Patent ID: 8828169

Claim:
A method for manufacturing a composite bicycle component comprising: applying a fiber-reinforced polymer material around a pouched member containing an evaporable substance to obtain a FRP covered pouched member; disposing the FRP covered pouched member within a metallic member after the applying of the fiber-reinforced polymer material around the pouched member; heating the FRP covered pouched member to expand the FRP covered pouched member due to an increase of an internal pressure resulting from the evaporable substance expanding within the pouched member so that the fiber-reinforced polymer material bonds to an inner surface of the metallic member to obtain a composite hollow member in which the pouched member is adhered to the inner surface of the metallic member; and removing ends of the pouched member such that a portion of the pouched member adhered to the inner surface of the metallic member forms a part of the composite bicycle component after manufacture.
