To date, COMAC has received 570 orders for the C919. In 2012, Solvay – at the time Cytec – was awarded a long-term agreement to supply high-performance, structural composite and adhesive materials for COMAC’s C919 commercial aircraft via Shanghai Aircraft Manufacturing Company who is responsible for the C919 aircraft’s manufacture:
- In total, nine prepreg specifications and seven adhesive specifications were qualified with Solvay products for the C919 program and were used across the aircraft’s structure. Solvay’s CYCOM® 977-2 and CYCOM® X850 prepregs, toughened epoxy materials ideal for primary and secondary structure applications were utilized on the horizontal stabilizer, rear pressure bulkhead, aileron and flaps. CYCOM® 970 and CYCOM® 7701, two epoxy prepregs producing void-free honeycomb sandwich and monolithic structures were respectively used on the rudder, elevator, winglets, spoiler, wing-to-body fairings and on the radome.
- Various adhesives for metal and composite bonding were also selected.
Carmelo Lo Faro, President of Solvay Composite Materials, said:
“We are proud to support COMAC in their efforts to advance the Chinese aerospace industry, enabling them to position themselves for growth and to use composites successfully on a range of applications on the C919. We look forward to continuing with our collaborative work with COMAC for their future programs”.
