Experimental Research of the Smart Composite Reinforcement

Wenfeng Bian, Guowei Zhang, Miao Miao


In order to make the composite reinforcements equipped with sensors, the optical fiber-composite smart reinforcements and resistance strain gage-composite smart reinforcements were designed and made. Based on experiments and finite element analysis, the resistance strain gage-composite reinforcements pasted on composite beams played a good role in reinforcement and normal stress monitoring. The result shows that, after double-sided reinforcing, bearing capacity of composite beams increased, while stress values of reinforcement sections decreased by about 50%, providing a reference to the smart composites used for structural reinforcement and health monitoring.
