scope:

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.
