Flight Design selects Hexcel’s HexPly® M79 carbon fiber prepregs for ultralight aircraft

German ultralightaircraft specialistFlight Design has chosen Hexcel as its key supplieradopting low-temperature curing prepreg intoits aircraft production.Hexcel’s HexPly® M79Carbon Fiberprepregs delivera more consistent final product by ensuring constant material quality and processing parameters and produce a lighter and stronger aircraft at a more competitive overall cost.

Flight Design has always relied heavily on composites for its aircrafts’ ultralight construction and turned to long-term composite materials partner Lange + Ritter, part of Hexcel’s European distribution network, when they began searching for a prepreg material solution. Hexcel and Lange + Ritter created several new product codes specifically for Flight Designand then supplied materials for initial handling trials and prototyping. Hexcel’s HexPly M79 low temperature curing out of autoclave solution was first used in the new F2 prototype.As part of its material supply package, Lange + Ritter also sent a team for on-site training and technical support, allowing the Flight Design production team to get up to speed with prepreg as quickly as possible.

HexPly M79 prepregs can be cured at temperatures as low as 70 ?C for eight hours or 80 ?C for four hours, reducing tooling costs and increasing buildrates. When combined with Hexcel’s innovative air venting Grid Technology, HexPly M79 UD carbon tapes can also be laminated with reduced debulking steps to produce void contents <1% irrespective oflaminate thickness. With consistently low void contents and improved mechanical properties, designers and engineers are able to further optimize highly loaded composite aerostructures.

As more and more of its composite aircraft parts are transferred to prepreg technology, Flight Design is seeing the benefits of its switch to HexPly M79. Lay-up is cleaner and more precise, low temperature oven curing is quick and energy efficient, and the manufacturing process consistently outputs exceptionally high-quality laminates and components.

The long-term strategy is to integrate HexPly M79 across the range, with Hexcel materials lightening the ultralight aircraft at Flight Design even further.

“The materials and technology package from Hexcel and Lange + Ritter has been a big success for us at Flight Design,” comments Daniel Gunther, Managing Director at Flight Design. “When we took the decision to switch to prepreg, we looked at many options but only Hexcel and Lange + Ritter could offer us low temperature out-of-autoclave (OOA) curing, globally respected material quality and the customer service levels we were searching for.”

Fewer pores, greater impact tolerance: Peter Dornier Foundation Prize 2026 honours material research on fibre-reinforced composite components for aerospace industry

Microscopically small pores that form during manufacture, or barely visible impact damage, can severely impair the load-bearing capacity and service life of fibre-reinforced composite components. Two young researchers have presented groundbreaking work in this field and will both be awarded the 2026 Peter Dornier Foundation Prize: Dr.-Ing. Benedikt Neitzel from the Technical University of Ilmenau for his doctoral thesis on pore minimisation in the RTM process, and Johanna Buschmann, M.Sc., for her master’s thesis, completed at the German Aerospace Centre, on the improved impact tolerance of 3D fabrics compared to 2D laminates.

JEC Forum Southeast Asia 2026 highlights Taiwan as a strategic hub for the global composites industry

The third edition of JEC Forum organized in Southeast Asia brought together 350+ participants from 22 countries for three active days of high-level Business Meetings, conferences, and networking, emphasizing Southeast Asia’s growing role in the global composites market. Held for the first time in Taipei from 23 to 24 June 2026, following the successful first editions in Bangkok, JEC Forum Southeast Asia 2026 confirmed its position as the region’s leading business platform dedicated to the composites industry.

Rieter sees Barmag integration on track as orders and sales rise

The first half of 2026 was shaped by the successful completion of the largest acquisition in Rieter’s history. The Man-Made Fiber Division enables entry into the growth segment of man-made fibers and sustainably strengthens Rieter’s market position in the Asia region. The expanded Group is now the world’s leading system supplier for the processing of natural and man-made fibers. In the first half of the year, initial cost savings in material costs and operating expenses have already been realized. The targeted synergies are expected to amount to at least CHF 20 million by the end of the 2028 financial year. Due to the completion of the acquisition on February 2, 2026, the first half of the year for the Man-Made Fiber Division only amounts to five months.
