21/30402991 DC

This standard 21/30402991 DC BS ISO 18319-2. Fibre reinforced polymer (FRP) reinforcement for concrete structures is classified in these ICS categories:

• 83.120 Reinforced plastics
• 91.080.40 Concrete structures
• 91.100.30 Concrete and concrete products

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.

The methodologies to express the mechanical properties as characteristic values, appearance and dimensions, and sampling test are specified in this document. These requirements are to be met by the manufacturer of the product. The properties for design are calculated from the characteristic values, as prescribed in an appropriate design code which is in accordance with ISO 14484.
