A350XWB to Use ACG Out-of Autoclave Prepreg

07 June 2011

MTM44-1 prepreg from Advanced Composites Group (ACG) will now be used for the manufacture of wing panels on the Airbus A350 XWB jetliner, marking the first use of OoA processing in a commercial aircraft structure.

Manufacture is presently at the ramp up stage and full production is expected to begin in late 2011. MTM44-1 was extensively used in the EU funded ‘ALCAS’ (Advanced Low Cost Aircraft Structures) program. Led by Airbus and Dassault Aviation, this programme was aimed at defining the design and technologies for low cost aircraft structures.

MTM45-1 and MTM46 are widely used for the manufacture of structural components in military aircraft, UAV’s and general aviation. MTM47, ACG’s latest OoA prepreg development, is said to offer enhanced compression performance comparable with 180°C autoclave systems, combined with excellent hot/wet open-hole compression behaviour. ACG will feature its Out-of-Autoclave (OoA) technology for aerospace structures at the Paris Air Show between the 20th and 26th June 2011.
