4. MATERIALS IN THE AUTOMOTIVE
INDUSTRY
• Making cars, parts and components, along
with future trends, are steel, aluminum,
magnesium, copper, plastics and carbon fiber.
5. Introduction
• In total, about 39 different types of basic
plastics and polymers are used to make an
automobile. More than 70% of the plastic
used in automobiles comes from four
polymers.
6. Basics On 7 Common Types of Plastic
1) Polyethylene Terephthalate (PET or PETE)
2) High-Density Polyethylene (HDPE)
3) Polyvinyl Chloride (PVC or Vinyl)
4) Low-Density Polyethylene (LDPE)
5) Polypropylene (PP)
6) Polystyrene (PS or Styrofoam)
7) Other.
8. • The most commonly used commercial
aerospace structural materials are aluminum
alloys, titanium alloys, high-strength steels,
and composites, generally accounting for
more than 90% of the weight of airframes.
