中文摘要: 用双（N-间乙炔基苯基邻苯二甲酰亚胺）醚（DAIE）改性苯乙炔基硅氧硼烷（PESB）制得复合材料基体树脂(PESB DAIE)。通过FT-IR、DSC和TG研究了PESB DAIE的固化反应及耐热性。将PESB DAIE与纤维复合制得复合材料，研究了该材料的耐热性、弯曲强度及断面形貌。研究结果表明，固化物在氮气气氛下质量损失5%时的温度(T5%)为576 °C，空气气氛下T5%为507 °C。复合材料在500 °C下放置10 min后质量保留率为97.0%，弯曲强度为176 MPa。

Abstract:Phenylethynyl siloxane borane (PESB) was modified with di((N-m-acetylenylphenyl) phthalimide) ether (DAIE) and used as the matrix resin of composite. The curing mechanism and heat resistance were studied with FT-IR, DSC and TG. The flexural strength, heat resistance and fracture surface of the composites were also studied. Results showed that the temperature of 5% weight loss (T5%) of the cured blends was 576 °C in nitrogen and 507 °C in air. The mass retention of the composites after placed in 500 °C environment for 10 min was 97.0%, and the flexural strength was 176 MPa.
