Abstract
The forming processes at warm condition of carbon-fiber-reinforced plastics （CFRPs） sheets for mass production have been investigated. The bendability and stretchability can be evaluated by a stretch-bending test and a stretching test, respectively. A stretch-bending test is a bending test in which a tensile load is placed on a sheet. In the stretching test, a method of fixing the specimen is a kind of important condition for CFRP. We have proposed suitable forming tests and evaluated the formability of CFRP sheets compared to the metal sheets.
