  • 摘要: 连续玻璃纤维增强聚丙烯(GFRPP)复合材料杆集成了热塑性树脂可多次成型、环境友好、可回收利用和玻璃纤维高应变、低成本等优点,在混凝土结构领域,GFRPP复合材料有望替代钢筋和热固性纤维增强聚合物(FRP)筋成为新型热塑性复合材料。本文采用加速实验研究了模拟海水-海砂混凝土环境下GFRPP杆的水吸收及层间剪切性能长期演化规律与退化机制。研究结果表明:GFRPP杆吸水行为符合Fick定律,21℃、40℃和60℃浸泡温度下GFRPP杆的饱和吸水率分别为0.63%、0.78%和0.81%;经120天21℃、40℃和60℃模拟海水-海砂混凝土孔溶液浸泡后,GFRPP杆层间剪切强度保留率分别为80.5%、72.8%和66.5%。最后,结合SEM和FTIR表征技术,揭示模拟海水-海砂混凝土孔溶液浸泡下GFRPP杆性能退化机制。
