A control method of intelligent sub-regional temperature control composite material laying mold

Abstract

The invention discloses an intelligent sub-area temperature-controlled composite material laying mold and a control method. The control areas are separated by a heat insulation layer to reduce the heat transfer rate between each temperature control area; the circulating fluid is used to increase or decrease the surface temperature of the mold; the circulating pipeline is used to load the circulating fluid and set In the mold body; a temperature control adjustment component, which is used for splitting or merging of the circulating fluid after the temperature is raised or lowered to input different temperature control areas to adjust the surface temperature of the mold body in different temperature control areas; a temperature sensor, It is used to detect the mold surface temperature. The invention can meet the temperature process curve of the thermoplastic composite material member in the stage of laying and in-situ solidification and molding, and can guarantee the quality and performance of the final product.

Description

technical field [0001] The invention belongs to the field of composite material laying moulds, and in particular relates to a control method for an intelligent sub-area temperature-controlled composite material laying mold. 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 ...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the problems existing in the background technology, the present invention provides an intelligent sub-area temperature-controlled composite material laying mold and a control method to solve the problem of wrinkles, air bubbles, layers, Problems such as voids, failure to fit, internal thermal stress and thermal deformation, and the inability to accurately control the cooling rate during the solidification molding stage lead to low crystallinity of the resin and cannot guarantee the quality and performance of the final product.
