SiO_2-竹纤维协同改性对环氧树脂基复合材料摩擦磨损性能的影响
|
摘要
为了提高环氧树脂(EP)基复合材料的摩擦磨损性能,制备低成本耐磨材料,选用纳米SiO_2粒子和竹纤维(BF)等作为填料,制备了纳米SiO_2-BF/EP复合材料。通过摩擦磨损测试仪、动态热机械分析仪和SEM研究了纳米粒子和纤维对复合材料的耐磨性能、热学性能及微观结构的影响。研究结果表明:单独加入BF后,BF/EP复合材料的体积磨损较同条件下的纯EP大幅度降低,最多可降低71%;同时加入SiO_2纳米粒子和BF后,对纳米SiO_2-BF/EP复合材料的玻璃化转变温度和体积磨损影响显著,玻璃化转变温度比纯EP提高了11℃,达到了124℃,体积磨损较同条件下的纯EP下降了约75.3%。
In order to improve the friction and wear properties of epoxy resin(EP)matrix composites and prepare low-cost EP wear resistant materials,nano SiO_2 particles and bamboo fibers(BF)were used as fillers to prepare nano SiO_2-BF/EP composites.The friction and wear tester,dynamic thermomechanical analyzer and SEM were used to study the effect of nanoparticles and fibers on the wear resistance,thermodynamic properties and microstructure of the composites.The results show that after adding BF alone,the volumetric wear of BF/EP composite is significantly reduced by 71% compared with the pure EP under the same conditions;At the same time,the addition of nano SiO_2 and BF has a significant effect on the glass transition temperature and wear volume of nano SiO_2-BF/EP composite.The glass transition temperature is 11℃ higher than that of the pure EP,reaching 124℃.The volumetric wear is about 75.3%lower than that of the pure EP under the same conditions.
