Reinforcing ply for pneumatoccal casing constituted at least in part by a fabric with a three-dimensional body; tire casings comprising at least one such ply; processes for obtaining these envelopes.
A reinforcement ply intended for use in a tire is characterized by the fact that the reinforcement ply is formed, at least in part, of a fabric having the following properties: (a) the fabric comprises a three-dimensional body and reinforcement threads arranged in the body and held by the body; and (b) practically all the voids in the fabric are capable of being impregnated with at least one material which forms part of the structure of the tire. The invention also relates to these plies which are impregnated with at least one material which forms part of the structure of the tires. The invention further relates to tires having at least one reinforcement ply, as well as to the methods for obtaining such tires.
