A REVIEW ON PROPERTIES OF AEROSPACE MATERIALS THROUGH ADDITIVE MANUFACTURING

Abstract

Additive Manufacturing (AM) process has been effective in producing materials that are being utilized by the aerospace industry in order to improve their performance by increasing their properties. Industry now opts for this technique over conventional methods as it has enormous advantages and applications. This Additive Manufacturing process is capable of producing complex near net shape of parts. The materials that are produced by this technique for aerospace industries are metal alloys, metal matrix composites, polymer matrix composites, ceramic matrix composites and nano-composites. Many of the composite materials are still under research and development. In this study, a literature review on the mechanical properties of the materials that are used in the aerospace industry by AM process is discussed and these properties are also compared with the materials produced by conventional methods. The purpose of this review is to highlight the importance of Additive Manufacturing technique and also understand the effect of this process on the materials tested. During this work, the evolution of materials in the aerospace sector, the basic concept of AM technique, the application of the materials, the properties obtained when processing is done, the limitations and the scope for research are given.
