为了改善芳纶浆粕的力学性能和湿摩擦性能，采用过滤法制备了含0 wt%(F0)、0.5 wt%(F1)和1 wt%(F2)芳纶浆粕的碳纤维/酚醛复合材料。随后，对其三维表面轮廓、骨密度、孔隙率和压缩模数进行了表征。结果表明，芳纶浆粕的桥联和增强作用可显著提高界面粘结性能。剪切强度和拉伸强度随着芳纶浆粕含量的增加而增大，F2的剪切强度和拉伸强度分别为1.23 Mpa和85.19 Mpa，比F0分别提高31%和54%。芳纶浆粕的加入增加了摩擦系数，降低了磨损率。(C)2016爱思唯尔有限公司。保留所有权利。
To improve the mechanical and wet tribological properties, the carbon fabric/phenolic composites containing 0 wt% (F0), 0.5 wt% (F1) and 1 wt% (F2) aramid pulp were prepared by filtration method. Subsequently, their three-dimensional surface profiles, skeletal densities, porosities and compression modules were characterized. Results show that the bridging and strengthening effects of aramid pulp can dramatically enhance the interfacial bonding. The shear and tensile strengths increase with the rise of aramid pulp content and that of F2 are 1.23 MPa and 85.19 MPa, improved by 31% and 54% compared with F0. The incorporation of aramid pulp increases the friction coefficient and decreases the wear rate. (C) 2016 Elsevier Ltd. All rights reserved.
