Abstract
Laminated fiber network structures having high resilience, good cushioning properties, and excellent impact-resistance include at least one layer of a three-dimensional fiber network material and a second layer, which may be a planar material (e.g. a fabric, film, or sheet) or a second layer of a three-dimensional fiber network material. The surfaces of the two layers face each other and are bonded together at their points of contact. The three-dimensional fiber network material is a fabric made from thermoplastic filaments that are at least 0.1 mm in diameter, where the fabric has an array of projections and optional depressions pushed out of one or both sides of the fabric.
