Abstract In order to improve the fibre-matrix interaction in carbon fibre reinforced composites the polycarbonate (PC) matrix polymer was modified by the introduction of ethyl-3,5-dihydroxybenzoate as reactive sequences in the polycarbonate backbone. This promising strategy can be considered as an alternative approach to the modification of the carbon fibre surface to control and tailor the adhesion between carbon fibres and polymer matrix. The modification of the polycarbonate demonstrated improved adhesion to carbon fibre in pressed films, which was observed with microscopy-ATR-FTIR and SEM when compared to unmodified polycarbonate. Single fibre pull-out testing subsequently confirmed the improved adhesion, demonstrating higher interfacial shear strenght for the functionalized polycarbonate.

功能性聚碳酸酯提高对碳纤维的附着力

摘要 为了改善碳纤维增强复合材料中纤维-基体的相互作用,通过在聚碳酸酯主链中引入 3,5-二羟基苯甲酸乙酯作为反应序列对聚碳酸酯 (PC) 基体聚合物进行了改性。这种有前景的策略可以被视为一种替代方法来改性碳纤维表面,以控制和定制碳纤维与聚合物基体之间的附着力。与未改性的聚碳酸酯相比,聚碳酸酯的改性证明了对压制薄膜中碳纤维的粘附性提高,这是通过显微镜-ATR-FTIR 和 SEM 观察到的。单纤维拔出测试随后证实了粘合力的提高,表明官能化聚碳酸酯具有更高的界面剪切强度。
