  1. Composite Materials in the aerospace industry

  2. 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

  3. 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.

  4. Boeing 787

  5. Airbus’ use of composites

  6. 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

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

  8. 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.

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

  10. Composites expanding to other industries • Composites are now being used in the new z06 Chevy Corvette • Composites make up the body and the hood.
