Carbon fiber laminates manufacturers in China. pre-pressed cfrp laminates very ideal for bridge strengthening.
1.2mm Carbon Fiber Strips , Carbon Fiber Sheet Laminates for Bridge Tunnel Reinforcement
Item# CarbonLami 312
Fiber Materials: 4900Mpa 12K
Thickness: 1.2mm
Carbon fiber reinforced unidirectional sheet, formed as putting the carbon fiber impregnated with resin, then hardened in mould and pultrusion. Adopted with high quality carbon fiber material with good basic resins, carbon fiber sheets feature good performance as high tensile strength, corrosion resistance, shock resistance, impact resistance.
Range of Application
Bending, and Shearing reinforcement for Concrete beams
Reinforcement for Concrete floors, bridge, concrete and brick walls.
Reinforcement for shear wall, bridge piers and piles
Reinforcement for chimneys, tunnels, pools and concrete pipe
Features
1, high tensile strength, corrosion resistance, shock resistance, good impact resistance;
2, light weight, good flexibility;
3, easy for handling and good quality assurance
4, good durability and corrosion resistance.

Processing Flow
Preparation → Concrete surface treatment → Mix and paint the base resin material → Leveling → Mix and paint the impregnated resin → Pasting the carbon fiber sheet → Surface protection.
Attention
1, on-site workers should take appropriate protection measures and take care of fire and keep good ventilation.
2, When open the roll, the sheet may occur to bounce up, pay kind attention.
3, The sheet is conductive, take care of the electrical appliances nearby.
