The properties of composite materials are closely related to the microstructure of the fibers or particles, matrix, and interfaces that can be studied, thanks to the use of a high resolution electron microscopy (HREM). It represents, in fact, one of the most powerful methods that can be used to clarify the microstructure of composite materials.
In this article, a brief description of the structure of HREM is reported first to describe some principles that are to the base of the image formation. Moreover, a discussion on the specimen preparation is reported, and finally, some applications to some composite materials are explained.
