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。
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(T_(5%)) 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.
