摘要: 分别采用双酚A环氧树脂乳液、乙烯基酯树脂乳液、醚类乳化剂乳液对国产碳纤维进行上浆,测试比较了三种上浆剂对碳纤维的表观、毛丝量、展纱性、硬挺度、吸水率、表面能及其复合材料层间剪切强度的影响。双酚A环氧树脂有利于改善纤维表面状态,提高纤维集束性;醚类的乳化剂有利于降低纤维的毛丝量,改善纤维的展纱性;乙烯基酯树脂可以提高纤维的集束性及硬挺度。三种上浆纤维表面能从大到小依次为环氧树脂、醚类乳化剂、乙烯基酯树脂;吸水率从小到大依次为环氧树脂、乙烯基酯树脂、醚类乳化剂。上浆剂中组分的吸水率高低不是影响碳纤维复合材料层间剪切强度的决定性因素。

Abstract: Three main components of the sizing agent, i.e., biphenyl A epoxy resin, vinyl ester resin and ether emulsifier for carbon fiber, were comparatively studied on the physical properties such as the surface properties, fuzz weight, splitting rate, hardness, water absorption rate, surface energy and the interlaminar shear strength of the composite (ILSS). Bisphenol A epoxy resin helps to improve fiber surface condition and improve fiber strand integrity. The ether emulsifier helps to reduce the fuzz weight and improve the splitting rate of the fiber. The vinyl ester resin can improve the strand integrity and hardness of the fiber. The rank of total surface energy is epoxy resin>ether emulsifier> vinyl ester resin. The rank of water absorption rate is epoxy resin<vinyl ester resin<ether emulsifier. The water absorption of different components in the sizing agent was not the main influencing factor on the interlaminar shear strength of the carbon fiber composite.

Key words: carbon fiber, sizing agent, surface properties, ILSS
