Syensqo and Bell join forces to industrialize composite part manufacture

Leveraging DDF technology and CYCOM® EP2750 fast cure prepreg to deliver unmatched operational and sustainable benefits

Alpharetta, GA, November 4, 2025 - Syensqo, a global leader in advanced materials, and Bell Textron, Inc., an aerospace and defense company, have joined forces to accelerate the industrialization of composites.

Bell is the early adopter of Syensqo’s patented DDF[1] manufacturing process, coupled with its fast cure aerospace prepreg CYCOM® EP 2750[2].

Bell qualified and industrialized this technology quickly, achieving high-rate production of aerospace composite parts. Implementing this new process has brought major benefits such as decreased operational costs while generating positive environmental aspects such as reduced waste, energy consumption and green-house gas emissions. In addition, DDF enabled the relief of autoclaves’ usage for curing small to medium size parts allowing their utilization for larger parts.

“After more than 30 years our Syensqo-Bell relationship continues to bring innovative solutions to benefit the composite industry”, said Marc Doyle, Business Executive Vice-President of Syensqo Composite Materials. “Syensqo's customer support model is based on the belief that design, material and manufacturing are all inter-related and key to a successful increase in composites adoption. Our teams are structured to support this model and customer collaborations are fundamental in working towards a more industrialized composites industry”.
