| 摘 要： | 以甲基丙烯酸甲酯(polymethyl methacrylate,PMMA)和丙烯酸甲酯(polymethyl acrylate,PMA)为原料、短切碳纤维(Cf)为增强相,采用悬浮聚合法制备碳纤维增强聚甲基丙烯酸甲酯-聚丙烯酸甲酯基复合材料(carbon fiber-reinforced polymethyl methacrylate-polymethyl acrylate matrix composites,Cf/PMMA-PMA)。研究碳纤维含量(质量分数,下同)对Cf/PMMA-PMA显微结构及力学性能(抗折强度、抗压强度和拉伸强度)的影响。结果表明:随碳纤维含量增加,Cf/PMMA-PMA的挠度呈线性增长,而抗折强度、抗压强度和拉伸强度呈先增大后减小趋势。当碳纤维含量为15%时,Cf/PMMA-PMA的抗折强度、抗压强度和拉伸强度分别达到最大值115.5、244.6MPa和158.6MPa。

| Abstract: | Carbon fiber-reinforced polymethyl methacrylate-polymethyl acrylate matrix composites(Cf/PMMA-PMA) were prepared by a suspension polymerization process using polymethyl methacrylate(PMMA) and polymethyl acrylate(PMA) as raw materials and short-cut carbon fiber as reinforced phase.The influences of carbon fiber content(in mass,the same below) on microstructure and mechanical properties,such as flexural strength,compressive strength and tensile strength of the Cf/PMMA-PMA,were investigated. The results show t... |
