Advancement in the application of alloys and composites in the manufacture of aircraft component: A review

Abstract

Abstract Failures in aerospace structural components have catastrophic consequences, which results in loss of lives and of the aircraft. Failure occurs when a component or structure is no longer able to withstand the stresses imposed on it during operation. Application requirements of aerospace components involves high durability in order to withstand high temperature and pressure environments (such as leaving the earth’s atmosphere or exposure to burning rocket fuel) and must be light weight for easy lifting and fuel efficiency for rockets. Compressor blades in aero-engines are designed for many distinct functions and are required to withstand high temperatures imposed on them by high rotational speed in the form of large centrifugal load and aerodynamic force applied as a function of pressure rise through each stage of the compressor. The paper reviews the advancement in the application of alloys and composites in the manufacture of aircraft component.
