sections and forming a generally hollow bicycle frame component.Other References
