A structural component has a main body formed of a fibre composite material, a plurality of first reinforcement parts and a plurality of second reinforcement parts, wherein the main body is formed as a domed body having a peripheral edge and a vertex, wherein the first reinforcement parts are connected to the main body and in each case have a concave curvature course in relation to a first plane, and wherein the second reinforcement parts are connected to the main body and also have a concave curvature course in each case in relation to a second plane.

A composite ballistic panel provides cost-effective ballistic protection against projectiles. The composite ballistic panel comprises a composite ballistic assembly with an impact/strip layer that alters the projectile during striking contact with the projectile by flattening the projectile, distorting the shape of the projectile, reducing rotation of the projectile, reducing the velocity of the projectile, and inducing yaw to the projectile; a non-ballistic deflection layer that forms a cavity to inhibit propagation of the projectile's shock wave; and a containment layer that stops and captures the projectile within the composite ballistic assembly. Additionally, the composite ballistic panel may have a protection layer and a boundary edge to enhance capture of the projectile and ballistic characteristics, and an intermediate layer that acts as spacer between layers.

In various embodiments, an improved flexible-composite material is described that comprises at least one scrim constructed from at least two unidirectional tape layers bonded together and at least one woven fabric, non-woven fabric, or membrane bonded to the scrim. In various embodiments, the unidirectional tape layers comprise a plurality of parallel fiber bundles comprising monofilaments within an adhesive resin. In various embodiments, the fiber bundles are separated by gaps that can be filled in by adhesive or non-adhesive resin.

A multiaxial textile fabric has at least two thread layers and at least one nonwoven layer. Each thread layer is made of multifilament reinforcement yarns arranged parallel to one another and so as to lie adjacently next to one another within the thread layers, wherein at least one thread layer is at least partially directly contacted by the nonwoven layer, and cut-out sections are provided within the nonwoven layer, the cut-out sections having a size of at least 4 mm.sup.2. The multiaxial textile fabric also includes a fiber-reinforced composite material.

A non-wicking underlayment board and methods for forming the same. The non-wicking underlayment board includes a foam core formed of closed cell foam with reinforcement layers encapsulated within the foam core. Outer facings formed of mineral coated nonwoven fibers are positioned on opposite faces of the non-wicking underlayment panel. The non-wicking underlayment board is useful for efficient and cost effective installation of barriers and surfaces in water-resistant and waterproof environments.

An object is to provide a composite material manufacturing method for improving interlayer strength. The present disclosure provides a composite material manufacturing method of laminating a plurality of prepregs (10) formed of a fiber reinforced base material impregnated with an uncured matrix resin and performing hot molding, the method including: using the prepregs (10) each provided with a gap layer (12) that does not contain a resin and is continuous in an in-plane direction and resin layers (11a, 11b) disposed on both surfaces of the gap layer; disposing a plurality of short fibers (13) on facing surfaces of the prepregs (10) that are adjacent to each other; and evacuating the laminated prepregs (10) to degas the gap layer (12) and then performing hot molding.

The present invention relates to a multi-layered sheet suitable as floor or wall covering exhibiting a three-dimensional surface relief and a decorative image, comprising: i. a support layer having an upper surface and a lower surface; ii. a foamed layer having an upper surface and a lower surface, the lower surface of the foamed layer provided adjacent, and adherent to the upper surface of the support layer, the upper surface of the foamed layer comprising a discontinuous chemically embossed relief pattern, wherein the discontinuous chemically embossed relief pattern comprises indentations formed by single or stacked dots of a digitally printed material comprising a foam inhibiting agent; and optionally iii. a decorative layer adhered to the upper surface of the foamed layer; and optionally iv. at least one wear resistant layer provided adjacent and adhered to the decorative layer; and optionally v. a backing layer provided adjacent and adhered to the lower surface of the support layer.

The present invention provides a laminate material having a polyester film and a web of polyester fibers cohesively bonded directly thereto, such that portions of the fibers are bonded to the polyester film and portions of the fibers are free from the polyester film. The invention may also include a glass reinforced polymer layer formed on the laminated facer where the polymer of the glass reinforced polymer layer is commingled with the nonwoven of the laminated facer. The laminate may further include a second polymer layer having a thickness joined to the fiber layer and/or a layer of hot melt adhesive applied to the polyester fibers. Also presented is a composite material having a polyester film, a layer of polyester fibers bonded to the second polymer layer; a second polymer layer joined to the polyester film; and a glass reinforced polymer layer formed on the laminated facer, where the polymer of the class reinforced polymer layer is commingled with the nonwoven of the laminated facer.

The laminated glazing proposed in this invention has an outer glass layer (201) with holes (20) and a thin inner facing glass layer (202) with shorter length dimension whereas the bottom edge (30) does not have holes on it and which does not overlap with the holes (20) in the outer glass layer (201). One or more retention layers (36), comprising reinforcement and adhesive layers, serve to connect the glazing mounting means (32) to both of the glass layers (201, 202) providing a thin laminated glazing with holes (20) that in the event of failure is retained by the mounting means (32).
