The sum of the mass percentages of the components is 100 percent by adjusting the mixture ratio; for example, 60% by mass of carbon fiber, 30% by mass of epoxy A glue resin and 10% by mass of epoxy B glue resin are weighed; weighing 50% of carbon fiber, 35% of epoxy A glue resin and 15% of epoxy B glue resin by mass; because the carbon fiber has light weight, high strength and good aging resistance, the composite material using the carbon fiber as the matrix also has the advantages of light weight, high strength and good aging resistance.

For example, when the mold is used for the first time, the mold is subjected to a release agent coating and dry curing treatment; or the release agent is stripped from the surface of the mold due to long service time, the mold with the surface not covered by the release agent is not covered, and the coating and the drying treatment of the release agent are carried out again.

207. And cooling the mold to a second temperature, and maintaining the mold at the second temperature and the first pressure for a second time to obtain the carbon fiber composite material.
After the epoxy resin in the first mixture reacts at a high temperature, the crosslinking reaction speed is reduced, in order to improve the crosslinking degree of the epoxy resin, the temperature can be reduced and the reaction time can be prolonged, the crosslinking degree of the crosslinking reaction is not enough, and the crosslinking curing reaction needs to be continued; and continuously reacting for a second time at a second temperature, wherein the set second time is longer than the first time, and the second time is set to be long enough, so that the carbon fiber composite material with higher crosslinking degree can be obtained.
More preferably, the second temperature follows the function W2: w2> -130 ℃; this second time obeys the function T2: t2> 30 min. For example, the second temperature may be set to: 130 ℃, 135 ℃, 140 ℃ and 150 ℃; the second time may be set as: 30min, 35min, 40min, 50min, 60 min.
208. And cooling the mold to 25 ℃, simultaneously removing the pressurizing load, taking the cured and molded carbon fiber composite material out of the mold, and then carrying out appearance processing on the carbon fiber composite material.
Wherein the mold is cooled to 25 ℃, for example, the heating function in the closed container is turned off, the mold is naturally cooled to 25 ℃, or the mold is placed in a cooling plate, and the cooling of the mold is accelerated. And cooling the carbon fiber composite material in the mold to 25 ℃ along with the mold, removing the pressurizing load of the mold, opening the mold, and taking out the carbon fiber composite material in the mold. The carbon fiber composite material is also rough in shape or has defects, and the carbon fiber composite material needs to be processed into the required shape.
