A method of effecting high temperature vacuum heating and cooling suitable for conducting heat treatment to be performed on components used in a display apparatus. The heating / cooling method includes the steps of: heating a plate-like member placed in a reduced pressure atmosphere in a chamber by heating means opposed to the plate-like member; and cooling the plate-like member by a cooling plate which is opposed to the plate-like member, with the heating means therebetween, the cooling plate having a heat reflecting function. The cooling plate has an emissivity of not less than 0.50 but not more than 0.80 so as to minimize a sum of a requisite time for the heating step and a requisite time for the cooling step.

The invention discloses a rapid compression molding process for carbon fiber prepreg. The carbon fiber prepreg is used as a forming material, a prepreg molding process is used as a foundation, an online molding and curing process, a next-period thermal laying process and a previous-period product cooling aftertreatment process can be carried out simultaneously, and finally, buckling deformation of the product does not exist. In the whole process, steps of preforming, coating of a release agent and mold cleaning are not required, the mold heating and cooling time in every forming period is saved, therefore, the forming time is greatly saved, the production efficiency is improved, power consumption costs for heating and cooling are reduced, and a forming environment is improved; and the shortest final forming period can be controlled within 5 minutes, the quality of formed products is good, and requirements of automobile parts and requirements of the production trend can be met.
