ABSTRACT:
Annular three-dimensional structure formed by regularly criss-crossed filiform elements, divided in a plurality of families of elements occupying the same place within the structure arranged identically within the said structure. In order to have an undelaminatable structure with a selectable space distribution of its mechanical or physical properties, said structure includes two families of helical elements arranged in cylindrical sheets according to helices of identical pitch but of opposite direction, two families of oblique meridian elements arranged in meridian sheets and with opposite inclinations with respect to the axis, and at least a fifth family of radial elements arranged in meridian sheets, or of circumferential elements arranged in cylindrical sheets, or of axial elements arranged in meridian or cylindrical sheets.
