EXPERIMENTAL RESEARCH ON THE EFFECT OF COMPRESSIVE STRAIN RATE OF GLASS FIBER REINFORCED PLASTIC RODS

Abstract

Abstract: In order to study the compressive property of GFRP rod, quasi-static compressive test and impact performance test are carried out, by adopting WAW600 microcomputer controlled electro-hydraulic servo universal testing machine and Φ37 split Hopkinson pressure bar (SHPB). GFRP rods show typical brittle failure instead of yield characteristics and plastic deformation in quasi-static conditions. The effect of strain rate is sensitive at the low speed of 100N/s to 500N/s. The slopes of ascending stress-strain curves, the peak stresses and the peak strains increase with the strain rate under the impact loading. The compressive strength increases greatly, and the dynamic load coefficient is large than 1.35, up to 1.58.

Key words: composite, impact performance test, stress-strain curves, effect of strain rate, peak stress, peak strain, dynamic load coefficient
