摘要

通过正交实验研究模压工艺参数对环氧树脂/碳纤维(EP/CF)片状模塑料SMC模压成型制品力学性能的影响,分析了各工艺参数对制品拉伸强度和弯曲强度的影响趋势.通过方差分析,得到工艺参数对于拉伸强度的影响大小为合模速度>模压温度>模压压力>保压时间,工艺参数对于弯曲强度的影响大小为合模速度>模压压力>模压温度>保压时间,同时得到了对拉伸强度和弯曲强度的显著性因素;研究了拉伸破坏模式及失效机理,采用K-均值方法并选取典型试样观察,发现环氧树脂与基体的结合程度是影响拉伸强度的原因.

Abstract

The influence of molding process parameters on the mechanical properties of carbon fiber/epoxy sheet-molded products was studied through orthogonal experiments,and the influence trend of various process parameters on their ten-sile strength and flexural strength was analyzed.The influence of process parameters on the tensile strength was obtained by variance analysis in an increasing order of:clamping speed>molding temperature>molding pressure>holding time,and the influence of process parameters on bending strength was obtained in an increasing order of:clamping speed>molding pressure>molding temperature>holding time.Moreover,the significance factors affecting the ten-sile strength and flexural strength were also obtained.The tensile failure mode and failure mechanism were studied,and the typical samples were selected for observation using the K-mean method.The results indicated that the bonding de-gree between the matrix and epoxy resin affected the tensile strength of the molding products.
