基于多尺度联合仿真的短切CFRP注塑制件的力学性能分析
Mechanical Property Analysis of Short-cut CFRP Injection Molded Parts Based on Multi-scale Joint Simulation
摘要
Abstract
Short-cut carbon fiber reinforced composites(CFRP)are prone to uneven distribution of fibers due to flow and shear during the injection molding process,leading to performance differences in different parts of the parts,and traditional structural analysis methods often fail to take into account the influence of the manufacturing process on the mechanical properties of the structure.To address this problem,a multi-scale joint simulation model of short-cut CFRP injection tensile parts was established based on Moldflow,Digimat and ABAQUS,and the force distribution of the structure was analyzed.The effects of different fiber orientation tensor,fiber mass fraction,and fiber aspect ratio on the mechanical properties of CFRP injection molded parts were also investigated.The analysis results show that the tensile strength of the material tends to increase with the increase of fiber orientation tensor,fiber mass fraction and fiber aspect ratio,the modulus of elasticity tends to increase significantly with the increase of fiber mass fraction and fiber aspect ratio,the value of the tensile failure strain at rupture becomes significantly smaller with the increase of the fiber mass fraction and larger with the increase of the fiber length and diameter ratio.关键词
