3D打印连续碳纤维复合材料冷却模型及变形研究
Cooling model and deformation study of 3D printing continuous carbon fiber composites
摘要
Abstract
To investigate the dynamic cooling behavior and warping deformation behavior of 3D printed continu-ous carbon fiber reinforced plastic(C-CFRP).Firstly,a cooling model considering material properties and printing parameters for 3D printed C-CFRP composite wires was established in this paper.And thermocouples and thermal imagers were used to monitor the temperature changes of composite wires over time under different process parame-ters.The results were verified with the calculated values of the cooling model,with a minimum error of 11%.Then,the influence of different printed parameters and dimensions on warping were explored for 3D printed C-CFRP thin pieces,and the dynamic temperature changes and warping degree during the forming process were tested using ther-mocouples and coordinate measuring instruments.The results shown that the time when the extruded wire exceeds the glass transition temperature was positively correlated with the printing temperature and layer thickness,and neg-atively correlated with the printing speed;the warpage of C-CFRP thin films was positively correlated with layer thickness and length,but negatively correlated with printing temperature and printing speed.A reference for the de-velopment of 3D printed high-precision C-CFRP technology was provided in this article.关键词
