Abstract: The present invention relates to a process for producing close-to-final-shape moldings from pressing compositions, in which reinforcing fibers, fiber bundles, fiber fabrics, fiber mats and/or random fiber agglomerates based on metal, glass, carbon, nitrogen, silicon and/or boron, one or more binders and, if desired, one or more additives or fillers are mixed to give a pressing composition and pressed in a pressing mold under the action of pressure to give a molding, where a curable carbonizable polymer is used as binder. The invention provides for a cold-curing binder to be used and the curing reaction to be initiated by addition of a catalyst, with pressure only being applied after the curing reaction has commenced.

Abstract: A nonwoven fabric from spun fibers wherein the density of the spun fibers in the fabric varies between strips of relatively high density and strips of relatively low density. The strips extend along the length of the fabric in the machine direction in an alternating pattern, with the high density strips separated from each other by low density strips. The alternating high density and low density strips provide the fabric with a higher percent elongation in the cross direction than in the machine direction. The alternating pattern is achieved through use of a pattern screen defining a plurality of elongated air permeable regions separated by elongated substantially or relatively air impermeable regions, the elongated regions extending in the machine direction in an alternating pattern, with the air permeable regions separated from each other by the substantially or relatively air impermeable regions.

Abstract: An injection mold apparatus having two halves, a core portion and a cavity portion. One or more gas injection devices, such as porous metal devices, are located in either of the two portions of the mold. Once a charge of hot melted plastic is injected into the mold cavity, gas is injected through gas injection devices forcing the hot plastic against the opposite mold half and into any recesses and grooves. Gas seals are formed by the plastic to prevent gas in the mold cavity from reaching the exterior surface of the molded part during shrinkage of the plastic. The centers of mass of the plastic at rib intersections are optimally positioned to eliminate sink marks on the external finished surfaces of the molded parts.

Abstract: A compression molding apparatus includes a mold of a first material having a first coefficient of thermal expansion and a plug of a second material having a second coefficient of thermal expansion different from the first coefficient of thermal expansion. The mold has a cavity into which the plug is placed such that the mold and plug are disposed relative to one another providing a gap therebetween having a first volume for holding a body that at least partially fills the gap when the mold and plug are at a first temperature and for molding the body into a molded product when the mold and plug are subjected to a second temperature that causes one of the first and second materials of the mold and plug to change in size more than the other and thereby change the gap to a second volume different from the first volume and compress the body.
