Abstract

A laminated product () comprises at least: a 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 () of silicone rubber 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. The silicone layer has a thickness, denoted T, of between 1.5 and 3 times the thickness Tof 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.
