COMPOSITE COMPONENT, METHO OF MANUFACTURING THE SAME, RACK BAR, AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a composite component which has light weight and high bending strength, a method of manufacturing the composite component, a rack bar, and a method of manufacturing the rack bar.SOLUTION: A rack bar 1 as a composite component is equipped with metallic members 2 and 3 which include cylindrical hollow portions 9 and 13; a tube 4 which includes end portions 41 and 42 adhered to inner peripheries 9a and 13a of the hollow portions 9 and 13; and a hollow bag body 5 which is fitted with an inner periphery 4a of the tube 4, and can be pressurized and expanded from the inside. A recession/projection engaging portion for preventing slipping-off is included, in which the inner peripheries 9a and 13a of the hollow portions 9 and 13 of the metallic members 2 and 3 and outer peripheries 41a and 42a of the end portions 41 and 42 of the tube 4 are engaged with each other. The tube 4 is made from a CFRP including resin adhered to the inner peripheries 9a and 13a of the hollow portions 9 and 13 of the metallic members 2 and 3 due to thermal hardening.
