New technologies for manufacturing composites

In 1995 the Boeing 777 was breaking fresh ground in various directions. It was the first aircraft to be produced completely by means of CAD on screens instead of on physical models; it is a large aircraft with only two engines; and it is 50% aluminum with 12% of its weight in composites. 18 years later, the Boeing 787 cut the use of aluminum to 20% of its weight but increased the parts in composite materials to 50%. Both the fuselage and wing frames of the Airbus A350 are mainly manufactured of composites and have a proportion of 53% of these materials and 19% of aluminum. See more >>
