Substrate incorporating non-woven elements

Abstract

The invention provides a substrate. The substrate includes a plurality of first filamentary members oriented in a first direction. The first filamentary members are arranged in spaced apart relation to one another. The substrate also includes a plurality of second filamentary members oriented in a second direction transverse to the first direction. The second filamentary members are spaced apart from one another. The second filamentary members are interlaced with the first filamentary members to define an open mesh. The substrate also includes a plurality of elongated strips of non-woven material oriented in the first direction. Each of the non-woven strips is positioned between at least two of the first filamentary members and interlaced with the second filamentary members.

AI Technical Summary

Problems solved by technology

Elongated items, such as wiring harnesses for example, may endure harsh environmental conditions in automotive, aerospace and marine applications.

For example, wiring harnesses may be subjected to vibrations during vehicle operation which can cause abrasion of electrical insulation and result in short circuits.

The harnesses may also be exposed to extreme high temperatures due to incident radiant heat, particularly in engine compartments.

Furthermore, the harnesses may be subjected to radio frequency or electromagnetic interference or may be the source of such interference.

Consideration of radio frequency interference is of particular concern when the wiring harnesses are carrying control signals or emit interference which interferes with radio reception.
