在采用熔丝制造方法3D打印短纤维增强热塑性复合材料时,需要对打印过程进行数值模拟,以预测打印路径之间的空隙,并对复合材料的熔丝进行估计。考虑复合材料颗粒熔化和凝固的潜热,将运动颗粒半隐式方法推广到短纤维增强热塑性复合材料的液体模拟中。对短碳纤维/PA6复合材料的3D打印过程进行了数值模拟,并与实验结果进行了比较;模拟的打印路径截面结构与实验结果吻合较好。
In 3D printing of short fiber-reinforced thermoplastic composites using the fused filament fabrication method, numerical simulation of the printing process is required to predict voids between print paths and to estimate the fusion of composites. In this study, the moving particle semi-implicit method for liquid simulation was extended to short fiber-reinforced thermoplastic composites considering the latent heat of melting and solidification with composite particles. Numerical simulation of the 3D printing process of short carbon fiber/PA6 composites was conducted, and the results were compared with those of experiments; the simulated print path cross-sectional configuration agreed well with the experimental results.
