Fibre-reinforced polymer (FRP) reinforcement of concrete — Test methods — Part 3: CFRP strips

This document specifies test methods applicable to unidirectional carbon fibre-reinforced polymer (CFRP) strips as external-bonded reinforcements on the concrete substrate.

This document is applicable for the CFRP strips that:

— consist of carbon fibre and thermoset resin;

— are manufactured by pultrusion method;

— have a higher carbon fibre fraction such as over 60 %; and

— have a thickness within 3 mm.

Also, the test pieces for determining tensile properties are cut down from CFRP strips along the CFRP strips axis, and have bonded anchorage block at the both ends.
