Frp Rebar Wrap Properties: AFRP_wrap
Fiber-reinforced polymer (FRP) reinforcement properties for concrete structures — GFRP/CFRP/BFRP/AFRP bars per ACI 440.1R-15, and CFRP/GFRP/AFRP externally bonded wraps and pultruded plates per ACI 440.2R-17; includes tensile strength, elastic modulus, ultimate strain, density, CTE, bond strength, and environmental reduction factors CE
