Rigid fiber network structures having improved post-yield dimensional recovery, method of making same, and articles incorporating same

摘要

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.
