Yes. It is true. Nowadays, application of plastics is not confined to the usual bags and containers. In December 2009, Boeing 787, the aircraft that utilizes plastic composites in its various parts (even the fuselage) had its maiden flight. Boeing 787 can carry 200 to 300 passengers and boasts its ability to save up to 20% in fuel consumption. The unmatched fuel efficiency of its aircraft is caused by the utilization of composites which are relatively light materials. According to Boeing, composites make up about 50% of the 787’s primary structure. Boeing 787 can even compare to today’s fastest wide bodies by reaching speeds of Mach 0.85.
