Fiber-reinforced functional gradient layered ceramic-based composite material and preparation method and device thereof
The invention relates to the technical field of ceramic-based composite materials, in particular to a fiber-reinforced functional gradient layered ceramic-based composite material and a preparation method and device thereof.The preparation method comprises the following steps that a fiber preform is prepared, water-based ceramic slurry is prepared, the fiber preform is soaked with the water-based ceramic slurry, and then freeze drying is performed to obtain the fiber-reinforced functional gradient layered ceramic-based composite material. The preparation method comprises the following steps: putting a fiber-reinforced functional gradient layered ceramic matrix composite into a hot-pressing furnace, repeatedly carrying out impregnation and cracking for 3-6 times under a protective atmosphere, and carrying out hot-pressing treatment in the hot-pressing furnace to finally obtain the fiber-reinforced functional gradient layered ceramic matrix composite which comprises an outer compact layer and an inner loose layer. Through mixed use of a slurry process, a freeze-drying method, an impregnation and pyrolysis method and a hot-pressing auxiliary process, densification can be rapidly realized, meanwhile, the preparation period is shortened, the cost is also reduced, and meanwhile, the product quality is improved. The functional gradient layered fiber ceramic reinforced ceramic-based composite material is excellent in ablation resistance and light in weight while meeting the heat protection requirement.
本申请涉及陶瓷基复合材料技术领域，具体涉及一种纤维增强功能梯度层状陶瓷基复合材料及其制备方法、装置，包括以下步骤：制备纤维预制体，制备水基陶瓷浆料，将水基陶瓷浆料浸渍到纤维预制体中，后进行冷冻干燥，在保护气氛下反复进行3～6次浸渍裂解，再将其放入热压炉中进行热压处理，最终得到纤维增强功能梯度层状陶瓷基复合材料，该功能梯度层状纤维陶瓷增强陶瓷基复合材料包括外层致密层和内层疏松层。本申请通过料浆工艺、冷冻干燥法、浸渍裂解法以及热压辅助多种工艺的混合使用，能够快速实现致密化，同时，制备周期缩短、成本也得到了降低，同时，该功能梯度层状纤维陶瓷增强陶瓷基复合材料抗烧蚀能力优异且在满足防热需求的同时重量较轻。
