High-temperature interfacial property of quartz fiber/silicon-containing arylacetylene composites with aromatic amic acid-containing alkyne-terminated silane

Keywords： quartz fiber , silicon-containing arylacetylene , terminal-alkyne and aromatic amic acid-containing silane , imide ring , high-temperature interfacial reinforcement

运用自主设计合成的含有端炔和芳酰胺酸结构的硅烷偶联剂(CA-K)改善石英纤维(QF)/含硅芳炔(PSA)复合材料的高温界面黏结性能.FTIR、DSC以及TGA跟踪分析表明:CA-K在PSA固化时同步发生热闭环,形成耐热的酰亚胺环结构,CA-K同时参与PSA的固化;XPS分析推断出CA-K与纤维发生化学键合;CA-K处理后QF/PSA复合材料的界面黏结强度增加,常温下层间剪切强度(ILSS)和弯曲强度分别较未处理时提高了34.7％和40.4％,在250℃时ILSS和弯曲强度的保留率分别达到82.5％和54.9％,而500℃时ILSS和弯曲强度保留率为85.1％和64.2％.
