环氧树脂/碳纤维复合材料模压制品冲击强度影响因素分析
Analysis of influence factors on impact strength of epoxy/carbon-fiber-composite-molded products
摘要
Abstract
The influence of molding temperature,molding pressure,holding time,and closing speed on the impact perfor-mance of epoxy resin/carbon-fiber-laminate-molded products was investigated through an orthogonal experiment.The of products exhibited significant anisotropy in their impact strength.A range analysis method was used to demonstrate the influence of each factor on the impact performance by an increasing order as follows:holding time>closing speed>mold-ing temperature>molding pressure.The optimal combination of process parameters was determined to be a molding tem-perature of 130℃,a molding pressure of 500 kN,a holding time of 540 s,and a closing speed of 1 mm/s.Compared to the maximum value obtained in the orthogonal experiment,the validation experiment based on this parameter combina-tion for the new products showed an increase in the impact strength by 9.75%.The microstructure of typical impact frac-ture samples was analyzed to explore the microscopic mechanism of the influencing factors on the impact performance of the products.关键词
