技术领域
本发明涉及复合材料领域，具体涉及一种碳纤维增强陶瓷基复合材料及其制备方法。
背景技术
随着新型发动机的研制和新概念航天运载器的发展，对高温结构材料提出了更高的要求。纤维增强陶瓷基复合材料因在高温下具有高强度、高韧性、耐高温、抗腐蚀性好和低密度等优良性能，在战略武器和空间技术等领域具有广泛的应用前景，近年来越来越受到材料工作者的重视。
陶瓷材料具有良好的高温强度、高温稳定性和高温抗氧化能力，但由于其分子结构的键合特点，缺乏塑性变形能力，表现为脆性，严重影响了其作为结构材料的应用。碳纤维拥有良好的高温力学性能和热性能，在惰性环境中超过2000℃仍能保持其力学性能不降低。用碳纤维增强陶瓷，材料在断裂过程中通过裂纹偏转、纤维断裂和纤维拔出等机理吸收能量，既增强了材料的强度和韧性，又保持了陶瓷良好的高温性能。其中，应用最广泛的碳纤维增强碳化硅复合材料缺点在于：碳纤维与碳化硅基体热膨胀匹配不够理想，碳化硅基体制备过程存在脱落裂纹等缺陷，影响复合材料的力学性能和热性能，制约了复合材料的发展。
发明内容

本发明另一方面提供一种碳纤维增强陶瓷基复合材料的制备方法，包括如下步骤：
(1)将碳纤维织物置于密闭容器中，抽真空后吸入酚醛树脂/酒精溶液，直至浸没织物；浸泡后取出，样品转移至高压釜中，升温并抽真空维持0.5～1h后加1～3MPa气压，保持1～2h后再升温150～180℃进行预固化，之后升温至190～230℃进行后固化，然后将样品置于900～1200℃氮气气氛下中裂解2～4h，获得热解碳层；
(2)再将试样置于密闭容器中，抽真空后吸入60～90℃的聚碳硅烷/乙烯基苯溶液，浸没编织物，浸泡后取出，样品转移至高压釜中升温，抽真空0.5～1h后，加1～3MPa气压1～2h，并升温至150～200℃进行固化4～8h，然后将样品置于1100～1300℃氮气气氛下裂解2～4h，获得热解碳化硅层；
(3)再将试样置于密闭容器中，抽真空后吸入钛酸脂/醇类溶液，浸没编织物，浸泡后取出，样品转移至高压釜中升温，抽真空0.5～1h后，加1～3MPa气压1～2h，并升温至150～200℃进行固化2～4h，然后将样品置于700～900℃氮气气氛下裂解2～3h；
(4)依次重复步骤(1)和(2)各2～5次；
(5)重复步骤(3)1～2次，获得复合材料。
进一步的，所述钛酸脂为钛酸四丁脂、钛酸四乙脂、钛酸乙脂、钛酸四异丙脂中的一种或几种的混合物。
采用上述本发明技术方案的有益效果是：
本方法在碳纤维表面制备热解碳，缓解碳纤维和陶瓷基体之间热膨胀系数的差异；在碳化硅层外表面制备氧化钛，氧化钛在高温时为熔融状态，填充碳化硅裂纹等缺陷，增加了基体的致密性；基体的最外层设置氧化钛，氧分子在氧化钛中的扩散速率非常低，进一步提高了抗氧化性能。
