High-temperature composite material and method for producing high-temperature composite material
A method for preparing a carbon-carbon, carbon-ceramic matrix, or carbon-silica composite material, the method comprising melt processing a resin comprising a polyaryletherketone (PAEK) and at least one reinforcing additive to prepare a precursor part, pyrolyzing the precursor part to prepare a pyrolyzed part, impregnating the pyrolyzed part with a liquid second resin to prepare an impregnated part, and curing the impregnated part to obtain the carbon-carbon, carbon-ceramic matrix, or carbon-silica composite material. And pyrolyzing the impregnated component wherein during said pyrolysis, the temperature within the chamber increases one or more times at a rate of 1 DEG C/hour to about 20 DEG C/hour, and wherein optionally said pyrolysis is maintained at one or more temperatures for a period of time. Other methods include processing the oriented reinforcing additive and a resin comprising PAEK to prepare an oriented reinforcing additive PAEK, an oriented 1-2 dimensional sheet material, or an oriented 1-2 dimensional sheet material, thereby creating a fabric, prepreg or tape comprising the oriented reinforcing additive and impregnated PAEK. Other methods include impregnating a continuous fiber tape or fabric with a resin comprising PAEK and at least one reinforcing additive, or co-weaving a continuous fiber or fabric with PAEK fibers comprising PAEK and at least one reinforcing additive.
用于制备碳碳、碳陶瓷基体、或碳二氧化硅复合材料的方法，该方法包括对包含聚芳醚酮(PAEK)的树脂和至少一种增强添加剂进行熔融加工以制备前体部件，使前体部件热解以制备热解部件，将液体第二树脂浸注到热解部件中以制备浸注部件，以及使浸注部件热解，其中在所述热解期间，腔室内的温度以1℃/小时至约20℃/小时的速率升高一次或多次，并且其中任选地，所述热解在一个或多个温度下维持一段时间。其它方法包括加工定向增强添加剂以及包含PAEK的树脂以制备定向增强添加剂PAEK、定向1‑2维薄片材料、或定向1‑2维片状材料，从而创建包含定向增强添加剂和浸渍的PAEK的织物、预浸料或带。其它方法包括用包含PAEK的树脂和至少一种增强添加剂浸渍连续纤维带或织物，或者将连续纤维或织物与包含PAEK和至少一种增强添加剂的PAEK纤维共编织。
