シランカップリング処理したガラス繊維強化型樹脂(GFRP)厚肉板の曲げ強度に及ぼす電子線照射の効果

抄録

  Effects of silane coupling treatment and electron beam (EB) irradiation on bending test of glass fiber reinforced epoxy polymer (GFRP) thick sheet were studied. EB irradiation increased the bending strength and its strain of GFRP thick sheet with silane coupling treatment. EB irradiation also enhanced the apparent hardening modulus (dσ/dε) of bending deformation and increased the deformation energy of GFRP thick sheet with silane coupling treatment. The deformation energy depends on the strain improvement at the maximum bending stress of epoxy resin and glass fiber and the interfacial friction force.
