Abstract
This paper is a short introduction to the common type of damages in composite structures and different ways of their inspection. Due to the high increase of interest in composite materials in past decades and their usage in different structures, there is a need to discuss the damage types in them along with different ways of inspection. This paper provides a short review of these facts in order to fill out the gap that there is in the literature. Major emphasis is placed on the damage types and their mechanisms and inspection methods, mostly focused on wave propagation based structural health monitoring (SHM).

Summary
Composite materials are increasingly used in many industries including aerospace, automotive, electrical industries, etc. The increasing interest in composites is due to their significant advantages over metals, such as light weight, corrosion resistance, design flexibility, high strength, better fatigue life, etc. Composites have been used widely by different industries and in aerospace industries in past decades. A. Ghobadi increasing usage rate of composites in past four decades in aerospace industry [4], including the infrastructural installations which can affect the behavior of the electrical system by inducing harmonics as they role in insulations [5] or by affecting the internal electrical grid when used in the generators [6]. The common damage types in composites and different methods to inspect them are discussed shortly. The last section provides the information about different methods for damage detection
