摘要

灼烧法是玻纤复合材料树脂含量测定的常用方法，但是对于有机硅树脂类的玻纤复合材料，不能通过灼烧完全去除掉树脂基，无法采用此方法进行测试，通过测定玻纤、样品和树脂的密度可以计算出其树脂含量。本文采用密度法和灼烧法对同一批玻纤复合材料进行树脂含量的测定，通过比较两种方法的测量结果以及不确定度可以得到：密度法的树脂含量结果为40.8%，灼烧法树脂含量结果为38.6%，密度法较灼烧法偏高2.2%；密度法的扩展不确定度为1.2%，灼烧法的扩展不确定度为0.3%。灼烧法较密度法更加准确，但不适用于有机硅树脂的玻纤复合材料。密度法可以适用于有机硅树脂的玻纤复合材料并可以满足指标的测试要求，因此可以替代灼烧法对样品进行测试，需要严格把控实验过程提高测试结果的准确性。

Abstract

Burning method is widely used in determining the resin content of glass fiber composite materials. The burning method can not be used to determine the resin content in the glass fiber composite of organosilicon resin, as the resin base can not be completely removed by burning.Density method is to calculate the resin content by measuring the density of glass fiber, sample and resin. Two different method are used to test the resin content of same batch of glass fiber composite materials. According to the results, the resin content of the density method is 40.8% and the burning method is 38.6%. The expanded uncertainty of the density method is 1.2% and the burning method is 0.3%. The accuracy of density method is slightly lower than that of burning method, but it can be used to determine the resin content of silicone resin glass fiber composites and meet the index requirements. Therefore, the density method can replace the burning method to test the samples, but the experimental process needs to be strictly controlled to improve the accuracy of the test results.
