For the Boeing 777, twelve percent of the aircraft is composed of composite materials including the tail section. The success experienced in reducing weight and improving structural integrity has led to the utilization of composites in 50% of the structure for the Boeing 787. Prior to prepregs, composite structures were manufactured by wet lay-up, combining resins and fibers in a process that made it difficult to accurately control and reproduce the fiber content throughout a structure. The development of prepreg, in which resin is pre-impregnated into the reinforcements in very precise quantities, partially cured (b-staged) and supplied on ready to cut rolls, ultimately revolutionized the composites industry.
