摘要/Abstract

摘要： 采用真空辅助RTM成型方法制备了0.5%碳纳米纤维(CNF)玻纤/环氧(GF/EP)复合材料,并对其一维饱和渗透率、不同温度下的力学性能、耐固体粒子冲蚀磨损性能进行了测试和研究分析。实验结果表明,加入0.5% CNF之后,平行于纤维方向的饱和渗透率降低了2~6倍,垂直于纤维方向的饱和渗透率降低了2~5倍;在孔隙率小于0.44时,两个方向的饱和渗透率差别不大,均接近于零;0.5% CNF的加入对纯EP及垂直于纤维方向复合材料的机械性能和耐固体粒子冲蚀磨损性能影响较小,在平行于纤维方向上复合材料的力学性能和耐固体粒子冲蚀磨损性能均有提高;在不同温度下,0.5% CNF的加入使垂直纤维方向上复合材料拉伸强度的稳定性得到提高。

Abstract: In this paper, vacuum assisted spray method was used to fabricate the Advantex glass fiber/epoxy composite with 0.5% CNF. The Advantex galss fiber/epoxy composite saturated permeability was measured by the unidirectional saturated flow method, and the mechanical properties at different temperatures and solid particle erosion resistance were measured and investigated. The results indicate that after adding 0.5% CNF, the parallel direction of the Advantex glass fiber saturated permeability decreased by 2~6 times, and the perpendicular direction of the fiber saturated permeability decreased by 2~5 times. When the porosity is less than 0.44, the saturated permeability of two direction had little difference, which are close to zero. The influence of 0.5% CNF on pure epoxy and perpendicular direction composite mechanical properties and solid particle resistance properties are much smaller than those of the parallel direction composite. At high temperature, the addition of the 0.5% CNF improves the stability of the tensile strength of perpendicular Advantex glass fiber/epoxy composite.

Key words: composite, CNF, sand erosion, tensile strength, flexural strength
