A Study on Friction Stir Welding of Composite Materials for Aerospace Applications

Abstract

Composite materials define the new age for the development of technologies. In a recent study of aerospace structure, conventional materials are replaced by almost 75% by modern composites. The strength-to-weight ratio of aluminum alloys makes it an attractive choice among other materials for industries. Carbon fiber-reinforced composite materials are better alternatives to conventional materials to prepare lighter panels. In many applications, the joining of these composites becomes troublesome. The promising technique to join the advanced composites is still unrevealed. The proper joining method is an essential need for composites. With this aim, we carry out the study to check the feasibilities of Friction Stir Welding for light panels used in aerospace industries. Friction Stir Welding is a solid-state welding method. The external tool solidifies and mixes the metal at the edge line. We reviewed several research articles to understand the difficulties associated with the friction stir welding method.
