Abstract:
Gypsum panels, sheathing systems, and methods of making and using the same are provided. A gypsum panel includes a gypsum core associated with a first fiberglass mat having a continuous barrier coating, the coating penetrating a portion of the first fiberglass mat opposite the gypsum core, wherein gypsum penetrates a remaining fibrous portion of the first fiberglass mat such that voids in the first fiberglass mat are substantially eliminated. A building sheathing system includes at least two gypsum panels and a seaming component to provide a seam at an interface between the gypsum panels.

Abstract:
A sizing composition includes a texturing agent, a film-forming agent, and organic particles dispersed therein. A glass fiber strand is formed from a plurality of individual glass fibers coated with the sizing composition. A thermoplastic composite material includes such glass fiber strands.
Abstract:
Monolithic gravity-laid inorganic fiber webs that are greater than about 5 cm in thickness are disclosed. Methods of making and using such webs are also disclosed. The gravity-laying process comprises mechanically separating inorganic fibers and collecting the fibers as a monolithic thick web, and may comprise blending of multiple types of inorganic fibers and/or blending of inorganic particulate additives with the fibers.
Abstract:
A fiber sizing formulation includes (1) a nanoparticle (NP)solution that includes a dispersion of transition metal nanoparticles (NPs) in a solvent and (2) a first fiber sizing agent. The NPs disperse throughout the first fiber sizing agent after application of the fiber sizing formulation to a fiber and removal of the solvent. The NPs serve a function selected from a secondary sizing agent, a catalyst for further nanostructure growth on the fiber, and combinations thereof. A fiber includes a sizing disposed about the fiber. The sizing includes transition metal nanoparticles dispersed throughout the sizing. A method includes applying the sizing formulation to a fiber during manufacture of the fiber, and removing the solvent from the applied formulation. A method includes adding a solution of transition metal NPs to a sizing-coated fiber and baking, whereby the sizing solution of NPs is added before baking the sizing.

Application à la réalisation de structures et de matériaux composites pouvant être chauffés par effet Joule ou pouvant être utilisés pour le blindage électromagnétique.
Abstract:
A composite material comprising at least a first layer which comprises a surfactant component, surfactant-generated microcells, a filler component and a binder component; and a second layer which comprises a metallic component. The composite material may further comprise a substrate to which the first layer is adhered. The composite materials have heat insulating, and fire resistant characteristics and are particularly suited for use in building materials and mattresses.
Abstract:
A fibre unit coating apparatus includes a chamber (190) into which an uncured resin coated fibre unit (12) is passed. Microspheres mixed with air are fed into the chamber (190) via ducts (196) and apertures (194a). As a result rapid and even application of the microspheres can be achieved, and the system allows controllable application of the microspheres by varying the rate of flow of the air/microsphere mixture. Positive pressure chambers (72, 74) are provided to prevent the microspheres from blocking the inlet and outlet points where the fibre unit (12) enters and leaves the chamber (190).
