The concentric layers include: (a) an inner layer of a corrosion protective material substantially along and surrounding the length of the core substrate; (b) a layer of a first protective plastic coating surrounding the corrosion protective material; (c) a layer of a heat-resistive intumescent coating surrounding the first protective plastic coating; (d) a layer of a reinforcing mesh embedded in or on the intumescent coating; and (e) an outer layer of a second protective plastic coating.Type: GrantFiled: November 17, 2000Date of Patent: August 26, 2003Assignee: Structural Technologies, LLCInventor: John R. Crigler

Patent number: 6607851Abstract: A multi-layer tile material produced from layers of alumina enhanced thermal barrier material having different densities. The insulation layers are bound together by a high strength, high temperature alumina or silica binder having a coefficient of thermal expansion similar to that of the insulation layers. Use of the multi-layered tile allows the problems of tile slumping and of insufficient heat management associated with low density alumina enhanced thermal barrier tile to be overcome.Type: GrantFiled: October 26, 2001Date of Patent: August 19, 2003Assignee: The Boeing CompanyInventors: Robert A. DiChiara, Jr., Franklin K. Myers

Patent number: 6596658Abstract: A laminated fabric consisting of a relatively lightweight layer formed of dimensionally stable, heat-resistant fibers, and a relatively heavyweight layer formed of one of more plies. The laminate is imaged on a three-dimensional support surface, and the laminate may be treated with a fire-retardant binder to stabilize the image and enhance the flame-retardant properties.Type: GrantFiled: January 24, 2000Date of Patent: July 22, 2003Assignee: Polymer Group, Inc.Inventors: Michael J. Putnam, Herbert P. Hartgrove

Publication number: 20030129902Abstract: A textile product with enhanced flame and/or smoke retardant properties and a method of forming the same is disclosed. The textile product is comprised of a textile material having a primary layer or backing with intumescent particles coated, sprayed, sprinkled, or otherwise applied to the upper surface thereof. Additionally or alternatively, the particles may be incorporated into the tufting primary or backing. The intumescent particles may also be complexed with additional agents, such as antimicrobial agents, softening agents, pliability agent, stain resistant agents, waterproofing agents, static resistance agents and combinations thereof.Type: ApplicationFiled: November 14, 2002Publication date: July 10, 2003Inventors: Connie D. Hensler, Raymond A. Berard
