| 摘 要： | 研究了不同溶剂对于RTM石英/酚醛复合材料溶液浸润过程的影响.采用X光电子能谱(XPS)和原位电子顺磁共振(EPR)研究了石英纤维表面硅烷偶联剂和不同酚醛树脂溶液组分间的界面化学反应.采用TGA和层间剪切强度(ILSS)测试方法研究了溶剂对酚醛树脂分布和材料界面结合强度的影响.结果表明,溶剂能够与酚醛树脂在石英纤维表面形成竞争性吸附,从而影响树脂在RTM模具内部不同位置的分布和复合材料的力学性能.随着溶剂形成氢键能力的增强,其影响程度依次为四氢呋喃＜丙酮＜乙醇.

| Abstract: | The effects of different solvent species on resin transfer molding(RTM) solution impregnation process of silica fiber/phenolics composites were investigated.XPS and in-situ electron paramagnetic resonance(EPR) spectra were used to examine the interfacial chemical reaction between silane coupling reagent on silica fiber surface and the components of phenolic resin solution.Resin distribution and interfacial adhesion were evaluated by TGA and interlaminar shear strength(ILSS) measurements.The results show that solvents compete with phenolic resin for the adsorbing sites on the silica fiber.As increase in hydrogen bonding capacity of solvent used in this study,the extent of solvent effect is in the following order: THF
