Abstract

An increasing application of Carbon-fiber-reinforced-polymer (CFRP) in civil structures has been witnessed in recent years, however, the impact behavior of CFRP rod and CFRP strand failed to meet the expectation whilst was seldom reported. In present paper, the impact behavior of CFRP rod and strand was investigated by conducting Charpy impact tests on four groups of specimens, which composed of CFRP rod, entire CFRP strand, central and outer individual wire of CFRP strand. All specimens were cut into 100 mm long and impacted by a Charpy impact energy of 300 J. Test results showed that the damage modes include debonding between fibres and matrix of CFRP rod and wire decentralization and fracture of CFRP strand. The average absorbed energies for CFRP rod and CFRP strand are 45.3 J and 32.9 J, respectively; the average absorbed energies for central and outer individual wires of a CFRP strand are both 2.5 J.
