Description
Carbon-fibre reinforced concrete panels use CFRP plates or fabrics bonded to concrete to increase tensile and flexural capacity. Manufacturer data for prefabricated CFRP plates report tensile strength around 2900?3100 N/mm?, tensile modulus about 165?170 GPa, elongation at break ~1.8%, density ~1.60 g/cm?, and glass transition temperature >100 ?C (EN 61006).

Advantages
CFRP plates provide high tensile strength (~2900?3100 MPa) and high modulus (165?170 GPa)Low density (~1.60 g/cm3) provides high strength-to-weight ratioTg >100 ?C reported for CFRP plate systems (adhesive-dependent)
Cautions
Panel performance is highly design- and system-dependent (plate layout, adhesive, concrete)Fire performance requires system-specific testing and protectionSpecialist installation and QA/QC are required for bonded CFRP systems
