Description
High impact and toughness composites are often constructed using a combination of KEVLAR fabrics laminated under high platen press, vacuum assisted resin transfer or resin fusion or dry and wet lay-up vacuum which offers exceptional tensile strength and high mechanical performance.
In general KEVLAR 49 fiber possess the following properties:
- High tensile strength
- Five times stronger per weight unit than steel
- High modulus of elasticity;
- Very low elongation up to breaking point
- One of the lowest density composite materials
- Chemical inertness and resistance
- Very low coefficient of thermal expansion
- High fracture and impact resistance
- High cut resistance
- Ease of use and processibility
- Flame resistance
Kevlar is the DuPont registered trademark for the generic Aramid type fibers. It is one of the lowest density materials that demonstrates high strength, high modulus organic fiber. Its weight to strength ratio surpasses that of carbon fiber and fiberglass. It combines high tensile strength (43,000 PSI) and high modulus (19 million PSI) with light weight and toughness superior to other reinforcing fibers for plastics. At cryogenic temperatures (-320°F.) performance is excellent with essentially no embrittlement or degradation of fiber properties. Kevlar 49 can offer both a significant weight saving and improved stiffness versus glass in addition to superior vibration damping and good impact resistance.
