Method for connecting ceramic matrix composite material and metal material
The invention belongs to the technical field of material connection, and discloses a method for connecting a ceramic-based composite material and a metal material, which comprises the following steps: continuously weaving in a three-dimensional weaving manner to obtain a ceramic-based composite material fiber preform, and pre-burying a plurality of nickel-based high-temperature alloy screws in the ceramic-based composite material fiber preform; preparing a composite material interface phase and a ceramic matrix phase of the ceramic-based composite material fiber preform by adopting a chemical vapor infiltration method to obtain a ceramic-based composite material; threads are machined on screw rods of the nickel-based high-temperature alloy screws, and a plurality of bolt holes corresponding to the nickel-based high-temperature alloy screws are formed in the pre-connected metal materials; the metal material is assembled on a plurality of nickel-based high-temperature alloy screws, nuts are arranged on the nickel-based high-temperature alloy screws in a sleeving mode, and the metal material and the ceramic-based composite material are fastened by rotating the nuts. And under the condition that the mechanical properties of the two materials are not damaged, the bonding performance is high, the application range is wide, the process is simple, and the stability is high.
本发明属于材料连接技术领域，公开了一种陶瓷基复合材料与金属材料的连接方法，包括：采用三维编织方式连续编织得到陶瓷基复合材料纤维预制体，并在陶瓷基复合材料纤维预制体内预埋若干镍基高温合金螺钉；采用化学气相渗透方法制备陶瓷基复合材料纤维预制体的复合材料界面相及陶瓷基体相，得到陶瓷基复合材料；在各镍基高温合金螺钉的螺杆上加工螺纹，并在预连接的金属材料上开设与若干镍基高温合金螺钉对应的若干螺栓孔；将金属材料装配在若干镍基高温合金螺钉，并在镍基高温合金螺钉上套设置螺母，以及通过旋转螺母紧固金属材料和陶瓷基复合材料。在不损伤两种材料的力学性能的情况下，结合性能强，适用范围广，工序简单，稳定性高。
