I. Overview: CFRP selection of high quality raw materials imported from Japan Toray carbon fiber processing, product performance and full compliance with national standards. (GB50367-2006 "reinforced concrete structure design specifications", GB / T 21490-2008 "structural reinforcement and restoration with carbon fiber sheets"). Second, the details: CFRP CFRP selection of high quality raw materials imported from Japan Toray carbon fiber processing, product performance and full compliance with national standards (GB50367-2006 "reinforced concrete structure design specifications", GB / T 21490-2008 "structural reinforcement repair carbon fiber sheet "). First, the advantages of a carbon fiber cloth, light weight, easy construction. The basic components without increasing weight, does not change the size of the member section. 2, high tensile strength, high elasticity, can be obtained with the use of the same steel plate reinforcing effect. 3, anti-acid corrosion, high durability, can be used in any harsh environment. Used in conjunction with a structural adhesive, to prevent infiltration of harmful media, the internal structure of the protective effect; 4, a small thickness, easy overlap. Bendable winding, for all types of surfaces, shaped reinforcement member is more significant advantage. 5, softness, and can freely cut for beams, columns, plates, pipes and other shapes and wall components, tightly bonded and reinforced concrete surface, easy to guarantee construction quality. Without large-scale construction equipment, can be extended to any overlap bond, no fire operations. 6, supporting superior permeability epoxy glue, construction convenient and shorter duration. 7, environmental pollution, residential construction is still available. 8, storage for a long time, long operational period. Second, the CFRP Scope: CFRP carbon fiber impregnated plastic supporting the use of carbon fiber composites become applicable to concrete flexural, axial compression, large eccentric compression and tension members reinforced reinforcement, wooden structure, which can effectively improve bearing capacity of components, seismic performance and durability. Engineering problems dealing with the following outstanding options: 1, building use load increase; 2, works using functional changes; 3, material aging; 4, concrete strength grade is lower than the design value; 5, structural cracks handling; 6, bad Environmental service component repair, protective. Fields sporting goods, industrial products: 7, for other purposes. Third, the construction process 1, construction preparation prepare construction plans and construction plans, carbon fiber sheets used to deal with, and the supporting resin, prepare equipment and other pre-construction preparations. 1, the base surface treating the substrate surface should be fully polished, without any attachments, paste parts have sharp edges and corners need to be polished into a rounded, the minimum inner diameter of 20 mm. Since the purpose of the use of carbon fiber sheet is to improve the structural members, should determine the status of the base surface, in order to ensure its ability to transfer loads from the fabric to the surface of the structure. 2, epoxy primed and correct irregularities at the ink lines. 3, impregnated with epoxy resin coated surface bonding glue to glue the full amount must be sufficient. 4, will cut a good carbon fiber cloth affixed to the concrete surface coating, CFRP to be straight, extended. (CFRP if joints, lap length should be 20cm, and the joints should be 1/3 of the total length of the base material, not in the middle of the substrate) 5, the use of hard rubber or plastic scraper stick repeatedly prompted rolling carbon fiber cloth straight, extended, no bubbles, adhesive full penetration. 6, again in the face of a roll of cloth material impregnated with epoxy resin glue to ensure adequate coverage of the surface of the cloth, to ensure adequate infiltration CFRP fibers. 7. Finally 3--6mm sand (quartz sand) sprinkled on the surface to be coated with rubber to ensure adhesion of the paint layer. Fourth, a construction conditions, construction surfaces should be clean and dry. 2, the construction temperature theoretically should be more than 5 ℃, less than 40 ℃. 3, open-air construction is prohibited in the rain. 4, the relative humidity is greater than 85%, or concrete surface where condensation allowed construction. 5. Please set up a local exhaust system workplaces. Job protection should be a mirror, protective gloves, dust masks and other protective tools. Please rinse with water after use soap if attached to the skin. Try not allow fluff and debris attached to the outlet line and other electrical products, power should not make contact with this product. V. Note 1: The carbon fiber cloth should be stored in a cool, dry place, keep the cloth clean, avoid outdoor sun and rain; 2: CFRP prohibited from dust, twisting and bending phenomenon, which would significantly reduce the strength; 3: CFRP is a conductive material, the construction should pay attention to electrical safety. Six, CFRP technical parameters Model intensity level Weight (g / m2) theoretical thickness (mm) Tensile strength (MPa) elastic modulus (GPa) Elongation (%) CDHJ-Ⅰ-200 high-strength grade Ⅰ 200 0.111 ≥3400 ≥240 ≥1.7 CDHJ -Ⅰ-300 high-strength grade Ⅰ 300 0.167 ≥3400 ≥240 ≥1.7 CTHJ -Ⅱ-200 high-strength grade Ⅱ 200 0.111 ≥3000 ≥210 ≥1.5 CTHJ -Ⅱ-300 high-strength grade Ⅱ 300 0.167 ≥3000 ≥210 ≥1.5
