Application: Method of realization of an item for aeronautical application with hybrid composite materials by means of additive technology (Patent ID: US20230347578A1)

The patent filed by Leonardo SpA describes a method for creating aeronautical items using hybrid composite materials through additive technology. The process involves designing the product using a three-dimensional mathematical model to define the shape, dimensions, and areas requiring reinforcement based on stress levels. Additive technology is then used to deposit a matrix of polymeric material and reinforcing fibers, followed by the deposition of continuous fibers along specific paths to reinforce areas under stress. The continuous fibers are soaked in the matrix material, and multiple layers can be deposited with continuous fibers arranged accordingly.

Furthermore, the method allows for the deposition of different materials of continuous fibers on each layer, enhancing the strength and properties of the final aeronautical item. The continuous fibers can be synthetic (such as carbon, glass, aramid) or natural, and their orientation is determined by the directions of loads or as specified during the design phase. This innovative approach combines additive technology with hybrid composite materials to create aeronautical items with improved structural integrity and performance, showcasing advancements in manufacturing processes within the aerospace industry.
