    Abstract: The application relates to a nonwoven composite containing a plurality of solid regions and a plurality of porous regions. The solid and porous regions form a repeating pattern on the surface of the composite. The solid regions contain a solid region nonwoven layer, an optional solid region polymer-fiber infused layer, and a solid region cap layer. The solid region nonwoven layer contains a plurality of first staple fibers and less than about 5% by volume of a first polymer. The solid region cap layer contains the first polymer and less than about 5% by volume of the first staple fibers. The porous regions contain a porous region nonwoven layer and a porous region polymer-fiber infused layer. The porous region nonwoven layer contains a plurality of the first staple fibers and less than about 5% by volume of a first polymer. The porous region polymer-fiber infused layer contains a plurality of pores.

    Abstract: The application relates to a nonwoven composite containing a lofty nonwoven layer and a film. The lofty nonwoven layer contains a plurality of primary fibers and defines a plurality of peak regions and a plurality of valley regions. The film contains a thermoplastic polymer and has a peak film thickness in the peak regions of the layer. The film is present on at least a majority of the second surface of the nonwoven layer. Within the valley regions, the film encapsulates a plurality of fibers from the nonwoven layer. The cross-sectional area fraction of total fibers in the film within the valley regions is at least about 8% and the cross-sectional area fraction of total fibers in the film within the peak regions is less than about 5%.

    Abstract: The application relates to a process for forming a nonwoven composite. The process includes forming a lofty nonwoven layer, obtaining a thermoplastic polymer, and applying the thermoplastic polymer to the second surface of the nonwoven layer, where the thermoplastic polymer is in the form of a molten polymer, semi-molten polymer, or solid film. Next, pressure and optionally heat is applied to the nonwoven layer and thermoplastic polymer, where the thermoplastic polymer and the second surface of the nonwoven layer are subjected to a textured surface forming a plurality of peak regions and a plurality of valley regions in the second surface of the nonwoven layer and embedding a portion of the primary fibers from the nonwoven layer into the thermoplastic polymer within the valley regions. The thermoplastic polymer is cooled forming a thermoplastic film and the nonwoven layer which together form the nonwoven composite.

    Abstract: A fiber reinforced polymer strengthening system having a concrete structural member having at least one outer facing surface. At least one pultruded element is located on the outer facing surface of the concrete structural member, the pultruded element containing a matrix material having a Tg of at least about 110° C. and a plurality of fibers having a tensile strength of at least about 300 MPa and an operating temperature of at least the Tg of the matrix material. Also located on the outer surface of the concrete member and at least partially covering the at least one pultruded element is an inorganic binder comprising an inorganic material having an operating temperature of at least about Tg of the matrix material of the pultruded element.
