Tensile Properties of CFRP and Hybrid FRP Composites at ...

The test results show that the tensile strength of carbon fibers in different FRP sheets decreases significantly with increasing temperature, and remains almost stable at an ultimate value (3000 MPa) after the polymer exceeds its glass transition temperature (T g), which is higher than the tensile strength of the non-impregnated fiber sheets at room temperature. At elevated temperatures, the hybridization of fibers can reduce the scatter of the tensile strengths of CFRP composites.
