PRODUCING METHOD FOR BIKE'S CARBON RIM

摘要

PURPOSE: A method for producing a carbon rim of a bike is provided to ensure stable mounting of spoke connectors and tires on the carbon rim by attaching alloy inserts on the inner and outer perimeters of the rim. CONSTITUTION: A method for producing a carbon rim of a bike is as follows. A combined element is prepared by attaching first and second inserts(31,32) to the inner and outer perimeters of an air tube. The exterior of the combined element is wrapped with polymer composite(C). The combined element is put in an inner mold. The inner mold is put in an outer mold. A rim(R) is molded with heating and pressing, and then separated. High pressure air is injected to the inner side of the rim in order to remove the residual materials.
