Roving technical fabric Vectran®

polymerfor thermal protectionfor the aeronautical industry

Vectran® is the property of the Japanese company Kuraray and is processed by IMATTEC. This polymer is based on LCP (Liquid Crystal Polymer) technology. IMATTEC, as a specialist in advanced technical textiles, has chosen to promote Vectran® for its many qualities and high levels of performance. For almost 20 years, IMATTEC has developed a unique know-how in the use, transformation and spinning of the Vectran® fibre. All of this is possible thanks to the development of dedicated production lines adaptable to almost all the demands of this unique fibre named LCP Vectran®. The main characteristic of the Vectran® fibre is its very high mechanical strength. About 30% more efficient than aramid, it also has excellent resistance to fatigue (torsion, folding). It also provides very high levels of resistance to cutting, creep, tearing and abrasion, even under thermal stress : in hot conditions up to 250°C, as well as cold situations up to cryogenic temperatures. In some applications, particularly in composites, the fibre provides vibration damping as well as impact resistance. Vectran®, an "alive fibre" Thermally, what best characterises Vectran® is its resistance to thermal fatigue. As Vectran® is a thermofusible fibre, its resistance decreases with increasing temperature (like all polymers). However, Vectran® recovers all these mechanical performances when the temparture is back to normal, unlike aramids, for example. When exposed to low temperatures, its tensile strength increases (+20% at -80°C). An hydrophobic fibre Vectran® is resistant to detergents and absorbs extremely little moisture.
