摘　　要：SiO2基复合材料是近年来发展起来的务性能多功能透波复合材料，广泛应用于弹头的防热—透波部件。本文介绍了由硅溶胶转化的SiO2基复合材料的结构特点和存在的主要问题，利用有机硅树脂进行应用研究。讨论了有机硅树脂对SiO2基复合材料的介电、烧蚀及力学性能的影响。试验表明有机硅树脂能够有效地提高SiO2基复合材料的各项性能。SiO2 matrix oomposite, a high performance and multifunctional ceramic matrix oomposite, is developed in recent years. It's extensively used as heat shield and electronmagnetic wave transparent material for nose cone. The constitution and primal problems of SiO2 matrix composite converted from silicasol are intreduced in this paper. The application research was carried out by using slicone resin in the materials. The effects of the resin on the dielectric,ablative and mechanical properties of the material were discussed. The results show that the properties of SiO2 matrix composite are improved by using silicone resin.
