• Definition of composite

• History of composite material
• Types of composite material
• Advantage and disadvantage of
composite material

3. A composite material: is a combination of two
materials with different physical and chemical
properties.
• When they are combined they create a
material which is specialized to do a certain
job, for instance to become stronger, lighter
or resistant to electricity.

4. History of composite material
• The ancient society glued wood strips on top of
each other at different angles to create plywood.
• Following this, in around 2181 B.C the
Egyptians started to make death masks out of
linen or papyrus soaked in plaster.
• Later on, both of these societies started to
reinforce their materials with straw to
strengthen mud bricks, pottery and boats.

5. • The 1930s was an incredibly important
time for the advancement of
composites.
• Glass fiber was introduced by Owens
Corning who also started the first fiber
reinforced polymer (FRP) industry.
• The resins engineered during this era
are still used to this day and, in 1936,
unsaturated polyester resins were
patented.

6. Types of composite material
• Ceramic matrix composite
• Metal matrix composite:
• Reinforce concrete
• Glass fiber reinforced concrete
• Plastic coated paper
• Engineered bamboo
• Sandwich panel

7. ceramic matrix composites (CMCs)
• Are a subgroup of composite materials
and a subgroup of ceramics.
• They consist of ceramic fibers embedded
in a ceramic matrix.
• The fibers and the matrix both can
consist of any ceramic material, whereby
carbon and carbon fibers can also be
regarded as a ceramic material.

8. Application
• Heat shield systems for space vehicles.
• Components for high-temperature gas
turbines such as combustion chambers,
stator vanes
• Components for burners, flame holders,
and hot gas ducts
• Brake disks and brake system
components

9. Metal matrix composite:
• is a composite material with fibers or
particles dispersed in a metallic matrix,
such as copper, aluminum, or steel.
• The secondary phase is typically a
ceramic (such as alumina or silicon
carbide) or another metal (such as steel).

10. Application
• High performance tungsten carbide
cutting tools
• Some tank armors may be made from
metal matrix composites.
• Some automotive disc brakes use
MMCs.
• Specialized Bicycles has used aluminum
MMC compounds for its top of the
range bicycle frames for several years.

11. Reinforce concrete
• Is also called reinforced cement concrete
(RCC) and ferroconcrete,
• Is a composite material in which
concrete's relatively low tensile strength
and ductility are compensated for by the
inclusion of reinforcement having higher
tensile strength or ductility.

12. Glass fiber reinforced concrete
• is a type of fiber-reinforced concrete.
The product is also known as glass
fiber reinforced concrete or GRC in
British English.
• Glass fiber concretes are mainly used
in exterior building façade panels and
as architectural precast concrete.
• Somewhat similar materials are fiber
cement siding and cement boards.

13. Plastic coated paper
• Plastic-coated paper is a coated or
laminated composite material made of
paper or paperboard with a plastic
layer or treatment on a surface. This
type of coated paper is most used in the
food and drink packaging industry.

14. Engineered bamboo
• a set of composite products produced
from bamboo.
• It is designed to be a replacement for
wood or engineered wood, but is used
only when high load bearing strength is
not required because building standards
for this type of use have not been
agreed by regulatory bodies.

15. Sandwich panel
• A sandwich panel is any structure made
of three layers: a low-density core (PIR,
mineral wool, XPS), and a thin skin-
layer bonded to each side.
• Sandwich panels are used in
applications where a combination of
high structural rigidity and low weight is
required.

16. Advantage of composite material
• Low cost compared to metal
• Design flexibility
• Low weight
• Durability
• Electrical insulation
• High impact strength
• Composite material did not rust or
corrode readily

17. Disadvantage of composite material
• Composites are more brittle and
easily damage
• Repair problem
• Not elastic
