Tegris MEEN 3344 Stephen Bump
Tegris • Is a relatively new material produced by Milliken and Company • The company’s 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
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
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
Applications • Used in NASCAR’s new car’s 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
