Abstract

Today, the wings of Boeing 787, Airbus A350 aircraft are made by automated laying out of prepregs with subsequent autoclave molding. Boeing and Airbus plan to replace the 737 and A320 aircraft in the coming years, and new materials and technologies need to be developed to ensure the production of these aircraft in the amount of 100 pieces per month. To introduce new processes and materials, research is being carried out on the selection of a binder, reinforcing fillers, development of the vacuum impregnation process, curing and automation in order to increase reliability, speed up the process and reduce cycle time.
