A fastening component may be the hook portion (910) or the loop portion of a typical fastener. The fastening elements and the base (910) may be unitary or of different precursors. The porous metal layer (915) may be embedded in the base portion (910) of the fastening component, or any backing substrate (930), or therebetween. The porous metal layer (915) may be fully or partially embedded. The porous metal (915) may be an expanded, perforated, woven or nonwoven structure. The porous metal layer (915) may be incorporated into the substrate (930) that is formed from a precursor element that is separate from the base (910), and that is joined to the base (910). The porous metal layer (915) may also be located between the fastening elements, such as the hooks (916) or loops, and a protective cover, part of whose function is to provide foaming material from fouling the fastening elements. The porous metal containing layer (915) may be wholly metal, or it may be a composite of a nonmetal phase and a metal phase. Rather than using a separate substrate (930) layer for anchoring such a fastener into a molded article being molded, a three-dimensional pattern may be embossed on the non-fastening surface of the fastener to aid in securing it to the molded article. |
