Tensile Strain of Composite Laminates Using Embedded Fiber Bragg Grating Sensors
摘要
Abstract
Fiber Bragg grating (FBG) sensors embedded in composite laminates were used to monitor the strain during tension process of the composite laminates and the strain derived from the FBG was compared with the strain gage. It was verified that the effectivity and reliability of the FBG sensors in the process of monitoring composite strain. FBG sensors were embedded in different plys of the laminates, and the tension properties of the composites were studied. The results show a good agreement with the strain gages. The FBG sensors could measure the strain of composites laminates effectively. While the embedded FBG has a little effect on the tensile strength of the composite laminates.关键词
