<p>PURPOSE:To provide the subject prepreg capable of forming an uniform pipe not producing wrinkles even when a step part is formed on the pipe, and not causing especially the deterioration of the compression strength, impact strength, torsion fracture strength, etc. CONSTITUTION:A fiber-reinforced prepreg 1 comprising a fiber-reinforced composite resin layer 4 and a metal foil layer 3 laminated to one side of the composite resin layer 4, the composite resin layer 4 comprising reinforcing fibers 2 and a matrix resin 5 impregnated into the reinforcing fibers 2, is characterized by forming slits 3a in the metal foil layer 3.</p> |
