Modified carbon fiber, modified carbon graphite material and preparation method thereof
The invention discloses a modified carbon fiber, a modified carbon graphite material and a preparation method thereof.On one hand, carbon fiber loaded with copper particles is obtained through a unique modification method, and after high-temperature treatment, the copper particles are molten, spread and fused along the carbon fiber and coat the carbon fiber; a copper three-dimensional cross-linked network is formed in a matrix by utilizing the skeleton structure of the carbon fibers, the advantage of improving the conductivity of the matrix can be achieved, and in addition, the skeleton structure formed by the carbon fibers in the copper matrix also improves the mechanical strength and impact toughness of the matrix; on the other hand, the modified carbon fiber is introduced into the carbon material, the mechanical strength and the resistivity of the carbon material are greatly improved, and meanwhile, the carbon material does not need to be subjected to copper immersion, so that the production process is relatively simple, and the preparation period is shortened.
本发明公开了一种改性碳纤维、改性碳石墨材料及其制备方法，一方面通过独特改性方法获得了负载有铜颗粒的碳纤维，当经过高温处理后铜颗粒熔化，沿着碳纤维铺展和融并，并包覆碳纤维，利用碳纤维的骨架结构在基体中形成了铜三维交联网络，可起到提高基体导电性的优势，另外碳纤维在铜基体中形成的骨架结构，还提高了基体的力学强度以及抗冲击韧性；另一方面本发明还通过向碳材料中引入上述改性碳纤维，大幅度的提高了碳材料的力学强度，电阻率，同时上述碳材料由于不需要浸铜，因此生产工艺相对简单，缩短了制备周期。
