A blanket formed from multiple layers including a fabric layer on the top and a base layer on the bottom where the base layer may include a waterproof coating on at least one side. The blanket may also include an insulation layer and an adhesive scrim layer positioned between the fabric layer and the base layer. The layers of the blanket may be attached using a combination of stitching along with an adhesive to form a blanket that is waterproof and is secured together such that the fabric layer does not move relative to the base layer.

A CIPP liner for repairing a sewer pipe comprises a cover fabric (1) and a base fabric (2) to be attached to each other using needle punch technology, as well as a stretchable plastic membrane (4) attached to the base fabric (2) with a flexible glue (3), into which flexible glue (3) also the with each other mixed fibres (5) of the cover fabric (1) and the base fabric (2) are glued. From this material, a CIPP liner corresponding to the dimensions of the sewer pipe is cut and sewn, the sewing seam of which is further taped.

This disclosure relates to a sewing process of a breathable, reusable, and leak-proof garment multilayered-lining having absorbent, antimicrobial, waterproofing, and steam dispersion functions. Such lining aims at preventing body fluids such as sweat, blood, vaginal fluids, menstrual fluid, urine, breast milk, or post-surgical fluids from leaking. Such a lining provides the absorbent, antimicrobial, waterproofing, and steam dispersion functions. The lining may be sewed or adhered to the garment piece including: men's and women's underwear, shorts, short pants, skirts, pants, bras, shirts, T-shirts, jumpsuits, body shapers, dresses, men's and women's nightwear, etc. The sewing process creates channels for the liquid and creates a non-linear U-shaped structure on the lining to prevent leakage from the sides. The disclosed lining also has a reduced number of layers on its sides due to one of its layers being smaller in width than the other layers, making the coating thinner for the wearer.

A composite panel includes a backing substrate and a first plurality of fiber tows. The first plurality of fiber tows is stitched to a first surface of the backing substrate in a predetermined pattern to form a fiber reinforced insert. A first polymer layer encapsulates the first surface of the backing substrate and the first plurality of fiber tows.

Described is a method of making a densified fiber batt that includes the steps of: a) providing a fiber batt with a first plurality of fibers having a first melting point and a second plurality of fibers having a second melting point different from the first melting point; and b) subjecting the fiber batt to heat and pressure in a static press, thereby forming a densified fiber batt having a first surface and an opposed second surface.

A method for producing a composite tank is disclosed. The tank has a continuous fiber reinforcement, a prismatic shape, and a thickness e for the storage of a pressurized gas in an internal cavity of the tank. The tank comprises fibers extending between two non-contiguous faces of the tank through the internal cavity. The method includes: (i) obtaining a prismatic fibrous preform having a thickness e comprising three-dimensional continuous reinforcements throughout its thickness; (ii) impregnating an outer layer of the preform with a polymer over a thickness of less than of the thickness e so as to constitute a composite outer shell extending over all faces of the prism; and (iii) forming a sealed layer constituting an inner lining, having a thickness of less than 1/10th of the thickness e between the outer shell and the fibrous network contained in the cavity of the tank.

A composite panel includes a backing substrate and a first plurality of fiber tows. The first plurality of fiber tows is stitched to a first surface of the backing substrate in a predetermined pattern to form a fiber reinforced insert. A first polymer layer encapsulates the first surface of the backing substrate and the first plurality of fiber tows.

A personal protective equipment face covering includes at least one layer. Each of the at least one layers includes at least one fabric material. Wherein, each of the at least one layers of the at least one fabric material including an inherently ionic material. Wherein an ionic charge on the inherently charged ionic material comes from a molecular structure, not from electrostatic charge or triboelectricity.

A textured release sheet includes a substrate, which has been electron beam treated, including a top side and a bottom side. A matte surface is formed on the bottom side thereof, wherein the matte surface of the surfacing material is a coating of an radiation curable material applied to the bottom side of the substrate. The coating is an UV curable acrylate mixture applied to the substrate, wherein the UV curable acrylate mixture is irradiated with UV-radiation via an excimer laser emitter to produce a UV-irradiated layer wherein the UV curable acrylate mixture is only crosslinked on the surface thereof, which produces a matting surface through the effects of a micro-convolution.

A carbon fiber reinforced plastic includes: a base portion including a plurality of stacked carbon fiber layers including carbon fibers arranged at least in a single direction; a resin with which the base portion is impregnated; and a carbon yarn, in which the carbon yarn penetrates the plurality of carbon fiber layers.
