1 Introduction
Wing is considered as the main part of the aircraft for generating lift and make it fly [1–
3]. Many kinds of loads act over and underneath the wing which can create structural
damage easily. The composite materials have many advantages in order to increase
the strength without loading much weight. In aerospace industries, composites are
always in demand for a lightweight, high thermal conductivity, high strength and
high stiffness applications. As the metal matrix composites in which metal is used
as a matrix for reinforcing, have low density, high compression and high tensile
strength and good processability, it is used in aerospace applications. MMC’s are
an economically great solution for the demand for lightweight material with good
structural properties when compared to other composite materials such as laminated
composite.
The reinforcement matrix interfaces are important to choose accurately because
the selected alloy may have a different set of physical, chemical properties [4, 5].
The reinforcement material is inserted into the matrix to enhance or reduce their
properties like wear resistance, hardness, density, porosity, mechanical strength etc.
The reinforcement may be done in a continuous manner or discontinuous. By the
stir casting process, MMC can be produced. In this process, mechanical stirring is
used to mix dispersed phase like short fibres or ceramic particles and molten matrix.
It is a cheap and best way in liquid state fabrication. The LM6 and fly ash matrix
material is considered a good combination for aircraft wing structure [6]. Aluminium
matrix composites can provide good strength in case of elevated temperatures also
and it also has high stiffness. Other properties like lower density, excellent abrasion
resistance, good thermal conductivity, etc. made the composite popular in automotive
and mechanical field.
Aircraft wing has to be analysed for suitable lift generation with its strength [7–9].
The design and analysis of aircraft wing allows comparing different results in various
aspects to get the desired result.
2 Material Selection
Material selection plays a very major and vital role in making of aircraft wing as
well as whole aircraft structure. Aluminium (LM6) and fly ash have been reinforced
together for obtaining a new material which can meet the need for better strength,
High thermal conductivity and low weight. As these parameters are essential for fabricating the aircraft, by keeping these parameters in mind material has been selected.
Aluminium (LM6) and fly ash have been taken in different constituents and has been
tested. It has been found that by increasing the fly ash weight percentage strength and
toughness of the material is also increased. 15% of Fly ash has been found suitable
for reinforcing with Aluminium.
