Strength and Deformability of Polymer Composites Under Tensile and Compressive Loads

The paper presents the investigation results on mechanical-and-physical properties of po­lymeric composites used for reinforcement. The values of the main strength and deformation properties are experimentally obtained for glass fiber-reinforced (GFRP) and carbon fiber-reinforced polymers (CFRP) under static axial tensile and compressive loads. The alkaline medium resistance of GFRP and CFRP bars is estimated in this paper. The deformation diagram is constructed for GFRP and CFRP bars under the static loads. The estimated coefficients are suggested for the dynamic strengthening of reinforcement under the dynamic load.
