摘要:文摘采用胺解法合成了二(3-乙炔基苯胺)-二甲基硅烷(SZ),并与含硅芳炔(PSA)树脂熔融共混制备了PSA/SZ。利用一系列测试手段考察了PSA/SZ树脂的流变行为、固化反应、热稳定性、弯曲、介电性能以及石英布增强PSA/SZ复合材料的力学性能。结果表明,硅氮烷SZ的加入有效降低了PSA/SZ树脂的黏度,PSA/SZ浇铸体的弯曲强度提高了62.7%,石英纤维增强PSA/SZ复合材料的弯曲和层剪强度分别提高了18.7%和60.4%。
A silicon-containing arylacetylene resin (PSA) was modified by blending bis (3-acetylenephenyl) dimethylsilazane(SZ) synthesized by an aminolysis procedure. A series of test methods were used to investigate the rheological behavior, curing reaction,thermal stability,flexural and dielectric properties of PSA/SZ. The mechanical properties of quartz fiber reinforced composites were also measured. The results show that with the increase of SZ, the viscosities of PSA/SZ resins decrease remarkably, the flexural strength of PSA/SZ resin increases by 62.7%, the flexural strength and interlaminar shear strength of quartz fiber reinforced PSA/SZ resin composite increase by 18.7% and 60.4%, respectively.
