An example composite building material includes one or more layers of polymeric fibers, binding agent, and optional fillers, and at least one surface layer of resin-impregnated paper disposed above and/or below the one or more layers. The one or more layers can include a core layer with longer polymeric fibers and top and bottom layers with shorter polymeric fibers. A method of manufacturing the composite building material includes forming the one or more layers, applying the at least one surface layer above and/or below the one or more layers, and heating and pressing the combined layers.

Textile reinforcement that can be used for the production of composite parts by pultrusion, including a central layer made from glass fibre segments and polyester, and in which, in the central layer, the glass fibre segments are enrobed with polyester, the central layer including a central reinforcement core surrounded by the glass fibre segments enrobed with polyester, at least one fibre-web surface layer forming one of the external faces of the textile reinforcement.

According to one embodiment, a method of forming a facer includes forming a first layer of nonwoven glass fibers and positioning a second layer of reinforcement fibers atop the first layer of nonwoven glass fibers. The method also includes coating the first layer of nonwoven glass fibers and/or the second layer of reinforcement fibers with a binder composition and pressing the first layer of nonwoven glass fibers and the second layer of reinforcement fibers together between a pair of rollers. The binder composition is then dried to couple the first layer of nonwoven glass fibers and the second layer of reinforcement fibers to form the facer. The first layer of nonwoven glass fibers and/or the second layer of reinforcement fibers are free of a material coating prior to coating of the binder composition.

A thermally bonded filtration media that can be used in high temperature conditions in the absence of any loss of fiber through thermal effects or mechanical impact on the fiber components is disclosed. The filter media can be manufactured and used in a filter unit or structure, can be placed in a stream of removable fluid, and can remove a particulate load from the mobile stream at an increased temperature range. The combination of bi-component fiber, other filter media fiber, and other filtration additives provides an improved filtration media having unique properties in high temperature, high performance applications.
