A loading comparison experimental study including CFRP, (JFRP and CFRP-GFRP hybrid strengthened concrete prisms is carried out to analyze their working mechanism and failure feature. Test results show that the CFRP-GFRP hybrid composite could carry forward the advantages and overcome shortages of the materials,leading to a significant increase of the strengthening efficiency.
Keywords: hybrid fiber; carbon fiber; glass fiber; hybrid effect; concrete prism
