抄録

Conducting bending test of CFRTP (CF / PLA) molded using polylactic acid as a base material and comparing the heat treatment time as a molding condition to see the change of mechanical property of CF / PLA by changing the heat treatment time Heat and quench by heating at 200 ° C. for 10 minutes. Place four films of PLA film and carbon fiber textile material on a steel mold, press at 200 ° C. for 10 minutes, and water-cool. After that, in this study, a strain gauge was attached to CFPLA which was subjected to heat treatment at 130 ° C. for 0, 3.5, 7 and 14 hours, respectively, and a bending test was conducted using a universal type horse testing machine. It is a study to evaluate the mechanical properties of CF / PLA and how to change the tendency of the mechanical properties of CFPLA by applying heat treatment.
