Tegris

• Is a relatively new material produced by Milliken
  and Company
• The companys goal was to make a material that
  has similar characteristics to carbon fiber with
  out the expensive price tag associated with
  carbon fiber.
• Tegris has approximately 70 of the strength of
  Carbon fiber with only 10 the cost.
• 100 polypropylene Thermoplastic composite

3
How its made

• Is made from polypropylene tape yarn with a
  highly-drawn core for strength properties within
  a lower melt polymer matrix for composite
  processing
• The tape yarn is woven into fabric or sheets.
• Then it is pressed together with a mixture of
  both heat and pressure using a process called
  thermoforming
• Can be molded to make just about any shape

4
Advantages

• Contains to glass, major safety issue due to
  fragments if it were to break
• 100 recyclable
• Great impact resistance
• Keeps its strength even at temperatures all the
  way down to -40 degrees C
• Great Stiffness compared to other materials

5
Applications

• Used in NASCARs new cars front air dam called
  the splitter.
• building materials
• Watercraft (boats, kayaks ect.
• Safety equipment such as helmets
• Even outdoor furniture and playground equipment
• Starting to be used in ballistics
