日本研制成功了一种新型碳纤维强化碳化硅复合材料。这种新型复合材料具有相当高的弹性及可耐近1200℃的高温氧化性,气孔率可控制在20～70％的范围内。制取这种 Japan developed a new type of carbon fiber reinforced silicon carbide composite material. The new composite has a very high elasticity and resistance to high temperature oxidation of nearly 1200 ℃, the porosity can be controlled in the range of 20 to 70%. Preparation of this
