摘要/Abstract

摘要： 以含硅多芳炔化合物(PSA)与1,3,5-三叠氮甲基-2,4,6-三甲基苯(TAMTMB)为原料，通过1,3-偶极环加成反应制备了新型含硅聚三唑树脂Si-PTA3，考察了树脂的流变性能、固化行为、热性能及单体配比对其热性能的影响。采用模压法制备了单向T700碳纤维增强的Si-PTA3树脂复合材料T700/Si-PTA3，测定了其力学性能。结果表明，Si-PTA3树脂具有良好的加工性能，可在80℃下固化，耐热性较好；炔基与叠氮基摩尔比为1.1:1.0时树脂固化物的热性能最好，玻璃化转变温度达334℃，在氮气中热失重5%时的温度达351℃；复合材料T700/Si-PTA3常温下的弯曲强度高于1670 MPa，250℃时弯曲强度保留率超过67%。
