Preparation method of reduced graphene oxide-chopped carbon fiber reinforced carbon-based composite material
The invention discloses a preparation method of a reduced graphene oxide-short carbon fiber reinforced carbon-based composite material. The carbon-based composite material is prepared from a hybrid porous network skeleton preform formed by mutual crosslinking of reduced graphene oxide and functionalized short carbon fibers through composite pyrolytic carbon. The preparation method comprises the following steps: constructing a hybrid preform of reduced graphene oxide (rGO) and short carbon fibers by adopting a hydrothermal process to form a cross-linked porous network hybrid structure, and densifying a pyrolytic carbon matrix by taking the hybrid preform as a preform and utilizing a chemical vapor infiltration process, so as to prepare the reduced graphene oxide-short carbon fiber reinforced carbon-based (rGO-CCFs/C) composite material. According to the present invention, the reduced graphene oxide rGO and the short carbon fibers are mutually crosslinked to form the skeleton, such that the carbon matrix far away from the carbon fibers can be reinforced, the multi-scale full-region reinforcement of the carbon matrix is achieved, and the problem that the carbon matrix far away from the carbon fibers in the traditional short carbon fiber reinforced carbon matrix cannot be effectively reinforced is solved;
本发明公开一种还原氧化石墨烯‑短切碳纤维增强碳基复合材料的制备方法，所述碳基复合材料由还原氧化石墨烯与官能团化的短切碳纤维相互交联形成的杂化多孔网络骨架预制体通过复合热解碳制备；先采用水热工艺构筑还原氧化石墨烯rGO与短切碳纤维的杂化预制体以形成相互交联的多孔网络杂化结构，再以其为预制体利用化学气相渗透工艺致密化热解碳基体，从而制备出还原氧化石墨烯‑短切碳纤维增强碳基(rGO‑CCFs/C)复合材料。还原氧化石墨烯rGO与短切碳纤维相互交联形成骨架，可增强远离碳纤维的碳基体，实现了碳基体的多尺度全区域增强，克服了传统短切碳纤维增强碳基体中远离碳纤维碳基体不能得到有效增强的问题。
