Analysis of influencing factors of warpage deformation of epoxy/carbon fiber composite-molded products
This article addressed the issue of warping deformation in epoxy resin/carbon fiber sheet-molded composite flat panel products.,the flatness of the panel products was measured to characterize the extent of warping deformation by us-ing a three-coordinate measurement device.The results indicated that the warping deformation varied from 0.302 to 1.29 mm.Through an orthogonal experimental variance analysis,the significance of various molding process parameters on warping deformation was determined with molding pressure having the most significant impact,followed by demold-ing speed,holding pressure time,and molding temperature.Furthermore,a Duncan's multiple comparison method was used to assess the differences in the significance levels among these factors,the trends in the influence of each process pa-rameter on warping deformation in the products was further analyzed.The mechanism of influence factors for the warping of the products was analyzed,and these factors include fiber distribution,pore characteristics,upper and lower mold tem-peratures,and cavity pressure distribution.
