What are composites?
• Composite materials are composed of two or more constituents stuck together with an epoxy
• These constituents have different physical and chemical properties that allow them to remain separate in the final structure
• The constituents are layered on top of each other as shown above

Why do we use composites?
• Composites are used in the aerospace industry because they provide benefits that their substitute materials cannot.
• The plane that uses composites the most in aerospace is the Boeing 787 Dreamliner.

Benefit to aerospace companies
• The largest benefit of composite materials in aircraft structure is the light weight of the material.
• Boeing 787 consumes 20% less fuel than the similar sized 767

• Another benefit is the machining required to manufacture composite materials.
• The machines are smaller and much cheaper than machines used to manufacture metal materials.

Disadvantages of composites
• The manufacturing process of composite materials has not been perfected.
• The process of perfecting it is time inefficient because companies must perfect it with trial and error.

Composites expanding to other industries
• The new Lenovo laptop is structured with carbon composite materials

• Composites are now being used in the new z06 Chevy Corvette
• Composites make up the body and the hood.
