| 摘 要： | 对苯并(啞心)嗪树脂应用于RTM工艺制备石英纤维增强复合材料进行了研究.系统考察了该树脂的工艺性能及力学性能,制备并测试了石英/苯并(啞心)嗪复合材料的力学性能及耐烧蚀性能,并将相关性能与钡酚醛与石英/钡酚醛进行了比较.结果表明,在85℃～145℃温度区间内苯并(啞心)嗪树脂粘度保持在800mPa·s以下,树脂具有较宽的低粘度温度平台和较长的低粘度保持时间.力学性能及耐烧蚀性能研究表明,石英/苯并(啞心)嗪复合材料的层间剪切强达到了61.5MPa,拉伸强度和弯曲强度显著优于石英,钡酚醛复合材料,质量烧蚀率和线烧蚀率分别为0.0510g·s-1和0.032mm·s-1.石英/苯并(啞心)嗪复合材料是一种可采用RTM工艺制备的耐烧蚀材料.

| Abstract: | Benzoxazine resin is used to fabricate quartz fiber reinforced composites by RTM process in the paper.The processing properties and mechanical performances of benzoxazine resin are studied systematically,and quartz/benzoxazine resin composites are manufactured by RTM to test their mechanical performances and ablation properties.Some properties are compared with those of barium-phenolic resin and its quartz fiber composites.The results show that benzoxazine resin maintains low-viscosity less than 800mPa.s in... |
