摘　　要：为了提升篮球鞋用碳纤维复合材料的使用性能,对碳纤维进行了表面改性处理并考察了NiOH改性时间对碳纤维复合材料润湿性能和力学性能的影响。结果表明,以尿素为沉淀剂可制备表面性能良好的NiOH改性碳纤维。在介质为水和二碘甲烷时,改性碳纤维的接触角和表面能分别低于和高于未改性碳纤维,表面改性时间越长则改性碳纤维的接触角越小、表面能越大。改性碳纤维复合材料的弯曲强度W_(q)和弯曲模量W_(m)都高于未改性碳纤维复合材料,改性时间越长则W_(q)和W_(m)先增后减,最大值在改性时间为3 h时取得,之后继续增加碳纤维的改性时间,材料的W_(m)反而会降低。对碳纤维进行改性的适宜时间为3 h,此时改性碳纤维复合材料具有良好的W_(q)和W_(m)。In order to improve the performance of carbon fiber composites for basketball shoes,the surface modification of carbon fibers was carried out,and the effects of NiOH modification time on the wetting properties and mechanical properties of carbon fiber composites were investigated.The results showed that NiOH modified carbon fibers with good surface properties could be prepared by using urea as precipitant.When the medium was water and diiodomethane,the contact angle and surface energy of the modified carbon fiber were lower and higher than that of the unmodified carbon fiber,respectively,and the longer the surface modification time,the smaller the contact angle and the greater the surface energy of the modified carbon fiber.The flexural strength W_(q) and flexural modulus W_(m) of the modified carbon fiber composites were higher than those of the unmodified carbon fiber composites,and the longer the modification time,the W_(q) and W_(m) increased first and then decreased,and the maximum value was obtained when the modification time was 3 h,and then the modification time of the carbon fiber was increased,and the W_(m) of the material decreased.The suitable time for modifying carbon fiber was 3 h,and the modified carbon fiber composite had good W_(q) and W_(m).
