Aramid Fibers By: Me
What are Aramid Fibers? • Molecular structure made of linked Benzene rings and amide bonds • Para-type • Meta-type TECHNORA : co-poly-(paraphenylene/3,4'-oxydiphenylene terephthalamide) TWARON : poly-(paraphenylene terephthalamide) (PPTA) TEIJINCONEX : poly-(metaphenylene isophthalamide) (MPIA)
Para-Type • Known for superior tensile strength and elasticity • Tensile strength 2.5 times of (strength type) nylon fibers. • High impact resistance • Fatigue resistance • High tensile modulus • Chemical resistance • Heat resistance
Products • Made from Para-type Chopped fiber(Short cut fiber) Filament yarn Staple fiber Spunnized yarn
Applications • Rope, Cable, and Cord • Rubber materials • Construction • Reinforcement of plastics • Safety Materials .
Meta-Type (My Favorite) • Very Heat Resistance • Do not ignite • Won’t melt
Cool Products • Pioneer speakers • long stands of Aramid fibers into the mix, along with the polypropylene and carbon and Rigilite • makes the cone more dense, much stronger, and even more durable • More powerful bass. Rich, full-bodied sound character with excellent midrange depth. • The open, natural sound found in paper cones (but without the fragility of paper). • Durability. The cones stand up to high power levels and the tough conditions within a car, such as temperature extremes and humidity, that will thrash weaker speakers.
