07 Assessment
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 ratio
- Tg >100 ?C reported for CFRP plate systems (adhesive-dependent)
Constraints
- Panel performance is highly design- and system-dependent (plate layout, adhesive, concrete)
- Fire performance requires system-specific testing and protection
- Specialist installation and QA/QC are required for bonded CFRP systems
