采用Deform软件对生物质复合材料连续固态挤出自增强过程进行计算机模拟,通过对速度分布云图以及最大等效应力场的分析,研究了挤出口模锥角对连续固态挤出自增强过程的影响;同时,通过实验对挤出过程中制品的表面形态与模拟结果进行对比,验证了模拟结果的可靠性,最终发现选取口模锥角20°~30°可以获得理想的生物质复合材料制品。 Deform software was used to simulate the continuous solid state extrusion self-reinforced process of biomass composites. By analyzing the velocity distribution and the maximum equivalent stress field, the influence of extrusion die taper angle on the continuous solid state extrusion self- At the same time, the surface morphology and simulation results of the extrusion process were compared by experiments to verify the reliability of the simulation results. Finally, it was found that the ideal biomass composite material can be obtained by selecting the taper angle of die from 20 ° to 30 °.
