US Patent:

20130280476, Oct 24, 2013
Filed:

Mar 26, 2013
Appl. No.:

13/850879
Inventors:

Peter C. Davis - East Aurora NY, US
David L. Spanton - Albion NY, US
Lee D. Markle - Albion NY, US
Philip Steggall - Jamestown RI, US
International Classification:

B32B 5/12
B32B 5/02
US Classification:

428109
Abstract:

A nonwoven laid scrim includes a carrier and an angled scrim overlying the carrier. The angled scrim includes at least one first assembly of filaments and at least one second assembly of filaments. The nonwoven laid scrim has a main direction and a cross direction, the at least one first assembly of filaments is oriented at a first angle, and the at least one second assembly of filaments is oriented at a second angle. Each of the first and second angles is an off-angle measured relative to the cross direction and the first and second angles have distinct values. The nonwoven laid scrim optionally includes a uni-directional fabric including a plurality of filaments, where the carrier overlies the uni-directional fabric. At least two assemblies of filaments and a first cross direction yarn of the carrier also can define a multi-sided shape with at least three sides.

Abstract:

A nonwoven laid scrim includes a first carrier, an angled scrim overlying the carrier, and a second carrier overlying the angled scrim. The angled scrim includes at least one assembly of carbon fiber filaments. The nonwoven laid scrim has a main direction and a cross direction. The at least one assembly of carbon fiber filaments is oriented at an off-angle measured relative to the cross direction. The nonwoven laid scrim optionally includes a uni-directional fabric including a plurality of filaments, where the first carrier overlies the uni-directional fabric.

US Patent:

62969218, Oct 2, 2001
Filed:

Dec 22, 1998
Appl. No.:

9/218189
Inventors:

Phillip W. Blackmore - Fenwick, CA
David L. Spanton - Albion NY
Douglas W. LeVan - Medina NY
Assignee:

Bay Mills Ltd - Ontario
CertainTeed Corp - Valley Forge PA
International Classification:

B32B 306
B32B 512
B32B 502
B32B 526
US Classification:

428102
Abstract:

A lightweight, high-strength composite fabric suitable for use in carpet backing, roofing and membranes and other products which employ rugged fabrics. The composite fabric comprises a layer of nonwoven material disposed between a layer of low shrinkage warp strands and a layer of low shrinkage weft strands. The layers are stitched or knitted together and the resultant fabric may be coated with a resin or sizing to prevent slippage between the several layers of the fabric and impart a measure of stiffness to the fabric. The fabric may be manufactured in sheet or, more preferably, roll form and may be coated with materials suitable for desired end applications, e. g. , bituminous material whereby the fabric may function as a ready-to-use roofing membrane or other high-strength fabric product.
