Curing the sealant that holds aircraft windshields in their frames can take up to 48 hours, according Lyon, France-based Sunaero (Hall 2B, Stand C140-158). This can result in maintenance specialists and their airline customers releasing aircraft back to service before sealant is fully cured. While maintenance standards allow such an early release of the aircraft and safety is not at stake, sometimes the windshield has to be sealed again after the next landing, said Fabrice Parodi, Sunaero’s sales and marketing director.
Manufacturers are relying more on composite materials for business aircraft construction thanks to a drop in manufacturing costs and better automation. Largely because of improved curing processes, OEMs are gradually eliminating expensive tooling and slashing the overall number of parts needed for a given aerostructure.
