Filed:

Aug 8, 2001

Appl. No.:

09/924629

Inventors:

William J. Hanyon - Salt Lake City UT
Michael R. Chapman - Bountiful UT
Tsai Jung Huang - Taichung, TW

Assignee:

Chapman Thermal Products, Inc. - Woods Cross UT

International Classification:

B01F 600

US Classification:

428362, 428364, 428357

Abstract:

Fire retardant and heat resistant yarns, fabrics, felts and other fibrous blends which incorporate high amounts of oxidized polyacrylonitrile fibers. Such yarns, fabrics, felts and other fibrous blends have a superior LOI, TPP and continuous operating temperature compared to conventional fire retardant fabrics. The yarns, fabrics, felts and other fibrous blends are also more soft and supple, and are therefore more comfortable to wear, compared to conventional fire retardant fabrics. The yarns, fabrics, felts and other fibrous blends incorporate up to 99. 9% oxidized polyacrylonitrile fibers, together with at least one additional fiber, such as p-aramid, in order to provide increased tensile strength and abrasion resistance of the inventive yarns, fabrics, felts and other fibrous blends. The yarns may be woven, knitted or otherwise assembled into a desired fabric.

US Classification:

428364, 428377, 428379, 428394, 428373, 57243, 57244

Abstract:

Fire retardant and heat resistant yarns, fabrics, and other fibrous blends incorporate one or more fire retardant and heat resistant strands comprising oxidized polyacrylonitrile and one or more strengthening filaments such as metallic filaments (e. g. , stainless steel), high strength ceramic filaments, or high strength polymer filaments. Such yarns, fabrics, and other fibrous blends have a superior tensile strength, cut resistance, abrasion resistance, LOI, TPP and continuous operating temperature compared to conventional fire retardant fabrics. The yarns, fabrics, and other fibrous blends are also more soft, supple, breathable and moisture absorbent and are therefore more comfortable to wear, compared to conventional fire retardant fabrics. The inventive yarns may be woven, knitted or otherwise assembled into a desired fabric or other article of manufacture.

International Classification:

G06F 19/00
B32B 31/00

US Classification:

700110, 700117, 156379

Abstract:

A method generally includes electronically accessing positional data defining a defect location on a composite structure, and automatically causing a material placement machine to return to the defect location as defined by the positional data. The method can also include automatically causing the material placement machine to place or lay down material sufficient for repairing a defect at the defect location. Alternatively, the material placement machine may automatically return to a defect location, and then an operator may manually repair the defect at the defect location.

International Classification:

G01N 29/24

US Classification:

73618, 73620, 73635

Abstract:

A hat stringer inspection device permits continuous inspection of hat stringers as one or more probes are moved along the length of the hat stringer. Probes may be magnetically coupled to opposing surfaces of the structure, including, for example, where one of the probes is positioned inside the hat stringer and the probes are magnetically coupled across the surface of the hat stringer. The device may be autonomous with a feedback-controlled motor to drive the inspection device along the hat stringer. Magnetic coupling is also used to re-orient the position and/or alignment of the probes with respect to changes in the hat stringer or shapes, sizes, and configurations of hat stingers.

US Classification:

156425, 156443

Abstract:

Composite sections for aircraft fuselages and other structures, and methods and systems for manufacturing such sections, are disclosed herein. A method for manufacturing a shell structure in accordance with one embodiment of the invention includes applying composite material to an interior mold surface of a tool to form a skin extending 360 degrees around an axis. The method can further include positioning a plurality of stiffeners on an inner surface of the skin. After the stiffeners have been positioned, a vacuum bag can be installed over the stiffeners and evacuated to press the stiffeners and the skin outwardly against the interior mold surface of the tool. Next, the skin/stiffener combination can be cocured to bond the stiffeners to the skin and harden the shell structure.

US Classification:

403187, 244132, 403265

Abstract:

A bonded composite joint may include a base having a foot configured to couple to a member. The base may include a flange extending outward from the foot. The joint further may include a panel having a core positioned between opposing skins, where the skins have inner walls proximate the core and the skins extend outward beyond the core on at least one end of the panel to define a recess between the skins. The recess between the skins may receive the flange. A bonding agent may be used to couple the flange to the inner walls of the panel.
