An efficient strategy was developed to prepare the linear cylinder-like carbon fiber @ room temperature vulcanized silicone rubber (Cf@RTVSR) core-sheath elastomer as the high-performance additive of PRC with the purpose of improving the wear-resisting performance of phenolic resin composites (PRC). Results showed that the recovery of the modified PRC was improved by 27.14%. The friction coefficient of PRC modified by Cf@RTVSR core-sheath elastomer under the braking pressure of 0.5 MPa and the braking speed of 2000 rpm significantly rose to 0.3414 in contrast to unmodified one, while the wear rate dropped by 84.8% owing to the dense tribo-film forming on worn surfaces. The tribo-film had good scratch resistance without obvious stress concentration thereon, which was beneficial to reducing abrasive wear and the formation of fatigue cracks, thereby alleviating fatigue wear.

为了提高酚醛树脂的耐磨性能，制定了一种有效的策略来制备线性圆柱状碳纤维@室温硫化硅橡胶（Cf @ RTVSR）芯鞘弹性体作为PRC的高性能添加剂。复合材料（PRC）。结果表明，改性的PRC的回收率提高了27.14％。Cf @ RTVSR芯鞘弹性体在0.5 MPa的制动压力和2000 rpm的制动速度下改性的PRC的摩擦系数与未改性的相比明显提高到0.3414，而由于致密性，磨损率下降了84.8％。在磨损的表面上形成摩擦膜。摩擦膜具有良好的耐刮擦性，且应力不明显，有利于减少磨料磨损和疲劳裂纹的形成，
