Method & Evidence

AimTo investigate the influence of varying strain rates and temperatures on the tensile properties and failure mechanisms of GFRP composites and glass fibers.
MethodExperimental Testing
ProcedureGFRP composite samples were subjected to tensile testing across a range of strain rates (25-200 s⁻¹) and temperatures (-25 to 100 °C) using a servo-hydraulic system. Complementary tests on glass yarn were conducted at different strain rates (40-160 s⁻¹) and temperatures (25-100 °C) using a drop-weight impact system. Quasi-static properties were also measured for reference. Weibull statistics were applied to analyze tensile strength variability.
