The designer of easy aircraft to use composite fibers in the desired direction, and where exactly in the required quantity. The fibers are embedded in a resin to remain in position and provide the necessary support against deformation. Instead, plywood or sheet metal, which allows only one curvature, creator compound, in which the fibers fixed in two directions. (Son and attack), also incorporated in the resin. This has the advantage of freedom in the shape of double curvature, as shown optimal aerodynamic shape and looks very attractive (aesthetic of the service) required. (more…)
