摘要：将双(N-间乙炔基苯基邻苯二甲酰亚胺)醚(DAIE)和双酚A型氰酸酯(CE)分别加到聚苯乙炔基苯基硅氧硼烷(PSOB)和三苯乙炔基苯基硅烷(PTPES)混合体系中进行改性,制得两种纤维增强复合材料PSOB-PTPES-DAIE和PSOB-PTPES-CE。研究了固化后树脂的热稳定性能、力学性能、介电性能和耐水性能。结果表明:两种改性树脂高温下均保持了良好的耐热性能,在氮气中质量损失5%时的温度(T5%)最高可达534°C,800°C下质量保留率最高可达62.9%。所制备的两种复合材料体系常温下弯曲强度可达250 MPa以上,240°C下的弯曲强度最高可达202 MPa。饱和吸水率最低可达1.4%,耐水性能优良。不同处理条件下的复合材料介电常数与介电损耗角正切值变化较小,介电性能良好。
Di-N-m-acetylene-phenylphthalimide-ether（DAIE） and cyanate ester resin（CE） were used separately to modify the poly（phenyl（phenylethynylsilyl）oxide-phenylborane） terminated with phenylace-（tylene）（PSOB）.Two types of fiber reinforced composites（PSOB-PTPES-DAIE and PSOB-PTPES-CE） were prepared.The thermal stability,mechanical strength,dielectric and water resistance properties of the cured resins were investigated.It was indicated that both of the two modified resins exhibited high-temperature resistance with temperature of 5% mass loss up to 534（°C） and the maximum char yield of（62.9%） at 800 （°C） in N_2 atmosphere.The flexural strength of the two types of composites was more than 250 MPa at room temperature and reached the maximum of 202 MPa at 240（°C）. They exhibited well water resistance and their saturated water absorbing ratio reached the minimum of 1.4%.In different processing conditions,the dielectric constant and dielectric loss angle tangent of the composite showed little changes and their dielectric properties were excellent.
