Composite materials are made by combining two or more materials to give unique properties. The document discusses the definition of composites, examples like fiberglass, the history from ancient Egyptians to modern plastics, the five basic types, properties depending on materials used, applications in aircraft and boats, advantages like strength and light weight, and disadvantages like cost fluctuations and lack of recyclability. It provides references for further information on composite materials.

4. Definition:
A composite material is made by combining
two or more materials into each other. The
two materials work together to give the
composite unique properties.
`

5. Examples for composite:

6. History of composite material:
1-The first uses of composites date back to the
1500s B.C. when early Egyptians used a mixture of
mud and straw to create strong buildings.

7. 2- In 1200 AD, the Mongols invented the first
composite bow. Using a combination of wood,
bone, and “animal glue”.

8. 3-In the early 1900s, plastics such as vinyl,
polystyrene, phenolic and polyester were
developed. In 1935, Owens Corning introduced
the first glass fiber, fiberglass

9. Types of composite material:
There are five basic types for composite materials:
Fiber, particle, flake, laminar or layered and filled
.composites

10. Their properties:
Properties of composite depend to the materials which
are combining together.
For example:
:Fiberglass
 Strength
 felixibilty

11. Their application
We used composite materials in many things
For example :
 AIRCRAFT/MILITARY

12. • MARINE
Products for commercial, pleasure and naval boats and ships

13. Advantage and Disadvanage
Advantage
 High Mechanical Properties
 Flexibility of Design Option
 Ease of Fabrication
 Light Weight
 Corrosion Resistant
 Impact Resistant

14. Corrosion Resistant

15. Disadvantages
 Not often environmentally friendly
 Low recyclability
 Cost can fluctuate
 Can be damaged
 Low reusability

16. Damaged
