Research progress in numerical simulation of fiber reinforced thermosetting resin matrix composites molding process

Abstract

Fiber-reinforced thermosetting resin composites are widely used in high-end manufacturing fields. The curing process involved resin flow, curing reaction, residual stress induced curing deformation and other steps. Numerical simulation of the forming process of fiber reinforced thermosetting resin composites was a complex problem of multi-field coupling. It was important theoretical and practical significance for the selection of process type, design of process parameters, and performance optimization of composite components to establish a perfect numerical simulation method to predict the curing behavior during the forming process. In this paper, the main research progress of numerical simulation of the forming process of fiber reinforced thermosetting resin composites is summarized. Moreover, the application conditions of different numerical models are discussed. The analysis of the application conditions of different models in the same field can guide the selection of the curing process and parameter design of composites. Improving the accuracy and reducing the cost are the main research directions of numerical model iterative optimization. On this basis, the numerical simulation of the molding process of fiber reinforced thermoset resin matrix composites, suggesting that future research could be carried out in the areas of multiscale modelling of resin flow in composites is summarized, the application of machine learning and material genome methods in the optimal design of components of composites and the effect of residual stresses on the properties and service life of composites.
