4.8oz KEVLAR 49® Tape Yard
Kevlar® is a high strength (5 times that of steel), high modulus (75% of carbon fiber) aramid fiber. Aramid is technically an aromatic polyamide, which is a complex hydrocarbon and a distant cousin of nylon. Kevlar® is the most impact resistant fiber on the market, also exhibits the highest tensile strength and highest resistance to damage, vibration and crack propagation. However, Kevlar® has very low compressive strength, so it is recommended that laminates carrying bending or compression loads have carbon fiber incorporated into the laminate to provide adequate stiffness. Kevlar® is also hygroscopic, ultra violet sensitive and un-sandable, thus it is not recommended as a sheathing or outer ply of the laminate. Kevlar® is categorized by weight per sq. yd., available in a cloth weave and sold by the running yard. The Kevlar tapes have a sewn edge for ease of use.
