Ceramic matrix composite material rotor blade fiber preform and manufacturing method thereof
The invention discloses a ceramic matrix composite material rotor blade fiber prefabricated body and a manufacturing method, the rotor blade fiber prefabricated body comprises a blade body, an edge plate and a tenon which are connected into a whole and formed by overlapping and laying a plurality of fiber laying layers, the fiber laying layers are made of SiC fiber cloth, and the tenon comprises a main body part; the main body part comprises two opposite tenon end faces and two tenon side faces adjacent to the two tenon end faces, the edges of the two sides of the fiber laying layer correspond to the two tenon end faces respectively, the tenon side faces are acting faces of the tenon, and the two acting faces are suitable for making contact with the two inner side walls of the mortise respectively. And the inclination angle of each acting surface is suitable for being the same as the inclination angle of the corresponding inner side wall. Thus, after the rotor blade fiber prefabricated body is manufactured, chamfering treatment is conducted on the two sides of the bottom of the main body part, a finished product tenon can be obtained, it can be guaranteed that the fiber laying layer on the acting face is continuous, the excellent performance of the ceramic matrix composite material is fully played, and the bearing capacity of the tenon and the bearing capacity of the rotor blade are improved.
本发明公开了一种陶瓷基复合材料转子叶片纤维预制体及制作方法，转子叶片纤维预制体包括连接为一体且由多层纤维铺层重叠铺设形成的叶身、缘板和榫头，纤维铺层由SiC纤维布制成，榫头包括主体部，主体部包括相对的两榫头端面、以及均与两榫头端面相邻接的两榫头侧面，纤维铺层的两侧边缘分别对应两榫头端面，榫头侧面为榫头的作用面，两作用面适于分别与榫槽的两内侧壁相接触，且各作用面的倾斜角度适于与对应的内侧壁的倾斜角度相同。这样一来，制得转子叶片纤维预制体后，在主体部的底部两侧进行倒角处理，即可得到成品榫头，可保证作用面处的纤维铺层是连续的，充分发挥陶瓷基复合材料的优良性能，提高榫头的承载能力和转子叶片的承载能力。
