用国产标准型硅酸铝纤维作增强体，利用真空过滤成型法制成纤维预制体，采用液态模锻制成局部增强第一道环槽的内燃机活塞。所得复合材料力学性能比ZL109铝合金有较大提高，其中耐磨性增加最为显著。复合材料活塞的主要性能满足内燃机活塞性能标准。
The domestic standard aluminum silicate fiber is used as a reinforcing body, the fiber preform is made by the vacuum filtration forming method, and the piston of the internal combustion engine locally reinforced by the first ring groove is made by liquid die forging. The mechanical properties of the resulting composite ZL109 aluminum alloy has greatly improved, including the most significant increase in wear resistance. The main performance of composite piston piston engine performance standards to meet.
