Preparation method of carbon fiber special-shaped body
The invention belongs to the technical field of carbon fiber net tires, and particularly relates to a preparation method of a carbon fiber special-shaped body. The preparation method comprises the following steps: mixing chopped carbon fibers, water and a dispersing agent, pouring the obtained mixed slurry into a mold, carrying out first vacuum-pumping treatment, applying a resin diluent to a suction filtration product in the mold, carrying out second vacuum-pumping treatment, and sequentially carrying out thermocuring, first carbonization and carbon deposition on a second suction filtration product obtained after demolding, so as to obtain the carbon fiber composite material. And carrying out dipping-carbonization and graphitization treatment to obtain the carbon fiber special-shaped body. The carbon fiber special-shaped body obtained by adopting a vacuum filtration mode has the characteristics of high strength, light weight, high density and long service life; meanwhile, vacuum filtration is adopted, and the preparation method is simple, easy to implement, high in efficiency, low in cost and suitable for application and popularization.
本发明属于碳纤维网胎技术领域，具体涉及一种碳纤维异形体的制备方法。本发明将短切碳纤维丝、水和分散剂混合，得到的混合浆料倒入模具中进行第一抽真空处理，将所述树脂稀释液施加于位于模具中的抽滤产物，进行第二抽真空处理，脱模后得到的第二抽滤产物依次进行热固化，第一碳化，碳沉积，浸渍‑碳化和石墨化处理，得到所述碳纤维异形体。本发明采用真空抽滤的方式所得碳纤维异形体具有强度大、质量轻、密度高、使用寿命长的特点；同时本发明采用真空抽滤，制备方法简单易行、效率高、成本低，适宜推广使用。
