Continuous fiber interwoven laminated zirconium diboride-based composite material and preparation method thereof
The invention belongs to the field of ultrahigh-temperature ceramic-based composite materials, and particularly relates to a continuous fiber interwoven laminated zirconium diboride-based composite material and a preparation method thereof. By utilizing the characteristic that the polyether sulfone-zirconium diboride-based ceramic slurry is converted into a solid state from a liquid state when meeting water, the continuous fiber impregnated with the polyether sulfone zirconium diboride-based ceramic slurry is put into the water to be cured and then is subjected to cold pressing to form continuous fiber single-layer plates; and then the continuous fiber single-layer plates are sequentially laid at the angles of 0 degree, 45 degrees, 90 degrees and -45 degrees to prepare a unit laminated plate, a plurality of unit laminated plates are stacked to prepare a pre-sintered blank, and finally the continuous fiber interwoven laminated zirconium diboride-based composite material is prepared through hot pressed sintering. The material has the beneficial effects that the prepared composite material has low porosity, high strength and excellent fracture resistance, thermal shock resistance andoxidation resistance, the method is simple and controllable to operate, and large-scale production is easy to realize.
本发明属于超高温陶瓷基复合材料领域，具体涉及一种连续纤维交织层合二硼化锆基复合材料及其制备方法，利用聚醚砜‑二硼化锆基陶瓷浆料遇水由液态转变为固态的特性将浸渍聚醚砜‑二硼化锆基陶瓷浆料后的连续纤维投入水中固化后再经过冷压制成连续纤维单层板，然后将连续纤维单层板先后以0°、45°、90°、‑45°的角度铺层制得一个单元层合板，多个单元层合板堆叠制得预烧结坯体，最后通过热压烧结制备出一种连续纤维交织层合二硼化锆基复合材料。本发明的效果和益处：制备出的复合材料具有低孔隙率、高强度以及优良的抗断裂性能、抗热冲击性能和抗氧化性能，并且方法操作简单可控，易于实现规模化生产。
