Abstract

Delamination problems are one of the most important issues affecting the applications of composite laminates. Delamination reduces overall structural performance of composite laminates such as stiffness, strength, and buckling load. The advantages of the fiber optic sensor are the potential solutions for sensing of smart structures. Therefore, it is necessary to observe the signal characteristics of fiber optic sensor(FOS) and to identify the influence of delamination failure on composite laminates. The delaminated unidirectional composite specimens subjected to the compressive load were tested to study the characteristics of FOS signals when the buckling and the growth of delamination occurred.
