What are composite materials (definition) ?
 Composite material is a material composed of two or
more distinct phases(matrix phase and dispersed phase)
which are chemically & physically different
 Composites are used because overall properties of
the composites are superior to those of the individual
components

The primary phase, having a continuous character , is
called matrix. Matrix is usually more ductile and less hard
phase. It holds the dispersed phase and shares a load with
it.
The second phase (or phases) which is embedded in the
matrix is called dispersed phase. Dispersed phase
is usually stronger than the matrix, therefore it is called
reinforcing phase

The following are some of the reasons why composites
are selected for aerospace applications:
• High strength to weight ratio (low density high tensile strength)
• High creep resistance
• High tensile strength at elevated temperatures
• High toughness

The Boeing 777 is a long-range wide-body
twin-engine jet airliner manufactured
by Boeing commercial airplanes. It is the
world's largest twinjet and has a capacity of
over 300 passengers, with a range of 5,235
to 9,380 nautical miles (9,695 to 17,370
km) .12% composites are used

12. The Boeing 787 Dreamliner is a long-range, mid-size wide-body, twin- engine jet airliner
developed by Boeing commercial airplanes. Each 787 contains
Approximately 32,000 kg of carbon fiber reinforced plastic (CFRP),
made with 23 tons of carbon fiber. Carbon fiber composites have a higher
strength-to-weight ratio
than traditional aircraft materials, and help make the 787 a lighter aircraft.
Composites are used on fuselage, wings, tail, doors, and interior.

15.  composite materials will play an increasingly
significant role in aerospace application
 B787,A350-XWB used more than 50% composite
materials
 With their unique combination of properties such
as low weight, high strength, low flammability,
smoke density and heat release, non-toxicity and
durability, composites are ideal for many
aerospace applications, both for interior and
exterior components.
