  • Rigid fiber network structures having improved post-yield dimensional recovery, method of making same, and articles incorporating same
    Patent number: 6403196
    Abstract: A rigid three-dimensionally shaped fiber network structure having improved post-yield dimensional recovery is provided. The fiber network structure is formed from a fabric containing (A) at least one oriented, semi-crystalline monofilament yarn made from a first thermoplastic polymer, and (B) a second thermoplastic polymer which effects bonding of the monofilament cross-over points. The fiber network structures are useful in a variety of articles, including sandwich panels, various spacers, drainage systems, and energy absorption structures.

  • Laminated fiber networks
    Patent number: 5972477
    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.

  • Rigid fiber network structures having improved post-yield dimensional recovery, method of making same, and articles incorporating same
    Patent number: 5851930
    Abstract: A rigid three-dimensionally shaped fiber network structure having improved post-yield dimensional recovery is composed of a deformed textile fabric network structure containing: (A) at least one oriented, semi-crystalline monofilament yarn containing a thermoplastic polymer and disposed in the deformed fabric so as to provide a plurality of monofilament cross-over points therein; and (B) a cured crosslinkable resin impregnating the deformed network structure so as to effect bonding of all or substantially all of the monofilament cross-over points.
