Composite Materials in the aerospace industry Slide2
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 aboveSlide3
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.Slide4

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 767Slide7
Another benefit is the machining required to manufacture composite materials.
T
he machines are smaller and much cheaper than machines used to manufacture metal materials.
Benefit to aerospace companiesSlide8
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. Slide9
Composites expanding to other industries
The new Lenovo laptop is structured with
carbon composite materialsSlide10
Composites are now being used in the new z06 Chevy Corvette
Composites make up the body and the
hood.
