摘要: 用丙酮萃取了T 700碳纤维织物的表面处理剂,分析了处理剂的主要成份,考察了丙酮萃取次数与碳纤维表面处理剂含量之间的变化规律,采用真空辅助灌注成型工艺制备了带有不同含量处理剂的碳纤维增强乙烯基树脂基复合材料,并对其力学性能进行了测试。结果表明,处理剂的主要成份为双酚A环氧树脂,含量约为1.5%,碳纤维经丙酮萃取后表面粗糙度增加,增大了树脂的浸润性,其复合材料的力学性能尤其是弯曲强度得到显著提高。

Abstract: Acetone was used to extract the treatment agents on the surface of T700 carbon fiber fabric, and the major chemical components of treatment agents were analyzed, where the relationships between the extraction time and the content of treatment agents on the surface of carbon fiber fabric were studied. Carbon fibers reinforced composites with different content of treatment agents were prepared by vacuum-assisted resin infusion molding (VARI) process, and their mechanical properties were tested. The results indicated that the main component of treatment agents was BPA epoxy resin, with content of ~1.5%. Additionally, the surface roughness was increased after solvent extraction, which improved the wettability of resin matrix. Moreover, the mechanical properties, especially the bending strength, were significantly increased.

Key words: carbon fiber, treatment agents, solvent extraction, mechanical properties, bending strength, interface
