Abstract: A laminated product (10) comprises at least: a layer (1) of silicone rubber, in particular of the high temperature crosslinking type, such as, for example, a silicone rubber of VMQ or PVMQ grade the said layer (1) of silicone rubber being sandwiched between two layers (2) of fibre-resin composite comprising filaments (3) of an inorganic substance (4), in particular glass, embedded in a thermoset resin (5), such as, for example, a vinyl ester resin. The silicone layer has a thickness, denoted T1, of between 1.5 and 3 times the thickness T2 of each layer of fibre-resin composite, which is between 0.25 and 2 mm. Such a laminate may be used in the manufacture of a finished article, in particular of a non-pneumatic wheel or tire.

Abstract: A non-pneumatic elastic wheel (30) defining three perpendicular directions, circumferential (X), axial (Y) and radial (Z), comprises at least: —a hub (31), for example made of metal; an annular band referred to as a shear band (32) oriented in the circumferential direction (X), surmounted by a tread (33); and a plurality of support elements (34) connecting the hub (31) to the annular shear band (32). The annular shear band (32) is formed by a laminate comprising at least one layer of silicone rubber, in particular of the high temperature crosslinking type, such as, for example, a silicone rubber of VMQ or PVMQ grade, the said layer being sandwiched between two layers of fibre-resin composite comprising filaments of an inorganic substance, in particular glass, embedded in a thermoset resin such as, for example, a vinyl ester resin.
