摘要: 本文讨论了五种偶联剂对玻璃纤维/环氧单向复合层板电性能和力学性能的影响.结果表明,玻璃纤维经偶联剂处理后,其浸润活化能降低,与环氧树脂基体间的化学反应活性得到改善.因此偶联剂赋予玻璃纤维与环氧树脂基体间以良好的界面粘结性,从而提高了玻璃纤维/环氧单向复合层板的电性能和力学性能,其提高的幅度大小与偶联剂的化学结构有关.Abstract: Influence of five kinds coupling agents on electrical and mechanical properties of glass fiber/epoxy laminated plate is discussed in this paper.The resuits are shown that after glass fiber being treated with coupling agent and activation energy of glass fiber for wetting being decreased, the reaction activity and wettability between glass fiber and matrix epoxy resin can be improved.A good interface adhesion of glass fiber/epoxy results in an improvement of electrical and mechanical properties of gjasp fiber/epoxy laminated plast.
