摘要
本文主要研究了柔性管道的结构中起增强作用的增强层材料在长期载荷下的蠕变行为。文中用连续拉挤成型工艺制备了CGFRPP单层板,利用万能力学试验机和DMA测试仪测得了预测模型和理论所需要的力学数据,根据所测得的力学数据分别用Burgers模型和时间-温度-应力等效原理(TTSSP)预测CGFRPP的长期力学性能,并将两种预测方法所得的结果进行了分析和比较。研究表明TTSSP对CGFRPP复合材料低应力下的蠕变行为预测具有较好的适用性,Burgers粘弹性模型对于CGFRPP复合材料的蠕变行为预测具有良好的适用性。
This paper mainly studies the creep behavior of reinforcing layer materials in the flexible pipe structure under long-term load.The CGFRPP single-layer board is prepared by continuous pultrusion process in paper.The mechanical data needed for the prediction model and theory are measured by the capacity test machine and DMA tester.The Burgers model and time-temperature are used according to the measured mechanical data.The principle of stress equivalence(TTSSP)predicts the long-term mechanical properties of CGFRPP,and the results obtained by the two prediction methods are analyzed and compared.The results show that TTSSP has good applicability to the creep behavior prediction of CGFRPP composites under low stress.The Burgers viscoelastic model has good applicability to the prediction of creep behavior of CGFRPP composites.
