ガラス繊維強化塩化ビニルの疲労き裂伝ぱに及ぼす安定剤と繊維の影響

抄録

From the observation of the fatigue crack growth behaviors and fractographs, the short glass fiber reinforced polyvinyl chloride with Sn series stabilizer was seemed to be anisotropic little and ductile, and the fiber reinforced polyvinyl chloride with Pb series stabilizer to be anisotropic and brittle during stable crack growth, though the mechanical properties of two kinds of fiber reinforced polyvinyl chlorides were anisotropic. It was found that the configuration of fatigue fracture surface ralated to the constants m and C values in Paris' Law, and the fatigue crack growth behaviors were influenced by the adhesive property between fibers and matrix resin due to the stabilizer.
