Intelligent regional temperature control composite material laying mold and control method

Abstract

The invention discloses an intelligent regional temperature control composite material laying mold and a control method. The mold comprises a mold body, wherein a composite material is laid on the surface layer of the mold body, the surface layer of the mold body comprises a plurality of temperature control areas, and the plurality of temperature control areas are separated by thermal insulation layers to reduce the heat transfer rate among all the temperature control areas; circulating liquid, which is used for increasing or decreasing the surface temperature of the mold; circulating pipelines, which are used for loading the circulating liquid and arranged in the mold body; temperature control adjusting assemblies, which are used for increasing or decreasing the temperature of the circulating liquid and then inputting the circulating liquid into the different temperature control areas in a diverging or converging mode to adjust the temperature of the surface layer of the mold body inthe different temperature control areas; and temperature sensors, which are used for detecting the surface temperature of the mold. According to the mold, the requirement of a temperature process curve of a thermoplastic composite material component at a laying stage and an in-situ curing molding stage can be met, and the quality and performance of a final product can be ensured.

Description

technical field [0001] The invention belongs to the field of composite material laying moulds, in particular to an intelligent sub-area temperature-controlled composite material laying mold and a control method. Background technique [0002] Due to the advantages of high specific strength, large specific modulus, fatigue resistance, and corrosion resistance, composite materials are suitable for the manufacture of large-scale and complex components, which improves the quality of finished products and energy utilization, and is widely used in aerospace, marine and automotive industries. and other fields. According to the shape of fiber-reinforced composite materials, composite lay-up technology can be mainly divided into two types: tape laying and wire laying. The components formed by laying composite materials need to be laid on a mold with the shape of the target component. The composite material is laid layer by layer on the surface of the mold to finally form the target c...
