一、引言本文研讨炭材作为内燃式发动机的活塞材料应用。炭材是指高强度石墨材料而不是纤维补强材料。目前活塞通常是由铝基合金制成的系列产品,但铝基合金材料有高热膨胀系数和温度超过200℃时强度迅速降低的缺点。炭材料能避免这些缺点,此外还有较低密度。

I. INTRODUCTION This paper discusses the application of carbonaceous materials as piston materials for internal combustion engines. Carbon material refers to high-strength graphite material rather than fiber reinforcement. At present the piston is usually a series of products made of aluminum-based alloy, but the aluminum-based alloy material has the disadvantage of high thermal expansion coefficient and rapid decrease of strength when the temperature exceeds 200 ° C. Carbon materials avoid these disadvantages, in addition to lower densities.
