摘要/Abstract

摘要： 本文研究了不同温度下RIM145树脂的粘度和适用期,分析了不同温度下RIM145树脂和碳纤维单丝之间的浸润性;并以碳纤维单向布为增强材料,采用真空辅助灌注成型工艺制备了碳纤维增强环氧树脂(CF/EP)复合材料,研究了复合材料的力学性能,对层间剪切试样剖断面形貌进行了SEM分析,并研究了使用VAP单向透气膜辅助真空灌注成型工艺对CF/EP复合材料厚制件灌注质量的影响。研究结果表明,RIM145 树脂基体在50 ~ 70℃粘度低、适用期长且树脂与碳纤维单丝之间的浸润性良好,适用于CF/EP复合材料的真空辅助灌注成型工艺;灌注的CF/EP具有良好的力学性能,树脂和纤维具有中等粘结强度界面,采用VAP单向透气膜辅助真空辅助灌注成型工艺可降低CF/EP复合材料的孔隙率。

Abstract: The viscosity and pot life of RIM145 resin at different temperatures were studied and the wettability between carbon fiber and RIM145 resin under varied temperatures were also analyzed. Using RIM145 rein as the matrix and UD carbon fabric as the reinforcement, carbon fiber reinforced epoxy resin (CF/EP) composites were prepared by the vacuum assisted resin transfer molding (VARTM) process. The mechanical properties of the CF/EP composites were investigated and SEM morphology of the fracture and slip surface of the sample used for interlaminar shear strength testing were observed. The research results showed that the RIM145 resin matrix had a series of characteristic performance such as low-viscosity, a long-working life and good-wettablity with carbon fiber filament at 50 ~ 70℃, was suitable for VARTM process. The prepared CF/EP composites had excellent mechanical performance and middle-level bonding performance interface.The porosity of the CF/EP composites can be lowered by assisting the VARTM process using VAP membrane.
