玄武岩纤维片材和碳纤维片材高温后拉伸性能比较
The Comparison of Tensile Strength after High Temperature of BFRP Sheets and CFRP Sheets
摘要
Abstract
The BFRP sheets and CFRP sheets with and without the impregnating by epoxy resin are taken as the objects to study their tensile performance after high temperature. The test results show that the tensile strength and modulus of BFRP sheets are far less than those of CFRP sheets both at room temperature and after high temperature, while the elongation of BFRP sheets is generally larger than that of CFRP sheets. The tensile strength of FRP sheets can be improved obviously due to the existence of the epoxy resin at room temperature, but the effect is not obvious after high temperature, especially for the CFRP sheets. The changing regularities of tensile strength of the BFRP sheets and CFRP sheets with the temperature are comparable; there is a trend of drop-ascend-drop for the tensile strength with the increase of temperature, and the tensile strength gets its maximum value at about 150℃. When the temperature is higher than 200℃, the longer the treatment time is, the more the tensile strength and modulus of the FRP sheets decrease.关键词
