Carbon fibers reinforced lithium aluminosilicate matrix composites (C_f/LAS) were prepared by slurry infiltration combined with a hot press procedure. The friction, wear behavior, and wear mechanisms of C_f/LAS composites under dry sliding conditions were investigated. The results show that the coefficient of friction (COF) initially increased with the increase in carbon fiber content, and reached the maximum value of 0.20 for the 33%C_f/LAS composite. The COF increased sharply with increasing sample temperature from RT to 300 °C. The COF remained stable in the temperature range of 300–500 °C. The two wear mechanisms of LAS glassceramics are fatigue wear and abrasive wear. The C_f/LAS composites demonstrate slight spalling and shallow scratches. These results show that carbon fibers improve the mechanical properties and wear resistance of C_f/LAS composites.

碳纤维增强铝硅酸锂复合材料在GCr15钢上滑动的摩擦磨损性能

碳纤维增强的铝硅酸锂基复合材料（C _f / LAS）通过浆料浸渗结合热压工艺制备。研究了C _f / LAS复合材料在干滑条件下的摩擦，磨损行为和磨损机理。结果表明，摩擦系数（COF）最初随着碳纤维含量的增加而增加，并在33％C _f / LAS复合材料中达到最大值0.20 。随着样品温度从RT升高到300°C，COF急剧增加。COF在300–500°C的温度范围内保持稳定。LAS玻璃陶瓷的两种磨损机理是疲劳磨损和磨料磨损。的C _˚F/ LAS复合材料显示出轻微剥落和浅划痕。这些结果表明碳纤维改善了C _f / LAS复合材料的机械性能和耐磨性。
