Materials and Design Criteria for Airbus A380: Aerospace Engineering

Aerospace Engineering

Introduction
• One of the key consideration in aircraft design is the
safety issues.
• The materials used play a key role in enhancing the
safety of the body design.
• The Airbus A380 body was able ti utilize most of the
materials such as Aluminum alloys and carbon fibre
reinforced plastic composite (Mendell, 2013).
• Airbus A380 utilized about 61% aluminum alloys
and 21% composite materials.

Design criteria
• Aluminum alloys are able to offer the damage
tolerance when they are used for design of
different parts.
• These alloys are one of the best structural design
material choices for the airbus A380
(Langewiesche, Drummond, & Hoopla digital,
2009).
• They provide the required structural integrity to
resist external loads and bear internal loads of the
auircraft.

Design criteria
• Aluminum alloys offer the important aspect of
weight reduction
• They also maintain the structural strength
which is needed to avoid key accidents.
• In the examination of the fatigue, high
frequency eddy current equipment are
employed to aid the detection of the non
visual cracks on the aircraft.

Design criteria
• also. Another material used for aircraft design
is the is the carbon fibre reinforced composite.
• Airbus A380 was able to employ the use of
carbon fibre reinforced plastic composite
(Alexander, 2009).
• Weight reduction in some key parts which did
not bear the weight of the airplane was
enhanced by the use of the carbon fibre
reinforced plastic composite.

Design criteria
• Design technologies are important in imp-0roving
materials characteristics.
• These technologies were able to offer the required
technological and structural advancement of the
carbon fibre reinforced plastic composite.
• Additionally, the choice of the carbon fibre
reinforced plastic composite was an important
development which did not interfere with the
structural strength design of the Airbus A380
(Avrenli, & Dempsey, 2014)
