    摘要:

    对苯并噁嗪树脂应用于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/苯并噁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℃温度区间内苯并噁嗪树脂粘度保持在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/苯并噁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/苯并噁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 the range from 85℃ to 145℃, and has a wide low-viscosity temperature window and a long low-viscosity keeping time. The interlaminar shear strength(ILSS) of quartz/benzoxazine resin composites reaches 61.5MPa, the tensile strength and the flexural strength are more excellent than those of quartz/barium-phenolic resin composites. The mass ablation rate and line ablation rate of quartz/benzoxazine composites reach 0.0510g(s-1and 0.032mm(s-1 , respectively. Quartz/benzoxazine resin composites can be used as ablative materials and fabricated by RTM process.
