FRP材の弾性特性に及ぼす環境温度の影響に関する実験的検証

抄録

This paper presents the experimental study for elastic environmental characteristics of thermoplastic fiber reinforced plastics materials. For this purpose, tensile test is carried out for the fiber reinforced plastic material of carbon fibers and the resin of acrylic, nylon and epoxy, and Young's modulus and Poisson's ratio are estimated experimentally for the cases of different environmental temperatures. Furthermore, the experimental modal analysis is conducted for the rectangular plates of the materials, and the numerical calculations for the free vibration problem of the plate are also carried out by using the material properties obtained from the tensile tests.
