.Aircraft structures designed with aluminum-based composite materials have given improved results. These materials have helped in developing airframes which are much lesser in weight and at the same time have shown improved strengths. Lighter aircraft has its own advantages and making a one of this type provides corresponding advantages in terms of maintenance and fuel efficiency. It has its environmental benefits. To achieve the best efficiency level in the new design models the material needed for the development of the same should be both strongest and lightest among all substitutes currently available to the technology sector. The research being conducted has the purpose of developing lighter aircraft through composite materials with the employment of cheap and high-quality manufacturing technologies. Structures can also be developed through the use of conventional aluminum alloys and cheaper to produce but the composite materials despite being costlier both in terms of cost of raw material and development techniques are better and are the future of the aircraft engineering (Day).
Advance aircraft materials are supposed to bring further reduction in the overall weight of the complete structure and improving the strength with the ultimate aim being the increase of the service life of various components of the structure against continuous fatigue and cyclic usage. Materials like fiberglass have got wide spread usage in different components of the aircraft (Quilter). This most common composite material in the current scenario was used for the first time in Boeing aircraft in the 1950s. It was developed through the embedding process of glass fibers in the resin matrix. But with the beginning of the 1960s, the use of composite materials came under widespread usage with one material acting as a matrix while the others are being .embedded in that matrix and serves as reinforcements and holds everything together and intact and with the overall effect being greater strength with reduced weight (Quilter). The current researches processes are delving into the development of composite materials with common matrix material underuse are epoxy, bismaleimide, or polyimide and glass fiber, boron fiber, carbon fiber, and others as reinforcing materials (Day). .
