摘　　要：根据复合材料固化成型原理,建立采用连续编织-缠绕-拉挤成型工艺生产的复合材料直管的传热模型以及固化动力学模型,利用有限元软件ANSYS和APDL语言开发复合材料直管固化过程数值模拟程序,以三维复合材料直管为模型进行固化数值模拟仿真,从而分析不同参数对采用连续编织-缠绕-拉挤成型工艺复合材料直管固化成型过程中的温度与固化度的影响。通过对复合材料直管模型进行固化数值模拟仿真分析可以得到工艺参数(如初始温度、加温历程、拉挤速度等参数)对固化过程的影响规律。对应用连续编织-缠绕-拉挤成型工艺生产的复合材料直管进行在线温度测试,测试结果表明数值模拟与实际生产工艺贴合,对实际生产有指导意义。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.
