Superior wear resistance of boron phenolic resin-based composites using fluorine rubber micro powder as high-performance additive

In this work, fluorine rubber micro powder (FMP) was successfully introduced into boron phenolic resin (BPF)-based composites, forming FMP/BPF double-component matrix. The results showed FMPs led to the change of fracture mode and resisted permanent deformation of composites. When FMPs contents were 10 wt%, better friction coefficient stability (Cv(μ) = 2.91) were obtained and the torque curve (αT/% = 0.90) became more flat due to the unchangeable actual contact area caused by the uniform deformation of composites with evenly-distributed FMPs during every braking process. The wear rate of modified composites was reduced by 80.9% owing to the reduction of fatigue wear and the formation of large-area friction film. FMP/BPF could significantly enhance wear resistance of composites for enlarging the applications in machinery and equipment. •Effect of FMP as additive for BPF-based composites were investigated.•FMP/BPF-based composites showed significantly lower wear rate.•Superior wear resistance of composites was related to reduction of fatigue wear.
