US Patent:

58720677, Feb 16, 1999
Filed:

Mar 21, 1997
Appl. No.:

8/828213
Inventors:

Jian Meng - Pittsburgh PA
Thomas V. Thimons - Allison Park PA
Thomas P. Unites - Library PA
Assignee:

PPG Industries, Inc. - Pittsburgh PA
International Classification:

B32B 708
US Classification:

442387
Abstract:

A needled mat adapted to reinforce a thermoplastic matrix material includes (a) a primary layer having a plurality of thermoplastic fibers in an amount greater than about 20 weight percent of the primary layer on a total solids basis, the primary layer being less than about 20 weight percent of the mat on a total solids basis; and (b) a secondary layer having a plurality of discontinuous glass fiber strands and having thereon a strand coating composition which is compatible with the thermoplastic matrix material, the secondary layer being essentially free of individual glass monofilaments.

Appl. No.:

8/828212
Inventors:

Edward A. Martine - Pittsburgh PA
Jian Meng - Pittsburgh PA
Thomas V. Thimons - Allison Park PA
Thomas P. Unites - Library PA
Assignee:

PPG Industries, Inc. - Pittsburgh PA
International Classification:

B04D 100
US Classification:

442331
Abstract:

A needled mat adapted to reinforce a thermoplastic matrix material to form a composite, the mat including: (a) a plurality of discontinuous glass monofilaments present in an amount ranging from at least about 30 weight percent to about 99 weight percent of the mat on a total solids basis and having a filament coating composition thereon which is compatible with a thermoplastic matrix material; and (b) a plurality of discontinuous glass fiber strands and having a strand coating composition thereon which is compatible with the thermoplastic matrix material, wherein the glass monofilaments and glass fiber strands are essentially uniformly distributed throughout the mat.

US Patent:

59104589, Jun 8, 1999
Filed:

May 30, 1997
Appl. No.:

8/866775
Inventors:

Kenneth D. Beer - Vandergrift PA
Christopher G. Cross - Forest City NC
Thomas V. Thimons - Allison Park PA
Thomas P. Unites - Library PA
Assignee:

PPG Industries, Inc. - Pittsburgh PA
International Classification:

D04H 174
B32B 506
US Classification:

442367
Abstract:

The present invention provides a needled mat adapted to reinforce a thermosetting matrix material to form a composite, composites formed therefrom, and methods related thereto. The needled mat includes a primary layer of a plurality of unidirectional continuous glass fiber strands coated with a composition which is compatible with the thermosetting matrix material and a secondary layer positioned thereon of a plurality of randomly oriented, generally continuous and/or chopped glass fiber strands coated with a composition which is compatible with the thermosetting matrix material. The mat has a total surface weight ranging from about 1300 to about 11,500 grams per square meter.

US Patent:

62390503, May 29, 2001
Filed:

Oct 30, 1998
Appl. No.:

9/183570
Inventors:

Kami Lammon-Hilinski - Aspinwall PA
Anastasia Morfesis - O'Hara Township PA
Thomas P. Unites - Library PA
Assignee:

PPG Industries Ohio, Inc. - Cleveland OH
International Classification:

B04D 100
US Classification:

442180
Abstract:

A matrix for use in a method of photocatalytically decomposing organic compounds in a fluid includes a fiber glass mat substrate carrying a photocatalytic material. The fiber glass mat is made of randomly oriented glass fibers that have been substantially filamentized and needled whereby the filaments are interlocked. Adhesion of the photocatalytic material to the substrate is provided without requiring heat cleaning of the fiber glass by controlling the organic content of the fiber glass mat to be less than 1. 0 percent by weight as measured by loss on ignition. This is achieved by using sizing compositions that preferably have little or no film forming polymer content.

US Patent:

59086890, Jun 1, 1999
Filed:

Jan 24, 1997
Appl. No.:

8/787735
Inventors:

David E. Dana - Pittsburgh PA
Edward A. Martine - Pittsburgh PA
Steven J. Morris - Sarver PA
Thomas P. Unites - Pittsburgh PA
Assignee:

PPG Industries, Inc. - Pittsburgh PA
International Classification:

B32B 702
US Classification:

428219
Abstract:

The present invention provides a mat adapted to reinforce a thermosetting matrix material to form a composite, composites formed therefrom, and methods related thereto. The mat includes a primary, supporting layer having a plurality of randomly oriented essentially continuous glass fiber strands. The primary layer has about 1 to about 10 weight percent of the mat on a total solids basis. The mat also includes a secondary layer positioned upon and supported by a surface of the primary layer, the secondary layer including a plurality of glass fiber strands. The mean average length of the glass fiber strands of the secondary layer ranges from about 20 to about 125 millimeters. The strands of the primary layer are entangled with the strands of the secondary layer by needling the primary layer and the secondary layer together.
