采用近红外漫反射光谱技术对高硅氧/酚醛预浸布的树脂含量、挥发分含量和预固化度等质量指标进行了在线测定。
The resin content, the volatile content and the pre-curing degree of the silica/phenolic resin prepreg cloth were on-line determined by near infrared diffuse reflection spectrum.
结果表明 ，高硅氧玻璃纤维布增强聚四氟乙烯复合材料在上述因素影响下 ，其介电常数在 2 .90～ 3.30的范围内变化 ，其中环境湿度是主要的影响因素。
The results showed that its dielectric constant changes in the scope of 2.90 to 3.30 under the influence of the factors mentioned above, among which the environmental humidity is a dominant one.
