一种碳纤维增强型碳化硅基机械密封材料及其制造方法
摘要：
一种碳纤维增强型碳化硅基机械密封材料及其制造方法。所述的方法是将适宜长度的碳纤维、酚醛树脂、碳化硅粉末、六次甲基四胺、添加剂及稀释剂按一定比例置于混合器中，于30-50℃的温度下混合均匀后装入压模内，热压成型温度为30-80℃，加压到适宜压力时升温至120-180℃，保温固化5-10分钟。采用所述的方法可以制造耐脆裂或耐碎裂的碳化硅基机械密封材料。
摘要（英）：

A carbon fiber reinforced type silicon carbide based mechanical seal material, and a manufacturing method of the material, are provided. According to the provided method, carbon fiber in proper length, phenolic resin, silicon carbide powder, hexamethylenetetramine, an additive and a diluent are mixed in a mixer according to a certain ratio, mixed uniformly at the temperature of 30 DEG C to 50 DEG C, disposed in a press mould, pressurized to a proper pressure at the hot-pressing molding temperature of 30 DEG C to 80 DEG C, heated to 120 DEG C to 180 DEG C, and cured at the temperature for 5minutes to 10minutes. The brittle rupture resistant or fragmentation resistant silicon carbide mechanical seal materials can be manufactured by the above method.
