WebTech minimizes or replaces the traditional Dacron reinforcement by channeling the broader loads into the Load Frame through a web ‘subframe’ of ultra-high molecular polyethylene (ultra-high modulus). This is featured in key areas such as the primary attachment points on the leading edge or the rear attachment points, while also being used to support structural components such as the center strut.
Developed in partnership with Challenge Sailcloth, this unique Ultra PE leading edge composite material is 25% lighter and 10x stronger than traditional fabrics. This allows for 50% higher pressure, creating increased stiffness combined with a thinner leading edge. The result is supercharged responsiveness coupled with sublime handling, and of course the long-term performance you expect from Airush.
UHMWPE fibers (non-branded Dyneema® or Spectra®) are the lightest and strongest fibers commercially available, with a tensile strength 15x stronger than steel. UHWMPE is created by a gel-spun extrusion process which draws out extremely long chains of polyethylene, aligned along a molecular backbone. This alignment effectively transfers load through the fiber for high modulus and strength.
