INFLUENCE OF PROCESS FACTOR FOR CURING TEMPERATURE FIELD ON FIBER-REINFORCED RESIN MATRIX COMPOSITES

Abstract

Abstract: This paper mainly focuses on curing temperature field of composite materials with auxiliary material layer and forced convection. Using finite element method, the solutions of temperature-chemical coupling field and fluid-solid heat transfer field are obtained. Especially, the effects of the thickness, density of breath cloth, thickness and wind pressure of laminar air flow on curing temperature, curing degree and curing rate are analyzed numerically.The results show that the density and thickness of auxiliary material layer have little effect on curing field. The laminar thickness and the wind pressure will cause the curing temperature lag and overstep and the curing rate of the resin can be modulated by wind pressure or wind speed in autoclave.

Key words: air laminar flow, finite element, temperature field, curing degree
