Experimental evaluation of mechanical compression of lattice trusses made with Ti6Al4V for aerospace use

Abstract

Lattice structures are three-dimensional structures composed of repeated geometrical shapes with multiple interconnected nodes, providing high strength-to-weight ratios, customizable properties, and efficient use of materials. A smart use of materials leads to reduced fuel consumption and lower operating costs, making them highly desirable for aircraft manufacturers. Furthermore, the customizable properties of lattice structures allow for tailoring to specific design requirements, leading to improved performance and safety for aircraft. These advantages make lattice structures an important focus for research and development in the aviation industry. This paper presents an experimental evaluation of the mechanical compression properties of lattice trusses made with Ti6Al4V, designed for use in an anti-ice system. The truss structures were manufactured using additive manufacturing techniques and tested under compressive loads to determine mechanical properties. Results showed that lattice trusses exhibited high levels of compressive strength, making them suitable for use in applications where mechanical resistance and durability are critical, such as in anti-ice systems. We also highlight the potential of additive manufacturing techniques for the fabrication of lattice trusses with tailored mechanical properties. The study provides valuable insights into the mechanical behavior of Ti6Al4V lattice trusses and their potential applications in anti-ice systems, as well as other areas where high strength-to-weight ratios are required. The results of this research contribute to the development of lightweight, efficient, and durable anti-ice systems for use in aviation and other industries.
