Hexcel’s HexPly® M9 Prepreg receives Type Approval Certification from DNV GL

From March Issue of Compositi Magazine


Hexcel has received the Type Approval Certification of its HexPly® M9 prepreg materials by DNV GL. The addition of the HexPly M9 prepreg range to Hexcel’s already comprehensive DNV GL certified portfolio provides ship and boat builders with optimal prepreg processing options.

HexPly M9 prepregs

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’s collaboration with Chantiers de l’Atlantique

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. It also helps to streamline the approval of composite parts that replace traditionally metallic structures.

Experience in marine industry

Hexcel has supplied advanced composite materials to the marine industry for more than 40 years and manufactures a comprehensive range of DNV GL certified products including:

  • woven reinforcements
  • multiaxial fabrics
  • prepregs
  • adhesive films

Hexcel is committed to developing new composite technologies for the marine sector, helping builders evolve their designs to produce lighter, more fuel-efficient, and a sustainable craft for the future.
