基于光纤传感的复合材料冲击的激励-响应关系
摘要
本文介绍了硅橡胶/环氧树脂/酚醛树脂三元共混体系。研究了单相和共混体系的固化。发现了以酚醛树脂为过渡相实现“就地增容”解决三者相容性的方法。分析了共混体系不分层的原因。并结合黏度测试、光学显微镜测试、差示扫描量热测试研究了不分层三元体系的形成过程以及固化规律。通过扫描电镜等测试方法研究了固化后产物的微观结构,并做了力学测试。
结果得到了一种不分层的共混体系。并发现固化后的三元体系中,环氧树脂主要以颗粒形式分散在固化后的体系中,酚醛树脂以颗粒状和连续状两种形式分布,硅橡胶则以连续相作为基体分布在体系中。这和实验设想的“酚醛树脂作为过渡相”的思路相符合。并发现通过高温处理后的体系固化度更高,力学性能更好。

Abstract
The thesis introduces silicone/epoxy resin/phenolic resin ternary blend system. The curing properties of one-component and the blending system were studied. We found the phenolic resin as transitional phase which we call“on-site compatibilizing ”method to solve the three compatibility. Analyzing the blending system. Viscosity test, optical microscope test, differential scanning calorimetry test were used to analysis the forming process and the curing rule of the system. By scanning electron microscope, the microcosmic structure of the curing product was studied.
A homogeneous system was obtained. And in the system, curing epoxy resin was scattered mainly in the form of particles, and the curing phenolic resin was distributed in the form of both particals and continuous phase. Silicone was found in continuous phase as the matrix in system. This coincides to the idea of using phenolic resin as the transitional phase. And after the treatment of high temperature, higher degree of curing system and better mechanical properties of the material were obtained.
Keywords silicone; Epoxy resin ; Phenolic resin ; compatibility; on-site compatibility-increasing ;curing
