Product overview
Performance and application overview.
The carbon fiber board was molded with 12K carbon fiber and epoxy resin via pultrusion, carbon fiber board strength. Its elongation rate (above 1.6%) and many other indicators far exceed the requirements of the national standard, and meet the requirements of high-strength grade I carbon fiber board. The straightness is high (below 1‰ of camber), which is conducive to load transmission and has a good strengthening effect.
Applications
◆ Flexural strengthening of concrete beams and slabs.
◆ Seismic retrofitting of buildings.
◆ Reinforcement of masonry walls.
◆ Crack control in bridge decks and parking structures.
◆ Timber structure reinforcement
Product Features
◆High strength grade I: All performance indexes meet the requirement of high strength grade I carbon fiber board.
◆High straightness: After forming, it is straight and smooth, the curvature is less than one thousandth, and the strength of carbon fiber is fully exerted.
◆Various specifications: More than 20 kinds of carbon plate specifications, which can meet different reinforcement needs
◆Wide carbon plate: The substrate has low leveling requirements, high strength, and can be as wide as the beam, with good reinforcement effect and fast construction efficiency.
◆Random inspection:The product has Passed safety appraisal, environment-friendly and non-toxic testing and other stringent tests, and random inspections and type inspections can be conducted.
