摘要:
为了增强碳纤维层合板的摩擦磨损性能,通过实验研究纳米SiC颗粒喷涂在碳纤维预浸料表面对碳纤维层合板摩擦磨损性能的影响。把纳米SiC分散在无水乙醇中,制备成浓度分别为0%、0.1%、0.5%、1%、3%、5%的纳米SiC溶液,均匀喷涂在碳纤维预浸料表面,固化成型,然后使用M-2000型环-块摩擦磨损试验机研究在90min、400r/min、200N的工况下层合板的摩擦磨损性能。实验结果表明:在碳纤维预浸料表面喷涂纳米SiC颗粒能够有效改善碳纤维层合板的摩擦磨损性能。当纳米SiC浓度为5%时,层合板的硬度最大;当纳米SiC浓度为1%时,层合板的摩擦系数、磨损量、磨痕的宽度及深度较于不含纳米SiC的试件分别降低52%,63%,32.3%,54.8%,摩擦磨损性能最好。

Abstract:
In order to enhance the friction and wear performance of carbon fiber laminates, the influence of nano-SiC particles sprayed on the surface of carbon fiber prepreg on the friction and wear performance of carbon fiber laminates was studied. Nano-SiC was dispersed in anhydride ethanol to prepare nano-SiC solution with concentration of 0%, 0.1%, 0.5%, 1%, 3% and 5%, and sprayed evenly on the surface of carbon fiber prepreg, then solidified and formed. The friction and wear performance of the lower composite plate under the working conditions of 90min, 400r/min and 200N was studied using m-2000 ring-block friction and wear testing machine. The experimental results show that spraying nano-SiC particles on the surface of carbon fiber prepreg can effectively improve the friction and wear performance of carbon fiber laminates. When the concentration of nano-SiC is 5%, the hardness of laminated plate is the greatest. When the concentration of nano-SiC is 1%, the friction coefficient, wear, width and depth of the laminates decrease by 52%, 63%, 32.3% and 54.8%, respectively, compared with that of the specimens without nano-SiC.
