Application of Acoustic Emission to Detect Damage in Composites Materials

Abstract

In today’s modern world, the use of composite in the construction of various equipment and parts due to many advantages such as; weight reduction, design durability, flexibility, etc., is increasing. Damages may occur unintentionally in composite materials, either during the manufacturing process or during the normal lifetime of the part. Structural health monitoring (SHM) of composite structures is an industry requirement. The acoustic emission method can be used as an effective nondestructive testing (NDT) method to continuously monitor the development of damages in composites. In this chapter of the book, it has been prepared with the aim of application of AE to detect damage in composites. For this purpose, the literature done in the field of SHM of composite structures using the AE method is reviewed. The content of this chapter shows the importance of using the AE method for SHM of composite structures.
