Ceramic matrix composite integrally-formed blade and preparation method thereof
The invention discloses a ceramic matrix composite integrally-formed blade and a preparation method thereof, and relates to the technical field of aero-engine preparation. The method comprises the following steps that fiber cloth is laid on the outer surface of a blade body mold, meanwhile, the fiber cloth is reserved at the two ends, and then the fiber cloth penetrates through the reserved fiber cloth and is laid; spreading the reserved fiber cloth on the outermost layer in a divergent manner, and circularly stacking; the fiber cloth forms an L-shaped laying layer along the mold, and the remaining reserved fiber cloth is flatly laid along the L-shaped laying layer; then, fiber cloth penetrates through the reserved fiber cloth and then is laid, and a U-shaped laying layer is formed; the stacking is cyclically carried out; suturing and fixing to obtain a blade preform; and carrying out subsequent treatment to obtain the ceramic matrix composite integrally formed blade. The integrally-formed laying layer structure is adopted, the complete fibers penetrate through the blade body, the blade crown and the edge plate and are sewn into a whole, so that the blade component can be integrally formed, the connection reliability problem between split parts is solved, and the overall reliability of the blade is improved.
本发明公开了一种陶瓷基复合材料整体成型叶片及其制备方法，涉及航空发动机制备技术领域。该方法包括以下步骤：将纤维布铺层在叶身模具的外表面，同时在两端预留纤维布，然后将纤维布穿过预留纤维布，并铺层；再将最外层的预留纤维布发散状平铺，循环层叠；将纤维布沿模具形成L型铺层，将剩余的预留纤维布沿L型铺层平铺；然后将纤维布穿过预留纤维布后铺层，形成U型铺层；以此循环层叠；进行缝合固定，得到叶片预制体；进行后续处理得到陶瓷基复合材料整体成型叶片。本发明采用整体成型铺层结构，设有完整纤维贯穿叶身、叶冠、缘板，并通过缝制形成一体，使得叶片构件可整体成型，解决了分体零件间的连接可靠性问题，提高了叶片整体可靠性。
