300gsm Unidirectional Carbon Fiber CFRP Sheets For Beam Strengthening
High strength, unidirectional Carbon Fiber CFRP Sheets
pre-saturated to form a carbon fiber reinforced polymer (CFRP
sheets) fabric used to strengthen structural concrete elements. its
good choice for building beam and columns strengthening.
To complete the reinforcing CFRP sheet system, carbon fibre
wrapping of the structural beam will be undertaken. Woven
unidirectional carbon fibre CFRP sheets will be wrapped around the
beam in a series of over-lapping layers to further strengthen the
reinforced concrete.
A mix of usually carbon fibre fabrics, and an epoxy resin, wrapping
systems are custom designed for each project and application. Where there is an element of corrosion in the structure, carbon
fibre wrapping can be used to both weather-proof corrosion and
structurally re-enforce the structure. The impervious material will
protect a structure from moisture intrusion and further corrosion,
reducing the need for ongoing maintenance work.
Advantages of Carbon Fiber CFRP Sheets
• Easy installation
• Corrosion resistance
• Short construction period
• No maintenance required
• Light weight, no influence to original structure
• Low cost, cost effective compared with other methods
