This document specifies requirements for 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 carbon fibre fraction over 60 % by volume; and

—    have a thickness within 3 mm.

This document specifies the methodologies to express the mechanical properties as characteristic values, appearance and dimensions, and sampling test.
