CFRP Laminates
Carbon FRP “Laminates” are used to structurally strengthen existing concrete, wood, or masonry members in flexure and shear. The CFRP Laminate is a pre-cured plate with a surface texture on one face, which helps improve bond with the structural adhesives. Structures that are deficient due to either a structural flaw, deterioration or because of a change in use can often be brought to a useful capacity using CFRP Laminate. Externally bonded FRP strengthening is analogous to steel plate bonding. Successful implementation of CFRP plate bonding is dependent on proper surface preparation, leveling and bond of the structural adhesive to the concrete and CFRP plate interfaces. Externally bonded CFRP Laminates work best in overhead applications for flexural strengthening where sufficient bond and development lengths can be achieved.
Externally Bonded Structural Strengthening
1. Flexural Strengthening of
2. Bridge Decks
3. Parking Garages
4. Floor slabs
5. Shear Strengthening
6. Change of Use Situations – Higher Loads
7. Return Deteriorated Members to Capacity
8. Additional Structural Capacity Without
9. Additional Dead Weight
Masonry Strengthening
1. In Plane and Out of Plane Strengthening of Masonry Shear Walls
2. “Event” Loading of Masonry – Blast, & Seismic
3. Restore Capacities of Cracked Masonry
Benefits of Carbon FRP “Laminate”
1. Furnished with guaranteed properties based on measured results. Manufactured in a controlled environment and not subject to vagaries of field wet lay-up systems.
2. Furnished with one face prepared for bonding to adhesive.
3. Much lighter weight than steel plate bonding
3. Will not rust or corrode
3. Can be used with multiple commercially available high strength adhesives.
GFRP & CFRP Wrapping
Glass fiber reinforced polymer and carbon fiber reinforced polymer are high strength polymers that are bonded to structures for strengthening purpose. It is able to conform to various geometric shapes and sizes.
Benefits of Wrap:
1. Ease of handling
2. High strength
3. Significant gain in load bearing capacity
4. Minimal change in structures weight, shape or appearance.
5. Minimum structure downtime
6. Economical to use
7. Effective for both wet and dry layup applications
8. Minimal clearance needed to install
Application Areas:
Column wrapping
1. Seismic strengthening
2. Confinement
3. Flexural strengthening
4. Increased ductility
5. Increased axial load carrying capacity
6. Shear strengthening
Beam / Slab strengthening
1. Shear
2. Flexure
3. Ductility
4. Reduces deflection
5. Limits cracking
Beam / Slab strengthening
1. In-plane shear/flexural retrofit
2. Out-of-plane shear/flexural retrofit
3. Concrete shear walls
4. Unreinforced masonry walls
5. Compressive load increases
Tank strengthening
1. Confinement/Bursting stresses
2. Minimizes crack propagation
3. Seismic stabilization
Substrates
1. Concrete
2. Steel

4. Timber
JACKETING:
Jacketing is the most popularly used method for strengthening of building columns. The most common types of jackets are steel jacket, reinforced concrete jacket, fibre reinforced polymer composite jacket, jacket with high tension materials like carbon fibre, glass fibre etc. The main purposes of jacketing are:
1. To increase concrete confinement by transverse fibre reinforcement, especially for circular cross-sectional columns.
2. To increase shear strength by transverse fibre reinforcement.
3. To increase flexural strength by longitudinal fibre reinforcement provided.
