4. COMPOSITES MATERIAL
What is a Composite?
• A composite material can be
defined as a combination of
a matrix and a
reinforcement.
• which when combined gives
properties superior to the
properties of the individual
components.
• The primary reason
composite materials are
chosen for components is
because of weight saving for
its relative stiffness and
strength
Why Use Composites?

5. COMPOSITION
Metal matrix composites
(MMC)
• MMC provides higher yield
strength and modulus than
the polymers.
• In our project we use two
metal matrix composites
are:
• Aluminium5383 alloy-
H116 grade.
• Lithium
Fiber Reinforcement
• Fibers are responsible for
high strength and stiffness
ratio to weight of the
composite.
• In our project we only one
fiber that is:
• Alkali Resistance Glass
Fiber (ARGF)
