Carbon fiber board is made of carbon fiber impregnated with resin and then cured and continuously pultruded in the mold. High-quality carbon fiber raw material with good epoxy resin is used. The yarn tension is uniform, which maintains the strength of carbon fiber and the stability of the product. The tensile strength is up to 2400Mpa, and the modulus of elasticity is up to 160Gpa. Carbon fiber sheet has excellent seismic resistance, convenient construction, high efficiency of strength utilization, easy-to-guarantee construction quality, and convenient process.
Carbon board adhesive is a two-component bisphenol A modified epoxy resin, a non-hydrophilic product, with superb adhesion, excellent comprehensive mechanical properties, waterproof, anti-corrosion, and non-pollution. Can be constructed in a wide range of temperatures, with no precipitation, easy construction, and good process performance. Acid and alkali resistance, good aging resistance, low tide temperature sensitivity.
The basic principle of prestressed carbon fiber plate reinforcement is to make it in a higher stress level before the carbon fiber plate carries the load stress transmitted by the structure and play a certain strength in advance, to realize the effective use of its high-strength performance, the prestressed carbon fiber plate reinforcement system consists of three parts: anchorage, carbon fiber plate, and structural adhesive. The anchorage realizes the tensioning and fixing of the carbon fiber board, and the structural adhesive makes the carbon fiber board and the reinforced member form a whole with common stress.
In the process of reinforcement, relevant construction specifications are strictly followed to ensure that the bond strength between the carbon fiber board and the floor slab meets the design requirements. Through the prestressing technology, the bearing capacity and crack resistance of the floor slab are effectively improved. After the completion of the construction, after testing, the reinforcement effect is remarkable, reaching the expected design standards.
