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. 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.

5. Airbus’ use of composites Aircrafts built using composites% made from Composites Airbus A32010% Airbus A38025% Airbus A400 M30-35% Airbus A35053%

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

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

8. Disadvantages of composites The manufacturing process of composite materials has not been perfected. 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.
