Study on CFRP Sheet Strengthening Technique to Reinforced Beam

Abstract

The application of carbon fiber reinforced polymer (CFRP) / resin composite materials to strengthen the reinforced beam is introduced. The CFRP material has many advantages such as high strength, good fire resistance and conductivity. It can not only be used as a structural material for reinforcing the strength of structures, but also can be applied to the safety diagnosis and life prediction of large structure as an intelligent material. The objective is to investigate the natural frequency reinforcing performance of CFRP sheets by combining the finite element simulation analysis and experimental research. The results show that CFRP sheets can reinforce the strength of structure and enhance its natural frequency, which provides a fundamental study for the application of CFRP materials in civil engineering.
