Continuous fiber toughened MAX phase ceramic matrix composite prepreg and preparation method thereof
The invention discloses a continuous fiber toughened MAX phase ceramic matrix composite prepreg and a preparation method thereof, and the preparation method comprises the following steps: mixing a dispersant, an adhesive and water to prepare a glue solution, and mixing the glue solution with MAX phase ceramic powder to obtain an MAX phase dispersion liquid; dipping continuous fibers in the MAX phase dispersion liquid, and applying pressure to promote permeation of the dispersion liquid to obtain a prepreg precursor; horizontally suspending and fixing the prepreg precursor by using a clamp, and respectively applying certain tension along the warp direction and the weft direction of the fiber to ensure the flatness of the prepreg precursor; and putting the clamp and the prepreg into a vacuum drying oven, and carrying out vacuum drying at a certain temperature to remove moisture, so as to obtain the continuous fiber toughened MAX phase ceramic matrix composite prepreg. The prepreg prepared by the invention has the advantages of good laying property, long storage life, low preparation cost, simple process, energy conservation, environmental protection and the like.
本发明公开了一种连续纤维增韧MAX相陶瓷基复合材料预浸料及其制备方法，包括以下步骤：将分散剂、粘合剂与水混合配制成胶液，将胶液和MAX相陶瓷粉末混合，得到MAX相分散液；将连续纤维浸渍于MAX相分散液中，并施加压力促进分散液的渗透，得到预浸料前驱体；将预浸料前驱体利用夹具使之水平悬空固定，并沿纤维经向与纬向分别施加一定张力，保证预浸料前驱体的平整；将夹具连同预浸料放入真空干燥箱在一定温度下真空干燥除去水分，得到连续纤维增韧MAX相陶瓷基复合材料预浸料。本发明制备的预浸料具有铺覆性好，储存期长，制备成本低，工艺简单，节能环保等优势。
