Sky Advanced Materials (Fót, Hungary) announced on July 13 that it has earned DNV-GL type approval for its carbon fiber unidirectional and multiaxial fabrics. The type approval covers fabrics made with Zoltek (Bridgeton, Mo., U.S.) PX35 50k tow carbon fiber, sized for use with vinyl ester and epoxy resin matrix systems in infusion or hand lamination processes.
The certification is a general one, but broadly focused on composites use in wind turbine blades, marine vessels and similar industrial parts and structures.
Dietmar Hoffstedde, director sales and business development at Sky Advanced Materials, says, “Sky have worked diligently to earn this certification from DNV-GL. We are particularly excited by the strong mechanical properties achieved with use of the Zoltek PX35 fabric infused with vinyl ester.”
Says Kamal Al-Rawi, managing director of Sky Advanced Materials, “We expect that this certification will help Sky’s customers appreciate the quality and consistency of the fabrics we produce.”
Next-generation aerospace programs demand higher temperatures for structural and hot-section components, fostering advances in thermoset resin chemistry.
Compared to legacy materials like steel, aluminum, iron and titanium, composites are still coming of age, and only just now are being better understood by design and manufacturing engineers. However, composites’ physical properties — combined with unbeatable light weight — make them undeniably attractive.
As next-generation aerospace programs demand higher service temperatures in structural and hot section components, a variety of polyimides vie for program approval.
