Grid type ceramic-based wave-absorbing composite material as well as preparation method and application thereof
The invention discloses a grating type ceramic-based wave-absorbing composite material as well as a preparation method and application thereof, and relates to the technical field of wave-absorbing materials. Comprising a grid structure formed by crisscrossing a plurality of ceramic-based composite flat plates; each ceramic-based composite flat plate is a cuboid; a plurality of grooves are equidistantly formed in one side of each ceramic-based composite flat plate along the long edge direction; when a plurality of ceramic-based composite flat plates are crisscrossed, the grooves in the longitudinal ceramic-based composite flat plates and the grooves in the transverse ceramic-based composite flat plates are embedded into each other to form an interlocking grating structure. The prepared wave-absorbing material with the grating structure has good high temperature resistance, and meanwhile excellent room-temperature and high-temperature wave-absorbing performance can be achieved through the material design of fibers, an interface and a matrix and the grating structure design.
本发明公开了一种格栅型陶瓷基吸波复合材料及其制备方法和应用，涉及吸波材料技术领域。包括多个陶瓷基复合平板通过纵横交错形成的格栅结构；每个陶瓷基复合平板为长方体；每个陶瓷基复合平板沿长边方向在其一侧均等距开设有多个凹槽；多个陶瓷基复合平板纵横交错时，其纵向的陶瓷基复合平板上的凹槽，与横向的陶瓷基复合平板上的凹槽，互相嵌入其中，形成互锁的格栅结构。本发明所制备的格栅结构吸波材料具有良好的耐高温性，同时可通过纤维、界面、基体的材料设计以及格栅结构设计实现优异的室温和高温吸波性能。
