• In comparison of glass cloth, carbon fabric carries absolutely high strength, high elasticity, and high thermo-stable characteristics in the current composite market. It also broadly used in industrial field by using its functional property.

Specific use: Carbon fabric also can be produced prepreg type and even if it is definitely stronger than steel, it is lighter than general F.R.P. currently, it is widely applied in the aerospace business field and also it is used for industrial, constructional and sports leisure business field.

● Applications

● Applications and Properties

• Steel reinforced concrete structures constitute the majority of building and civil structures and they may degrade in durability following natural or artificial impact. In the past, reinforcing was mainly carried out for durability after deterioration due to natural conditions. However, reinforcing is required for various purposes, including the enhancing of? bridge loads due to increases in traffic, remodeling of structures, and reinforcing structures against earthquakes. We offer a CFRP strip in addition to its carbon fiber sheet toaid such new reinforcing?requirements.

● -CPS Reinforcement Applications

• One-way carbon fiber reinforced panels, made by dipping in epoxy resin and curing, are materials for reinforcing or repairing concrete structures as follows:

• Increased Load Requirements • ＊Increased Live Load • ＊Increased Traffic • ＊Heavy Machinery Installed in Buildings • Damaged Parts in Structures • ＊Aging • ＊Corrosion on steel plates • ＊Damages by earthquake • ＊Durability degraded parts after a fire • Durabillity Enhancement • ＊Reduced stress of rebar • ＊Prevention of further cracking, suppressing crack width from expanding • ＊Reduce deformation

• Change of Design Parameters • ＊Satisfy aseismatic design requirements • ＊Satisfy design change requirements • Defects in Design or Construction • ＊Structures with insufficient rebars • ＊Structures with insufficient thickness elements

Advantages

• ＊ High strength: Being made of high strength carbon fiber, this product features outstanding tensile strength

• ＊ Light weight: Nearly no weight increase after reinforcing with this product. • ＊ The bending performance of the concrete structures is improved. • ＊ The base composite material has outstanding fatigue features. • ＊ Repair work period is short. • ＊ Corrosion resistant: May be applied to diverse conditions for outstanding resistance

against corrosion. • ＊ Reliability: Actively used in advanced countries. • ＊ Unlimited length without any additional joint work. • ＊ Simple to apply: May be applied at difficult to access sites and light and simple to

around

● -CPS Product Features

• ＊CPS is a product that is produced by dipping high-strength and high tensile carbon fiber (80% in weight) in epoxy resin. Carbon fiber sheets need to be dipped in epoxy resin at the site. However, -CPS is fast to apply and users may omit the on-site dipping process. Since it is already dipped in epoxy resin, defects from poor dipping or curing are prevented. It features a uniform quality because of a consistent resin coat.

• ＊ CPS features outstanding tensile strength for bending load, deformation or increased stress. No multiple layers are required like with a carbon fiber sheet. It features smaller workarea and is ideal for reinforcing flat concrete structures like slabs and beams thanks to its outstanding tensile properties.

• ＊ Because of the tensile properties are higher than that of a carbon fiber sheet, it does not require application all over the concrete element. Thus, it is easy to monitor crack development or water leaks after application.

• ＊ As -CPS is already cured, it may be easily stored and used almost permanently without deformation or deterioration.

• ＊ -CPA adhesive used for -CPS is highly viscous, easy to apply without downflowing.

● Chopped CF• Compatible with cement for constructing bridge and road.

Type Used Yarn Chopping Length

Thermosetting TOHOYARN

3mm, 6mm8mm, 12mmThermoplastic

● Chopped Strand

•• E - Glass chopped strands for BMC are widely used in transportation, construction,

electronics, chemical industry.E - Glass Chopped Strands for Thermoplastics are mainly used in injection and compressionmolding processes.

● Waste carbon Fiber

•• For making carbon chopped or recycle to make carbon material.

● Carbon Fiber Vinyl• Carbon fiber modification on engine hood,empennage, surrounding surface, car handle,

rotary plate, ect,. is the desire of car fans. Car fans are bothered by this problem any more after the carbon fiber vinyl come out as its price is lower and easy to operate.
