一、前言树脂基体对玻璃纤维的浸润性决定其复合材料的性能。过去我们一般都是用复合材料的层间剪切强度来比较树脂与纤维的粘合程度,以此评价树脂对纤维的浸润性能。对于浸润性的测定,在国内外至今还没有标准方法。近几年,国内已有单位参照IS03717“耙环法”技术报告的原理进行了研究工作,提高了方法的准确性和重复性。该方法已被同行广泛采用。 I. Introduction The wettability of the resin matrix to the glass fiber determines the properties of the composite. In the past we generally use the composite material interlaminar shear strength to compare the degree of resin and fiber adhesion, in order to evaluate the resin wettability of the fiber. For the determination of invasiveness, there is no standard method at home and abroad. In recent years, some domestic units have made research work referring to the principle of IS03717 “Rake-ring Method” technical report, which has improved the accuracy and repeatability of the method. This method has been widely adopted by peers.
