Abstract
The use of carbon-fiber-reinforced plastic (CFRP) parts is limited because of their high price and long manufacturing time, although CFRP are among of the lightest and stiffest materials in the world. We propose a method of stamping solidified CFRP sheets, in which CFRP sheets are sandwiched by dummy metallic sheets during stamping. The dummy metallic sheets act as heating media, as well as protective materials for CFRP sheets. In this investigation, the results of applying the proposed process to cold and warm V-bending are presented for investigating the characteristics of the fracture and bending of CFRP sheets.
