From the background information supplied by the inventors, news correspondents o btained the following quote: “Field “This specification relates to a system, method, robot and/or apparatus for perf orming multi-layer prepreg composite sheet layup. “Description of the Related Art “Robots are used in a wide range of industrial application areas like assembly, sheet lamination based additive manufacturing, robotic finishing and composite m anufacturing. Composites are advanced structural materials consisting of fiber r einforcements with high specific strength and stiffness embedded within an engin eered polymer matrix. High-performance composites are most often produced by lay ing down sheets of “prepreg,” i.e. a sheet of carbon fiber reinforcements pre-mi xed with an uncured, liquid polymer resin on a contoured mold. Multiple prepreg layers may be required to achieve a target stiffness and strength. After layup, the resulting laminate is cured using a prescribed heat and pressure cycle in an autoclave or oven to convert the resin from a fluid into a vitrified solid to m aximize its properties.
