前言评价玻璃纤维在树脂基体中的浸透速度,至今在国内外还没有标准的试验方法。ISO 3717技术报告介绍了一种“靶环法”,用于测定玻璃纤维原丝毡片和机织物被树脂浸渍时间的试验方法。该方法以技术报告的形式发表,其原因是由于试验的主观性和试验结果的再现性差。我们认为该方法利用试样被树脂完全浸透所需的时间来评价浸透速度是可行的,关键是注意试样的制备和掌握影响试样结果的各种因素。另外树脂完全浸透试样的过程一
Preface Evaluation of glass fiber penetration rate in the resin matrix, so far at home and abroad there is no standard test method. ISO 3717 Technical Report describes a “target ring method” for the determination of glass fiber mat and woven fabric impregnated resin testing time. This method is published as a technical report due to the subjectivity of the test and the poor reproducibility of the test results. In our opinion, it is feasible to evaluate the penetration rate by using the time it takes for the sample to completely penetrate the resin. The key is to pay attention to the preparation of the sample and grasp the various factors that affect the result of the sample. In addition the resin completely saturated with the sample process one
