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。 This article discusses the effect of five coupling agents on the electrical and mechanical properties of glass fiber / epoxy unidirectional laminate. The results show that the activation energy of the glass fiber is reduced after the coupling agent treatment, and the chemical reaction activity with the epoxy resin matrix is ​​improved. Therefore, the coupling agent confers good interfacial adhesion between the glass fiber and the epoxy resin matrix, thereby improving the electrical and mechanical properties of the glass fiber / epoxy unidirectional composite laminate. The magnitude of the increase is similar to that of the coupling agent The chemical structure of the.
