What is carbon fiber mesh (carbon fiber geogrid, carbon net fabric)?
Carbon fiber mesh is a new type of pavement and roadbed reinforced geotechnical base material made of carbon fiber filaments coated with inorganic sizing agent. These carbon fiber products have the advantages of high tensile strength in the warp and weft directions, low elongation, good temperature range, aging resistance, and good alkali resistance.
Carbon fiber meshes are widely used in the reinforcement of asphalt pavements, concrete pavements and roadbeds. Compared with traditional materials, it extends the service life of roads and prevents flexing and cracking. Carbon fiber geogrid can also be used to reinforce soft soil foundations such as railways, airports, irrigation canals, and dams.
Shenghe carbon fiber mesh reinforcement system refers to the method of using carbon fiber mesh cloth and matching spray polymer mortar to strengthen the structure.
Shenghe carbon fiber mesh, it adopts imported carbon fiber yarn and special weaving process. The woven carbon fiber mesh cloth is impregnated in corrosion-resistant resin, and then dried through.
Shenghe multi-layer coating process to form a mesh-like whole. It has light weight, high strength, two-way force bearing, convenient construction, and can be used for harsh environmental construction and other advantages.
Shenghe wet spray polymer mortar: composed of special cement and various other additives. It has the characteristics of fast setting, anti-disturbance, high bonding strength, no shrinkage, and high crack resistance, and the active ingredients in the mortar are compatible with the carbon fiber grid coating.
Shenghe carbon fiber mesh fabric is used together with Shenghe wet spray polymer mortar to ensure sufficient holding and anchoring force between the carbon fiber mesh and the mortar, and has good fire resistance, good peeling resistance, strong durability and reinforcement The effect is obviously excellent.
carbon fiber mesh is woven from 12K, 24K carbon fiber. Carbon fiber models include T300, T700, T800, M30, M35, M40, T1000, high strength, high strength medium mold, high strength high mold ,The carbon fiber filaments we use include many well-known domestic brands and well-known imported brands, such as:
Toray and Teijin, Mitsubishi Chemical, Hexcel and Zoltek, Hyosung, Aksaca, Cytec solvay group, Sgl.
Characteristics of carbon mesh fabric
Low elongation, good temperature range, aging resistance, and good alkali resistance, light weight, high strength, two-way force bearing, convenient construction.
Abrasion-resistant, chemical-resistant, heat-insulation, flexible and easy to operate, smooth surface and uniform force distribution, corrosion resistance, wear resistance and impact resistance.
Good fire resistance: the carbon fiber grid matched with polymer mortar has good fire resistance. The 1cm thick mortar protective layer can meet the fire protection standard's 60-minute fire protection requirements, greatly reducing the impact of fire and other major safety hazards on the structure.
Applicable to humid environments: there is no requirement for the humidity of the base layer before construction, and the reinforcement operation on the humid interface is extremely smooth. Ideal for reinforcement in wet environments such as tunnels.
Breathability and wear resistance: carbon fiber composites are non-toxic, have stable chemical properties and X-ray permeability, so they are widely used today. Our carbon fiber mesh fabric has good wear resistance and impact resistance, much better than many ordinary materials. Weaved from carbon filament, it has high strength, low density and thin thickness. It basically does not increase the self-weight and cross-sectional size of the reinforcement components. It is widely used in the reinforcement and repair of various structural types and structural shapes such as buildings, bridges, tunnels, etc., as well as seismic reinforcement and node reinforcement. Structural reinforcement.
Good durability and corrosion resistance: carbon fiber is an inert material, and the polymer mortar can provide alkaline protection to the original structure and has excellent performance in terms of durability and corrosion resistance. No cracks, high bonding strength, thin reinforcement thickness: excellent crack resistance; the active ingredients in the mortar ensure the bonding strength between the carbon fiber grid and the concrete; generally the mortar thickness can be controlled within 25mm, which basically does not increase the structure dimensions and weight.
UV resistance and corrosion resistance: carbon fiber composite materials can protect against UV rays and avoid the trouble caused by UV damage. It also has strong corrosion resistance and can work normally in very complex/harsh environments.
Applications of carbon fiber mesh fabric
Carbon fiber mesh fabric is widely used in tunnel reinforcement, bridge reinforcement, industrial and civil construction reinforcement, water conservancy reinforcement (soft foundation reinforcement of dams), municipal reinforcement (soft foundation reinforcement of roads) and other fields. It can be used for the reinforcement of soft soil foundations such as railways, airports, irrigation canals, etc. The application range of carbon fiber mesh is also gradually expand. Carbon fiber mesh is a non-magnetic material and is very suitable for use in structures with high environmental magnetic requirements such as hospitals, laboratories, and observation stations. In coastal areas, carbon fiber mesh can also be used instead of steel bars to solve the problem of steel bar corrosion.
Carbon fiber mesh is widely used in bending reinforcement, shear reinforcement, seismic reinforcement, crack control reinforcement, axial compression reinforcement, and is used for bending and shear reinforcement of concrete structures. It is also widely used for earthquake protection of various industrial and civil building structures. Anti-cracking and anti-corrosion reinforcement, reinforcement of tunnels, harbor facilities, chimneys, warehouses, and factories.
Carbon fiber mesh fabric can also be used for: acid and alkali resistance, axial compression reinforcement, crack control reinforcement, etc. It has good crack resistance and reinforcement. Carbon fiber is an inert material with corrosion resistance and good durability. The polymer mortar can be used to repair the original structure. steel bars to protect high bonding strength, suitable for seismic reinforcement of various buildings, stable performance in self-adhesion and mutual adhesion of steel plates and concrete, acid and alkali resistance, fast construction speed in large areas, strong bonding force, aging resistance, resistant to media acid, alkali, water, good performance.
