By combining the high strength of carbon fiber reinforced polymer （CFRP） with the sensing characteristics of optical bragg grating （OFBG）, a smart CFRP-OFBG composite laminate is developed. Its mechanical properties and sensing characteristics are studied by test. The steel beams strengthened with prestressed CFRP-OFBG plates were tested to monitor the process of yield damage and strain while studying the flexural performance at the same time. The experimental results show that the prestressed CFRP-OFBG plate is a new material combined force and contingency perception; it can solve the problem of technology of embedded optical fiber Bragg grating and effectively improve the flexural capacity in the meanwhile, has good popularized value and application prospects.
