Preforms including fiber reinforced nodes for use in fiber reinforced composite structures and methods for making fiber reinforced composite structures. Preforms with woven fabric elements extending radially from a common node include at least one reinforcing fiber interwoven between at least two elements and passing through the node. A method of assembling preform structures using the preforms to provide a structure with reinforced nodes.

A heating pad includes a heat pad with an anterior and posterior side. The heat pad includes a first layer, a second layer, and a third layer. The second layer is located in between the first layer and the third layer. The first layer is located on the posterior side, while the third layer is located on the anterior side. The second layer has a wire selectively heated to increase the temperature of the heat pad. The third layer is a reflective material positioned to reflect heat from the second layer towards the first layer, decreasing heat emitted on the anterior side of the heat pad. The heating pad also includes a battery storage section for securing a battery. The battery is in electronical communication with the wire of the heat pad. The heating pad further includes an engagement mechanism to secure the heating pad to a user.

A woven geosynthetic fabric is disclosed having a first weft yarn, a second weft yarn, and a stuffer pick woven in the weft direction of the fabric. A warp yarn interweaves the first and second weft yarns and the stuffer pick. The first weft yarn and the second weft yarn having different cross-sectional shapes. At least a portion of the fabric has a plurality of weft yarn sets with stuffer picks respectively disposed and woven between the weft yarn sets. Each weft yarn set has two first weft yarns and two second weft yarns. One of the two first weft yarns is adjacent one of the two second weft yarns and stacked on the other second weft yarn. The adjacent second weft yarn is stacked on the other first weft yarn.

The present invention relates to fiber glass strands, yarns, fabrics, composites, prepregs, laminates, fiber-metal laminates, and other products incorporating glass fibers formed from glass compositions. The glass fibers, in some embodiments, are incorporated into composites that can be used in reinforcement applications. Glass fibers formed from some embodiments of the glass compositions can have certain desirable properties that can include, for example, desirable electrical properties (e.g. low D.sub.k) or desirable mechanical properties (e.g., specific strength).

A three dimensional woven preform, a fiber reinforced composite incorporating the preform, and methods of making thereof are disclosed. The woven preform includes one or more layers of a warp steered fabric. A portion of the warp steered fabric is compressed into a mold to form an upstanding leg. The preform includes the upstanding leg and a joggle in a body portion. The body portion and upstanding leg are integrally woven so there is continuous fiber across the preform. A portion of the warp steered fabric includes stretch broken carbon fibers in the warp direction, and another portion includes conventional carbon fibers. The warp steered fabric can be woven on a loom equipped with a differential take-up mechanism. The warp steered fabric can be a single or multilayer fabric. The preform or the composite can be a portion of an aircraft window frame.

A pyramidal geotextile fabric comprising two sets of multi-lobe filament yarns interwoven in substantially perpendicular direction to each other, each of the multi-lobe filament yarns having pre-determined, different heat shrinkage characteristics such that, upon heating, the fabric forms a three-dimensional, cuspated profile. A method of stabilizing soil and reinforcing vegetation comprises the steps of placing a three-dimensional, high-profile woven fabric into soil, wherein the fabric comprises two sets of multi-lobe filament yarns interwoven in substantially perpendicular direction to each other, each of the multi-lobe filament yarns having pre-determined, different heat shrinkage characteristics such that, upon heating, the fabric forms a three-dimensional, cuspated profile; securing the fabric to the ground; and, distributing soil and seed onto the fabric such that the section of ground is quickly revegetated and thereby protected from further erosion.

An imitation leather including a three-dimensional textile supporting material and a PVC-based covering that is applied to one side of the supporting material and includes three successively applied layers. The first layer of which is applied directly to the supporting material without an adhesion-promoting glue layer, the second layer of which is embodied as an intermediate layer and applied directly to the first layer and the third layer of which serves as a top layer and is applied directly to the second layer. This invention also discloses a method for producing such an imitation leather and an interior component of a motor vehicle having a visible surface that is composed of such an imitation leather.
