摘　　要：采用原位的溶胶-凝胶法,以烷氧基金属化合物如正硅酸乙酯(TEOS)等作为硅源,制备SiO 2/EP有机-无机互穿网络结构的聚合物,无机相与有机相之间的均匀分散,起到质点增强的作用,大幅度提高聚合物的物理力学性能。以上述的复合物作为基体树脂,制备玻璃纤维增强复合材料,研究了基体树脂对纤维增强复合材料的力学性能和吸水性能的影响。Using the alkoxy metal compounds,such as ethylsilicate（TEOS）,as a silicon source the SiO2/EP organicinorganic interpenetrating network structure polymer.The inorganic phase and the organic phase are evenly dispersed each other in the system.The mesostructured silica plays an enhanced role in the particles and improved the mechanical properties of the polymer greatly.Using the aforesaid hybrid polymer material as the matrix resin,the effects of the matrix resin on the mechanical properties and water absorption of the fiber-reinforced composite materials were investigated.
