摘要

The present paper investigates mechanical properties of composite polymer rebar. The values of basic strength and strain properties of composite rebar when exposed to static axial tensile and compressive load were determined experimentally. The strain and stress values in composite rods were measured using high-precision sensors. The stress-strain diagram of glass- and carbon-liber composite rebar under static compression and tension were presented, including general data of its stress and strain limits and typical failure schemes. Based on the literature review analysis authors proposed the coefficients of dynamic hardening of composite rebar under short-term dynamic loading.
