含炔基酚醛树脂改性PSA及碳纤维布/PSA-EPAN复合材料性能
|
Abstract:
合成了乙炔基苯基偶氮酚醛树脂（EPAN），通过溶液共混的方法用其对含硅芳炔树脂（PSA）进行改性，研究了PSA-EPAN树脂的热性能，并制备了PSA-EPAN的碳布预浸料，经热模压制备碳纤维布（T300CF）增强PSA-EPAN复合材料，对其力学性能进行了研究。结果表明：EPAN均匀分布于PSA树脂中，EPAN共混改性PSA树脂的固化温度提高，混入质量分数为7%的EPAN，N2中固化PSA-EPAN树脂在800℃残留率超过90%，其玻璃化转变温度高于500℃，PSA-EPAN共混树脂浇铸体的弯曲性能高于PSA树脂，达40.7 MPa，提高了95.5%；PSA树脂经T300CF/PSA-EPAN复合材料力学性能显著提高，弯曲强度达到了423.5 MPa，提高了74%，层间剪切强度（ILSS）提高至29.53 MPa，增加了65%。 An ethynyl phenyl azo novolac resin(EPAN) was prepared by Diazo coupling reaction.The ethynyl-containing phenolic resin was used to modify the silicon-containing arylacetylene resin (PSA) through solution blending. The thermal properties of the modified PSA were studied. The modified PSA-EPAN was used to prepare the carbon fabric prepregs. The T300 carbon fabric (T300CF) reinforced the modified PSA-EPAN composites were thermally press-molded, and the mechanical properties of the composites were further investigated. The results show that the EPAN can be well distributed in the PSA matrix, and the cure temperature of the PSA-EPAN blend resin enhances. With mass fraction of 7% EPAN in the PSA-EPAN blend resin, the residual yield at 800℃ in N2 of the cured blend resin is more than 90%, and the glass transition temperature of the cured blend resin is more than 500℃. The flexural strength of the cured PSA-EPAN blend resin reaches 40.7 MPa which is more than that of the cured PSA resin and increases by 95.5%. The flexural strength and interlayer shear strength of the T300 carbon fabric reinforced PSA-EPAN blend resin composite can reach 423.5 MPa and 29.5 MPa, increasing by 74% and 65%, respectively. 装备预研教育部联合基金（6141A0222）；中央高校基本科研业务费专项资金
