Carbon fiber reinforced composite material and preparation method thereof
The invention relates to the field of carbon fiber composite material processing, and provides a carbon fiber reinforced composite material and a preparation method thereof.The preparation method of the carbon fiber reinforced composite material comprises the steps that 1, metakaolin is prepared; step 2, preparation of a hafnium carbide modified nano carbon fiber pad: polyacrylonitrile and hafnium carbide decorative polyacrylonitrile yarns are prepared by winding 1-3mm nano fiber strips, then carbonization is performed, and the hafnium carbide modified nano carbon fiber pad is obtained after carbonization; 3, 45-60 parts of metakaolin and 4-10 parts of aluminum oxide powder are pre-dispersed and mixed and then stacked with 5-8 g of hafnium carbide modified nanometer carbon fiber pads, a multi-layer system is formed, all layers are poured into a graphite mold lined with graphite flakes according to the stacking sequence, after pressing is conducted, the structure is consolidated through spark plasma sintering, and the carbon fiber reinforced composite material is formed. The problems of strengthening and toughening the composite material by the carbon fiber, improving various mechanical properties and enabling the composite material to maintain higher mechanical integrity can be solved.
本申请涉及碳纤维复合材料加工领域，提供了一种碳纤维增强复合材料以及制备方法，碳纤维增强复合材料制备方法包括：步骤一：偏高岭土的制备；步骤二：碳化铪修饰纳米碳纤维垫的制备：聚丙烯腈和碳化铪装饰聚丙烯腈纱线通过缠绕1‑3mm的纳米纤维条制备，随后进行碳化，碳化后得到碳化铪修饰的纳米碳纤维垫；步骤三：将45‑60份偏高岭土、4‑10份氧化铝粉体预分散混合后与5‑8g碳化铪修饰的纳米碳纤维垫层叠，形成一个多层体系，按层叠顺序将每层倒入内衬石墨片的石墨模具中，进行压制后，通过火花等离子烧结巩固结构，形成碳纤维增强复合材料，可以解决碳纤维对复合材料的强韧化，提高各方面力学性能，使复合材料保持更高的机械完整性的问题。
