摘　　要：制备出一种新型的由双酚A型苯并噁嗪和环氧基笼型倍半硅氧烷组成的复合材料。对复合材料的结构,热性能和机械性能进行了考察。结果表明,在双酚A苯并噁嗪树脂中加入一定量的环氧基笼型倍半硅氧烷,可以有效提高苯并噁嗪树脂的热性能和机械性能。Bisphenol-A type benzoxazine/POSS-epoxide hybrid resins were prepared, curing behavior of the hybrids, thermal and dynamic mechanical capability of cured composites were characterized. DSC analysis results showed the initiative curing temperature of hybrids was enhanced, and DMA.TGA analysis results showed the hybrids possessed higher storage modulus, glass transition temperature and thermal stability.
