Numerical simulation study on the pultrusion curing process of carbon fiber/epoxy resin composite materials
摘要
Abstract
In the pultrusion process of composite materials,the internal temperature and the curing rate of the resin show a set of strong coupling relationships.According to the theory of unsteady heat conduction and curing dy-namics during the curing process of composite materials,a two-dimensional model was established,and systemati-cally carried out different working condition of pultrusion research on the influence of the curing process.The numer-ical simulation results showed that under the same conditions,increasing the volume fraction of resin,increasing the wall temperature and increasing the pultrusion speed can promote the curing process.Compared with the benchmark case,when the volume fraction of resin increases to 0.5,wall temperature to 220℃,pultrusion speed up to 0.9 m/min,the curing time was reduced by about 25%,67%and 47%respectively.The effective thermal conductivity and curing reaction kinetic parameters of the composite have great influence on the temperature field and curing de-gree field,which dominate the pultrusion curing process of the composite.The research results in this paper provide a theoretical basis for optimizing pultrusion process and determining reasonable process parameters.关键词
