Chopped fiber carbon fiber composite material and preparation method thereof
The invention relates to a chopped fiber carbon fiber composite material and a preparation method thereof, and belongs to the technical field of carbon fiber composite material preparation. The preparation method comprises the following steps: 1, grinding a carbon fiber raw material; 2, carrying out short fiber deposition molding; 3, carrying out resin impregnation; 4, forming a mold and injectingliquid, namely putting the resin-infiltrated fiber blank into the mold for forming the mold, and injecting a potential mesophase pitch liquid at the same time; 5, performing high-pressure forming heat treatment: subjecting the infiltrated fiber blank containing the asphalt liquid to heat treatment under high pressure and then condensing the fiber blank to obtain a cured blank; 6, carbonization heat treatment: demolding the cured blank body and then carbonizing to obtain a carbonized blank body; and 7, high-temperature graphitization: carrying out high-temperature graphitization treatment on the carbonized blank to obtain the finished product carbon fiber composite material. The chopped fiber carbon fiber composite material prepared by the invention has high purity and greatly improved compression strength and bending strength, solves the problem of corner solid waste, realizes recycling of the material and generates good economic benefits.
本发明涉及一种短切纤维碳纤维复合材料及其制备方法，属于碳纤维复合材料制备技术领域，包括以下步骤：步骤一碳纤维原料磨碎；步骤二短纤维沉积成型；步骤三树脂浸渍；步骤四成模注液，将树脂浸润纤维胚体放入模具成模，同时注入潜在中间相沥青液；步骤五高压成型热处理，将含有沥青液的浸润纤维胚体在高压下热处理后冷凝获得固化胚体；步骤六碳化热处理，将固化胚体脱模后碳化处理获得碳化胚体；步骤七高温石墨化处理，将碳化胚体高温石墨化处理获得成品碳纤维复合材料；本发明制备的短切纤维碳纤维复合材料，具有较高的纯度同时抗压、抗弯强度大幅度提高，解决了边角固废问题，同时实现了材料的回收利用，产生较好的经济效益。
