HexPly M9 prepregs enable short cure cycles at 100°C and above and provide an excellent balance between ease of processing and mechanical performance. Available in high tack and medium tack variants, HexPly M9 prepregs are available with a wide range of unidirectional, woven, and multiaxial reinforcements. Partnered with Hexcel’s own HexTow® IMC2 and HexTow® HM54 / HM63 fibers, designers and engineers can optimize highly loaded composite structures such as masts, wing sails, and foils with increased glass transition temperatures (Tg) and excellent long-term fatigue performance.

Hexcel has completed the DNV GL certification for HexPly M9 in response to the rapidly increasing demand for type-approved high-performance prepreg materials for large composite structures in the commercial marine craft.

Hexcel’s collaboration with Chantiers de l’Atlantique on its new Silenseas cruise ship concept – a concept that uses composite Solid Sail® propulsion as well as dual-fuel engines to reduce emissions and operating costs – is one such application. In this case, DNV GL type approval provides third-party assurance of the product’s quality, performance and consistency, and also helps to streamline the approval of composite parts that replace traditionally metallic structures.
