Method for efficiently preparing continuous fiber reinforced silicon carbide ceramic-based composite material
The invention discloses a method for efficiently preparing a continuous fiber reinforced silicon carbide ceramic matrix composite material. The method comprises the following steps: 1, preparing a resin matrix; 2, preparing a resin-based composite material; 3, performing carbonizing; 4, carrying out in-situ infiltration reaction. The continuous fiber reinforced carbon-rich resin-based composite material is prepared from the mature and efficient resin-based composite material, the efficiency is high, and the cost is low; the in-situ cracking-infiltration reaction is adopted, the monatomic silicon powder is coated with excessive cracking carbon, the reaction degree is effectively controlled, the damage risk of silicon to continuous fibers is reduced, the comprehensive performance of the continuous fiber reinforced silicon carbide ceramic-based composite material is greatly improved, and the advantages of high efficiency and high compactness of a traditional infiltration method are reserved. The preparation efficiency of the continuous fiber reinforced silicon carbide ceramic-based composite material can be greatly improved by adopting a process of mature resin-based composite material preparation and in-situ infiltration reaction.
本发明公开了一种高效制备连续纤维增强碳化硅陶瓷基复合材料的方法，包括以下步骤：步骤一：树脂基体配置；步骤二：树脂基复合材料制备；步骤三：碳化；步骤四：原位熔渗反应。本发明中采用成熟、高效树脂基复合材料制备连续纤维增强富碳树脂基复合材料，效率高、成本低；本发明中采用原位裂解‑熔渗反应，通过过量裂解碳包覆单质硅粉，有效控制反应程度，降低了硅对连续纤维的损伤风险，大幅提高了连续纤维增强碳化硅陶瓷基复合材料的综合性能且保留传统熔渗法的高效、高致密的优势。本发明中采用成熟树脂基复合材料制备+原位熔渗反应的工艺，可大幅提升连续纤维增强碳化硅陶瓷基复合材料制备效率。
