4. MATERIALS IN THE AUTOMOTIVE
INDUSTRY
โข Making cars, parts and components, along
with future trends, are steel, aluminum,
magnesium, copper, plastics and carbon fiber.
5. Introduction
โข 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. โข 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.
