MUMBAI, India, July 7 -- Intellectual Property India has published a patent application (202617069564 A) filed by Compagnie Generale Des Etablissements on June 03, 2026, for Airless Tyre For An Extra-Terrestrial Vehicle Comprising A Tread Made Of Three-Dimensional Fabric.
Inventors include Delmas, Guillaume; Vilcot, Florian; and Batnini, Illyes Number.
The application for the patent was published on July 03, 2026, under issue no. 27/2026.
Abstract: The present invention relates to an airless tyre (1) for an extra-terrestrial vehicle, comprising a tread made of a three-dimensional fabric, for a vehicle capable of travelling in an extra-terrestrial environment at very low temperatures and on surfaces of different kinds. Such an airless tyre comprises, radially from the inside to the outside, a supporting structure (2), which is intended to co-operate with a rim, a shear band (3) and a tread (4). According to the invention, the material of which the tread (4) is made has a tensile Young's modulus E, measured at a temperature of 20°C, that is at least equal to 1 GPa and at most equal to 6 GPa and, measured at a temperature of -196°C, that is at least equal to 1.2 GPa and at most equal to 9 GPa and a maximum tensile stress Sm, measured at a temperature of 20°C, that is at least equal to 25 MPa and at most equal to 150 MPa and, measured at a temperature of -196°C, that is at least equal to 40 MPa and at most equal to 260 MPa, these mechanical characteristics being measured in accordance with standard ASTM D638, and the tread (4) is made exclusively of a three-dimensional fabric (T).
