Scientists from Samara University have developed a completely new technology for strengthening fastening elements for aircraft and spacecraft parts. Thanks to additive technologies, strength will increase, and weight will decrease.

Engineers noted that the further growth in the use of composites in aviation requires their use in places where parts are attached, which necessitates the use of embedded elements — special reinforcing components.
The aim of their research was to develop an improved method for designing such elements, which allows using the advantages of additive manufacturing (3D printing). Traditional embedded elements have a simple shape and are manufactured by machining, which makes the structure heavier.
Additive technologies allow creating structures with variable porosity, which significantly reduces weight and improves adhesion to the composite. Our algorithm automates design, providing minimal weight and high strength in areas of stress concentration.
Experiments have confirmed the effectiveness of the algorithm: the use of embedded elements designed according to the developed method increases the bearing capacity of elements by more than two times.
