【Abstract】 This paper makes research on the curing of the composite pipe which is produced based on braidingwinding-pultrusion process. According the principle of composite curing,this paper sets heat transfer model and cure kinetic model,which is based on composite braiding-winding-pultrusion process. The ANSYS and APDL language are used to develop the curing process numerical simulation procedure. Through the simulation of three-dimensional resin thin-walled pipe and the experimental verification,the process parameters affecting the curing temperature and curing of the process of forming the new pipe were analyzed. The influence law of initial temperature of pipes,heating process and pultrusion speed on solidification process of the new process for pipes is attained by the simulation analysis for the fitting. The on-line temperature testing is operated on the new process pipes,and the result shows that the simulation is identical with the actual production process,which can guide the actual production.更多还原
