In another embodiment a laminate comprises at least two adjacent fiber-reinforced aerogel layers wherein fibers from at least one fiber-reinforced aerogel layer are interlaced with fibers of an adjacent fiber-reinforced aerogel layer.

The present disclosure is generally directed to a primer saturated carrier medium assembly including a carrier medium having a front face and an opposing rear face, a primer saturating the carrier medium between the front face and the opposing rear face, and removable film impenetrable to the primer covering opposite faces of the carrier medium. A method of applying primer to a surface includes applying a face of a primer saturated carrier medium to contact a surface, and curing the primer saturated carrier medium on the surface. A structure includes a primer saturated medium including a carrier medium having a front face and an opposing rear face, and a primer saturating the carrier medium between the front face and the opposing rear face. The structure further includes a surface adhered to the primer on one face of the primer saturated medium.

In an example, a composite structure having a variable gage is described. The composite structure includes a first end having a first gage, a second end having a second gage, which is less than the first gage, a plurality of continuous plies, and a plurality of drop-off plies. Each continuous ply extends from the first end to the second end. Each drop-off ply includes a tip having a tapered shape. Each drop-off ply extends from the first end to a respective position of the tip of the drop-off ply between the first end and the second end. The tips of the plurality of drop-off plies are arranged in a monotonically-inward pattern.

A planar composite material comprises an UD fiber layer A made of discrete reinforcing fiber rovings and a fiber nonwoven layer B made of a thermoplastic nonwoven which may contain reinforcing fibers, wherein the layers A and B are needled to each other.

The present invention relates to a method of producing a coherent growth substrate product formed of man-made vitreous fibres (MMVF), comprising the steps of (vi) providing MMVF; (vii) providing an uncured binder composition; (viii) providing a superabsorbent polymer; (ix) forming a mixture of the MMVF, the uncured binder composition and the superabsorbent polymer; (x) curing the uncured binder composition in the mixture to form the coherent growth substrate product; wherein the uncured binder composition comprises at least one hydrocolloid.

A composite material (and its manufacture) is described that has (i) a first layer comprising an absorbent fiber material that is in contact with the area of use on its first side, (ii) a second layer comprising an absorbent material, said second layer being arranged on the second side of said first layer, wherein a plurality of channels extends through the entire first layer, from said first side to said second side thereof, and further extends into at least a portion of said second layer. This composite is of particular use in wound treatment.

Provided are a seat cover for an automobile and a manufacturing method therefor, the seat cover comprising a surface-treated layer, a cover layer, a soft foam layer, and a rear layer and comprising an embossing pattern formed on the top surface, wherein the soft foam layer comprises 15 to 20 foam cells per unit area of 1 mm.sup.2 of the surface thereof.

The invention relates to a process for producing a coating film, optionally in the form of sheets or slabs, especially for the coating of a carrier layer (3), optionally textile materials and/or peelable polyurethane foams and/or a textile carrier layer (3), wherein the coating film (100) has an optionally multilayer upper layer (1) and a bonding layer (2) bonded thereto and optionally having multiple layers (2′, 2″) for bonding to the carrier layer (3). It is envisaged in accordance with the invention that the bonding layer (2) creates an uncrosslinked, polyurethane layer having thermoplastic properties and having a thickness between 0.080 and 0.500 mm, preferably between 0.200 and 0.500, especially between 0.120 and 0.180 mm, and is bonded to the upper layer (1), and the upper layer (1) is a polyurethane layer which has a one-layer or preferably two-layer structure with an outer layer (1′) and inner layer (1″) and does not have thermoplastic properties, or a non-thermoplastic polyurethane layer which is amorphous or has a predominantly amorphous structure, said polyurethane layer being thinner than the bonding layer (2).
