摘要: 通过改变玄武岩纤维布、浸润树脂等因素,对玄武岩纤维增强复合材料进行湿热老化试验,系统研究随着老化时间的增长,玄武岩纤维增强复合材料抗拉强度、延伸率和拉伸弹性模量的变化规律,并与其他类型的纤维增强复合材料湿热老化性能进行比较。对玄武岩纤维在结构加固和修复中的应用和耐久性问题有一定指导意义。

Abstract: A series of basaltic fiber wet-thermal exposure tests were conducted.The type of basaltic fiber sheet and saturated resin were varied.As the time of aging test increasing,the tensile strength,elongation and elastic modulus of BFRP were studied.Further more,the same characteristics of GFRP and CFRP were consulted.It can be of some guiding significance to the engineering application of BFRP.
