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

  • 摘要: 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%。
    Abstract: A novel silane coupling agent (CA-K), designed and synthesized by our team, which contains terminal-alkyne and aromatic amic acid groups, was employed to reinforce the interfacial bonding performances of quartz fiber(QF)/silicon-containing arylacetylene (PSA) composites at high-temperature. FTIR, DSC and TGA trace analysis indicate that the imide ring structure is formed in CA-K with PSA curing process, and CA-K takes part in the curing of PSA simultaneously. XPS analysis calculates that chemical boundings form between CA-K and fiber. The interfacial bonding strength of QF/PSA composites are improved after CA-K treatment. The interlaminar shear strength (ILSS) and flexual strength are increased by 34.7% and 40.4% compared with those of unmodified at room temperature and the retention ratios of ILSS and bending strength are 82.5% and 54.9% when the temperature rises up to 250 ℃, 85.1% and 64.2% when it is 500 ℃.
