偶联剂对玻璃纤维/环氧基复合材料界面介电性能的影响研究

EFFECT OF COUPLING AGENTS ON DIELECTRICAL PROPERTIES OF GLASS FIBER/EPOXY MATRIX COMPOSITE INTERFACE

摘要

摘要: 本文研究了五种偶联剂对玻璃纤维浸润性能和玻璃纤维/环氧基复合材料界面介电性能的影响。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相容性及化学反应活性得到改善;因此赋予了玻璃纤维与环氧基体间以良好的界面粘结性能,从而提高了玻璃纤维/环氧基复合材料界面的介电性能。其提高的幅度大小与偶联剂的极性及化学结构有关。

Abstract: Influence of five kinds of coupling agents on the wetting property of glass fiber and on the dielectrical property of glass fiber/epoxy composite interface was studied. The results show that after glass fiber being treated with coupling agents and activation energy of glass fiber for wetting being decreased, the reaction activity and wettability between glass fiber and epoxy resin matrix can be improved. A good interface adhesion of glass fiber/epoxy results in an improvement of dielectrical propertys of glass fiber/epoxy composite interface. Its improvement range depends on the polarity and chemical structure of the coupling agents.
