1. A panel comprising:
a first woven fabric comprising filamentary warp elements, which are substantially parallel to one another and extend in a warp direction, which constitutes a first main direction of the first woven fabric, and filamentary weft elements, which are substantially parallel to one another and extend in a weft direction, which constitutes a second main direction of the first woven fabric, different from the first main direction of the first woven fabric;
a second woven fabric comprising filamentary warp elements, which are substantially parallel to one another and extend in a second warp direction, which constitutes a first main direction of the second woven fabric, and second filamentary weft elements, which are substantially parallel to one another and extend in a second weft direction, which constitutes a second main direction of the second woven fabric, different from the first main direction of the second woven fabric; and
a linking structure comprising n filamentary elements linking the first woven fabric to the second woven fabric, each filamentary element comprising at least one stay, extending between the first and second woven fabrics and linking the first woven fabric to the second woven fabric, each stay i having an at-rest length hi and extending from a point of attachment to the first woven fabric to a point of attachment to the second woven fabric,
wherein each stay of the linking structure has an at-rest length that is substantially equal to a mean hm of the at-rest lengths of the stays, m representing a total number of stays of the linking structure, and
wherein the first woven fabric is plastically deformable in at least one of the first and second main directions of the first woven fabric.
