Abstract

The invention discloses a compensation mold-repairing method for the profile deformation of a composite material component mold, and belongs to the technical field of curing and forming for compositematerial components. The compensation mold-repairing method for the profile deformation of the composite material component mold is characterized by comprising the following steps: a, obtaining a moldrepairing surface based on a profile compensation algorithm for joint deformation; b, determining the shape and compensation amount of a compensation mold-repairing area, deviating from an original mold profile, and accumulating forwards a compensation deformation area; c, adopting a glass fiber reinforced plastic material for filling the shape of the forwards-accumulated mold repairing area andcompensating a gap value, and then carrying out laying and curing grinding to obtain an initial profile mold of the target forming mold; and d, obtaining the initial mold profile of the forming mold through digital measurement, comparing the initial mold profile with a target mold profile, obtaining the shape, the position and the size of a difference area, and carrying out fine adjustment and grinding on the difference area by using a grinding tool to finish mold profile qualification correction. According to the invention, the forming mold can greatly reduce the shape deviation between an actual part and a theoretical part, shorten the correction period and reduce the cost.

Description

technical field [0001] The invention relates to the technical field of solidification and forming of composite material components, in particular to a method for compensating and repairing the mold surface deformation of a composite material component mold. Background technique [0002] For non-flat panel composite parts, the solidification deformation of the composite components will have an extremely adverse effect on the shape accuracy of the parts and the connection and matching of the components. In order to obtain ideal composite components, the following two methods are currently mainly used To reduce or eliminate curing deformation: one is to adjust and optimize the curing process parameters, adjust the layering method and curing process; the other way is to modify the mold surface. [0003] In practical applications, more methods are used to modify the mold surface. Traditional composite component mold correction is basically done by experiment and trial and error....
