玄武岩纤维复合材料蠕变性能研究

Research on Creep Behavior of Continuous Basalt Fiber Reinforced Plastics

摘要: 树脂基基复合材料具有粘弹性,长期在外力作用下会发生蠕变现象,导致复合材料的刚度和强度都发生衰退,致使复合材料结构失去继续承载的能力。本文对连续玄武岩纤维(Continuous Basalt Fiber简称CBF)增强树脂基复合材料在不同应力水平下的长期力学行为进行研究,初步探讨了CBF复合材料的蠕变性能。

Abstract: As the viscoelastic nature of fiber reinforced plastics,creep may occurre under long term external force,then the stiffness and strength decrease gradually,and the whole structural system will fail at last.The creep curves of continuous basalt fiber reinforced plastics are presented subjected to various stress levels,and creep behavior of continuous basalt fiber reinforced plastics is studied in this paper.
