Composite material compression molding heating compensation method

The invention discloses a composite material compression molding heating compensation method, and relates to the technical field of composite material hot press molding, and the method comprises the following steps: S1, arranging temperature measuring equipment in areas, corresponding to different thicknesses of a composite material molded part, of a compression molding tool; s2, corresponding auxiliary heating devices are additionally arranged at the positions, corresponding to the composite material molded part, of the compression molding tool, wherein the thickness of the composite material molded part is large; and S3, the auxiliary heating devices are started at the initial temperature rising stage of the compression molding tool, and the temperature difference of different thickness areas of the composite material molded part is reduced. The temperature difference of the composite material molded part in the compression molding forming process is reduced, temperature compensation is achieved for a low-t
