摘要: 在玻璃布增强氰酸酯树脂(CE)基复合材料中加入氮化硼(BN)粒子,制得CE/玻璃布/BN复合材料。研究了BN粒子含量对复合材料性能的影响。结果表明,经偶联剂处理的BN粒子使体系凝胶时间缩短,反应活性略有提高。BN粒子的加入可以明显提高复合材料的弯曲强度和层间剪切强度,在BN加入量为8 %时,复合材料的弯曲强度和层间剪切强度达到最大值,分别提高了5 %和36 %。加入BN粒子后,复合材料的起始热分解温度都较未填充体系有所提高,耐热指数升高,热稳定性相应提高。

Abstract: Boron nitride (BN)/cyanate ester resin/glass fiber composites were prepared in order to enhance the properties. The effects of BN particles on the reaction activity of cyanate ester resin, mechanical properties, and heat resistance of the composites were investigated. It was found that BN particle had little influence on reaction activity of cyanate ester resin. Inclusion of 8 % couple agent treated BN particles resulted in 5 % and 36 % increase in the flexural strength and interlaminar shear strength, respectively. The addition of BN particles to the composites also increased the initial decomposition temperatures, heat resistance index, and thermal stability of cyanate ester resin composites.
