Embodiment 1
[0039] (1) First prepare the dispersion, the weight ratio of the dispersant polyethylene oxide, methyl hydroxypropyl cellulose ether and distilled water in the dispersion is 1:1:2000, and then add short carbon fibers with a length of 6mm to the dispersion Among them, the weight ratio of the two is 1:400, wherein the weight of the short carbon fiber is 9g, and finally the above-mentioned mixture is stirred in a magnetic stirrer for 8h to evenly disperse the short carbon fiber in the dispersion liquid, and the stirring speed is 800 rpm;
[0040] (2) Pour the above mixture into a container with a certain geometric shape, the geometric shape of the container is determined according to the shape of the prefabricated body, let the short carbon fibers settle for 0.5h, and suck out the supernatant;
[0041] (3) Place the above-mentioned container in a drying oven, and dry it at 110° C. for 10 hours to obtain 8.79 g of a preformed short carbon fiber preform;
[0042] (4) In 200g of n-p...
