Abstract

The invention discloses a preparation method of a fast-curing carbon fiber forging material. The fast-curing carbon fiber forging material is prepared from the following raw materials in percent by weight: 20%-80% of resin reinforcement body, 20%-80% of fast-curing resin, 0.5%-2% of filler and 1%-3% of additive. The preparation method of the fast-curing carbon fiber forging material comprises thefollowing steps: preparing a fast-curing resin matrix: fully mixing heat-latent fast-curing epoxy resin in a temperature range of 20-70 DEG C by a three-roll grinder for at least three times; and mixing according to the following mode: weighing chopped fibers and the resin matrix according to a proportion, enabling the chopped fibers and the resin matrix to be in contact, and then kneading for 1-6hours by a kneading machine under a heating condition of 20-70 DEG C, infiltrating fiber surfaces by the resin, and cooling to obtain the fast-curing carbon fiber forging material. The preparation method disclosed by the invention is very suitable for composite material products with complex geometrical shapes; the production efficiency can be improved; the processes of material cutting, materialoverlapping and the like of traditional continuous fibers are omitted; fiber distribution is similar to isotropy; the property is more stable; convenience is brought for size processing such as punching; and the property reproducibility is stronger.
