摘要
从固化反应动力学、热分解动力学与耐烧蚀性能等方面研究了不同配比酚醛/苯并噁嗪共混树脂,并通过浸渍高硅氧玻璃布制备了相应的树脂复合材料。对其高常温力学、热学与耐烧蚀性能进行了研究。结果表明:共混树脂复合材料常温拉伸强度(214 MPa)、弯曲强度(332 MPa)、压缩强度(217 MPa)与高温层间剪切强度(21.6 MPa)等力学性能均高于酚醛树脂复合材料,热学与烧蚀性能符合耐烧蚀复合材料要求,可以作为一种性能优良的耐烧蚀复合材料。
The blend resin with different proportions of benzoxazine/phenolic was investigated on the kinetics of reaction, thermal degradation kinetics and ablative property. The resin composite was prepared by impregnating glass cloth. The high temperature and normal temperature mechanical properties, the thermal properties and the ablative properties of tbe composite were investigated. The results show that the blend resin composite has excellent mechanical properties at high temperature and normal temperature and its thermal properties meet the needs of ablative materials. This blend resin composite can be used as the ablative composite.
