TENSILE PROPERTIES OF FRP COMPOSITES AT ELEVATED AND HIGH TEMPERATURES

Abstract

A series of tensile tests were conducted to investigate the tensile mechanical properties of carbon fiber, glass fiber and basalt fiber reinforced polymer sheets at temperatures ranging from 16•Ž to 200•Ž. Additionally, corresponding no-impregnated fiber sheets were tested at 16•Ž as a reference. The results show that the tensile strength of different fiber reinforced polymer (FRP) sheets is reduced significantly with an increase in temperature. However, the tensile strength of FRP sheets still remains a stable residual value after the polymer reaches its glass transition temperature (Tg), and this value is higher than the tensile strength of non-impregnated fiber sheets.
