摘要： This shaping structure (1) comprises two shaping sheets (5, 7) facing each other at a distance from one another. According to the invention, the shaping structure (1) further comprises a macroporous spacer sheet (9), the spacer sheet (9) being arranged between the two shaping sheets (5, 7) and being corrugated in such a way as to form a series of alternating even peaks (18) and odd peaks (20) distributed in a first direction (D1) of the shaping structure, at least one of the even peaks (18) being attached to the first shaping sheet (5), at least one of the odd peaks (20) being attached to the second shaping sheet (7), each peak (18, 20) attached in this way defining an attachment surface (22, 26) for attachment to the shaping sheet (5, 7) to which this peak (18, 20) is attached.

摘要： A disclosed reinforcer includes a shrinkable layer able to shrink in a direction of shrinkage, under the effect of a heat-shrink heat treatment, from an initial state to a shrunk state, a first corrugatable layer, which includes a gridwork of filaments added against the shrinkable layer and connected to the shrinkable layer by connection lines spaced apart and extending transversely with respect to the direction of shrinkage, the first corrugatable layer exhibiting a shrinkage that is substantially zero or that is smaller than that of the shrinkable layer, so that, when the shrinkable layer is in the initial state, portions of the first corrugatable layer, each defined between two consecutive connection lines, are bent over and, when the shrinkable layer is in the shrunk state, the portions of the first corrugatable layer are curved.
