Abstract:
An all-composite assembly such as a composite laminate aircraft empennage has vertical and horizontal stabilizers with differing sets of interlaminar fracture toughnesses and differing stiffnesses to improve flight characteristics. Composite laminate skins are bonded to unitized and stiffened understructure to reduce weight and improve damage containment.
Abstract:
A system that receives nanomaterials, forms nanofibrous materials therefrom, and collects these nanofibrous materials for subsequent applications. The system is coupled to a chamber that generates nanomaterials, typically carbon nanotubes produced from chemical vapor deposition, and includes a mechanism for spinning the nanotubes into yarns or tows. Alternatively, the system includes a mechanism for forming non-woven sheets from the nanotubes. The system also includes components for collecting the formed nanofibrous materials. Methods for forming and collecting the nanofibrous materials are also provided.
Abstract:
The invention relates to a gas barrier packaging laminate (10) having durability to stress crack formation and yet a bending stiffness and good integrity between the laminate layers, comprising outer layers of heat-sealable polyolefin (16, 17), two polymer carrier layers (11, 12) each being coated with a SiOx gas barrier layer (13, 14), wherein the two polymer carrier layers with SiOx layers are laminated to each other by means of an intermediate polymer layer (15), which includes a thermoplastic polymer having high elastomeric properties. The required stiffness of the packaging laminate is obtained by forming a structural sandwich construction with two stiff carrier layers separated by a relatively thick lower density intermediate layer. Preferably, the thickness of the intermediate polymer layer (15) constitutes from about 30 to about 55% of the total thickness of the packaging laminate (10). The invention also relates to a packaging container such as a pouch or similar manufactured from the packaging laminate and to a method of manufacturing of the packaging laminate.
Abstract:
Fabric laminated foam object, on whose open-cell flexible foam surface synthetic load- bearing fabric - or fabric mixed with synthetic fibre - (2) is laminated so, that on one side of the surface of the load-bearing fabric (2) hot-melt adhesive coating (5) is applied, and the hot-melt adhesive coating (5) is arranged between the surface of the open-cell flexible foam object (1 ) and the load-bearing fabric (2), the layered material composition comprising of the load-bearing fabric (2) and the hot-melt adhesive coating (5) has the property of shrinking 0.5-2% of its size during the 120-220 degrees Celsius temperature range of the laminating; and method of manufacturing thereof.
Abstract:
A nonwoven industrial textile for conveying in an industrial process, seaming elements and methods of manufacture. The textile comprises at least first and second layers of film. Each layer comprises protrusions separated by land areas and each defining an aperture for a flow path through the layer. For at least one of the layers, the protrusions comprise a first set having first and second ends integral with contiguous land areas, and at least a second set of protrusions each comprising a first end integral with a contiguous land area and an opposing second end having a configuration selected from a detached free end; and a weakened end portion integral with but detachable from a contiguous land area in response to strain. The construction allows for relative movement of the layers during travel over machine components such as rolls, reducing internal strain and risk of delamination.
