Abstract
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bicycle frame, and more particularly to a bicycle frame made of a carbon fiber composite material.
Although the frame of a bicycle is generally made of a metal such as aluminum, recently, a frame having improved strength and weight using carbon fiber is also used. Carbon fibers are not used solely to provide structural strength and are used in the form of composites combined with substrates such as resins. Generally, the carbon fiber composite material bicycle frame is produced by laminating a carbon fiber composite prepreg on each of two molds, placing a pressure-resistant tube between the two molds, closing the two molds, supplying air to the pressure- . However, such a conventional carbon fiber composite material bicycle frame has a problem that a metal mold having a complicated structure must be used, for example, a pressure-resistant tube must be installed.
It is an object of the present invention to provide a bicycle frame assembly made of a carbon fiber composite material.
According to an aspect of the present invention,

According to the present invention, all of the objects of the present invention described above can be achieved. Specifically, there is provided a bicycle frame assembly in which an SMC containing a carbon fiber as a reinforcing material is formed through a press molding process and formed by integrally assembling two frame members.
