【摘要】 用正交试验设计的方法研究了玻纤/填料质量比、玻纤长度及混合时间等主要因素对BMC(预制整体模塑料)力学性能的影响。在系统地分析试验数据的基础上,以BMC的力学性能为参考值,得出了以上3个因素对BMC力学性能的影响趋势曲线;用扫描电镜讨论了3因素与BMC的微观结构及力学性能的关系,并获得了优化BMC的方案,所得的BMC的弯曲和冲击强度分别达到96.35 MPa和21.82 kJ/m2。更多还原

【Abstract】 Stirring time,the length of glass fiber and ratio of glass fiber/filler were considered and optimized by using Latin Square Design.The influence of three factors on mechanical properties of BMC was also discussed and the trend curves were given respectively.The relationships among three factors and microstructure and mechanical properties of BMC were discussed by SEM.Moreover,the BMC formulation was optimized to get excellent mechanical properties of BMC.BMC produced by this formulation has the best flexural strength(96.35 MPa) and impact strength(21.82 kJ/m~2).更多还原
