Abstract
The invention provides an improved method for forming a composite material mainly composed of carbon fiber. It is difficult to form an H-shaped structural member formed of a prepreg material having carbon fiber fabric impregnated with epoxy resin into a member having curvature. Thus, the structural member is divided into two bendable constructional elementsand, which are bent to given curvature then adhesively-bonded to form a structural member having curvature.
