通过添加质量分数为4％~12％的改性矾土，并减少酚醛树脂的添加量制备了树脂基复合摩擦材料，研究了树脂基复合摩擦材料的力学性能、抗热衰退性能及摩擦磨损性能。结果表明：添加质量分数为8％的改性矾土时，摩擦材料的硬度、弯曲强度、冲击韧性略有降低，但仍处于较高的水平，但材料的摩擦因数增幅较大，高温抗热衰退系数较未添加改性矾土试样的提高近12％，表现出良好的抗热衰退性能。
By adding modified bauxite by 4%-1 2% (mass fraction)and reducing the addition of phenolic resin,resin-based composite friction materials were prepared,and the mechanical properties,anti-fade properties and friction and wear properties of the resin-based composite friction materials were studied.Experimental results show that,after adding 8%(mass fraction)modified bauxite,hardness,flexural strength and impact toughness of the composite decreased slightly,but still in the high level,and friction coefficient increased considerably.The high temperature anti-fade coefficient of the composite friction materials increased by nearly 1 2% than the material without modified bauxite,and they exhibited better anti-fade properties.
