Wear resistance and thermal stability are not fundamental properties of materials, but their effects are inevitable in applications involving two-body contact because of friction-induced wear and heat. Wear resistance and thermal stability of epoxy containing 10% by weight of 66.34 μm aluminium particles were examined using mass loss per sliding distance approach and glass transition temperature ( T g ) was used as a parameter for thermal stability. The results obtained revealed a reduction in the wear rate due to addition of aluminium particles. About 62, 58 and 39% reductions at 9 N/0.65 m s −1 ; 9 N/1.3 m s −1 and 25 N/1.3 m s −1 , respectively imply that both sliding speed ( v ) and the applied load ( F ) contribute to an increase in the wear rate. A lower coefficient of friction of epoxy aluminium composites signifies lower surface wear rate in comparison with that of the epoxy polymer upon contact with another body in applications. The linear model establishes that v with a P value of 0.0046 has a greater significant influence on the wear resistance of the composite than F with a higher P value (0.0103). By the model, the epoxy aluminium composite under 24.63 N is expected to experience a wear rate of 0.000537 g m −1 which is 1380% lower than that established by the results of the experiment. About 36% increase in T g is observed and 2FI model affirms that there is a gradual increase in T g with heat flow through the sample during the glass transition period. Hence, the 2FI model having adequate precision of 164 > 4 is appropriate to be used for navigating a design phase for thermal stability properties.

铝微粒微复合材料的耐磨耐热性能

耐磨性和热稳定性不是材料的基本特性，但由于摩擦引起的磨损和热量，它们的影响在涉及两体接触的应用中是不可避免的。使用每滑动距离的质量损失方法检查含有 10% 重量百分比的 66.34 μm 铝颗粒的环氧树脂的耐磨性和热稳定性，并使用玻璃化转变温度 (T g ) 作为热稳定性参数。获得的结果表明，由于添加了铝颗粒，磨损率降低。在 9 N/0.65 m s -1 处减少约 62%、58% 和 39%；9 N/1.3 m s -1 和25 N/1.3 m s -1 分别意味着滑动速度（ v ）和施加的载荷（ F ）都有助于磨损率的增加。与环氧聚合物在应用中与另一物体接触时相比，环氧铝复合材料的较低摩擦系数意味着较低的表面磨损率。线性模型表明，P 值为 0.0046 的 v 对复合材料耐磨性的影响比具有较高 P 值 (0.0103) 的 F 更大。通过该模型，预计在 24.63 N 下的环氧铝复合材料的磨损率为 0.000537 g m -1，比实验结果确定的磨损率低 1380%。观察到约 36% 的 T g 增加，2FI 模型确认在玻璃化转变期间，随着热量流过样品，T g 逐渐增加。因此，2FI 模型具有足够的精度 164 >
