An outer skin component for a motor vehicle is designed as a shell component with an outer shell and an inner shell, which are in each case designed as fiber-reinforced plastics shells with a fiber reinforcement embedded into a thermosetting plastic matrix. The fiber reinforcement of the outer shell consists of one or more layers of nonwoven material.

A buffer material is a material including a buffer sheet that contains cellulose fibers and a binding material binding the cellulose fibers and has a sheet shape, and a nonwoven fabric sheet that is provided on at least one surface side of the buffer sheet and is formed of nonwoven fabric, in which the cellulose fibers are aligned in a direction intersecting a thickness direction of the buffer sheet, and the alignment direction of the cellulose fibers is along a direction in which an external force is received.

A decorative and/or functional laminate using a nonwoven glass fibre material impregnated and or coated with a novel mixture of at least styrene maleic anhydride copolymer amic acid and cyanuric acid and melamine to provide opacity and a laminate surface suitable for printing or painting and/or sealing.

An elastic diaper element that includes an elastic layer (1) and at least one layer (2) made of a nonwoven. The elastic element has connection regions (5) between the elastic layer (1) and the non-woven layer (2). The connection regions (5) extend in a preferred direction. The non-woven layer (2) is wavy when the diaper element is in the unstretched condition in order to provide regions (6) as a reserve allowing stretching. The connection regions (5) have an oscillating shape along their extent.

An insulation product includes a first layer of a fibrous insulating material, a second layer of a facing material attached to a first surface of the first layer, and a third layer of a slip sheet material and/or a lubricant attached to a second surface of the first layer. The first surface and the second surface are on opposite sides of the first layer and are parallel to one another. For certain applications, the insulation product may include a layer of a slip sheet material and/or lubricant attached to the first surface of the first layer instead of the second layer of a facing material.

An object of the present invention is to provide a stitched fiber-reinforced substrate material capable of suppressing the formation of microcracks in a fiber reinforced composite material. The stitched fiber-reinforced substrate material of the present invention is a fiber-reinforced substrate material formed by stitching reinforcement fiber sheets made of reinforcement fibers using stitching yarns, and the stitching yarn has a linear expansion coefficient in the fiber axial direction of −1×10.sup.−6 to 70×10.sup.−6/K after being heated at 180° C. for 2 hours and then cooled. The stitching yarn is preferably a stitching yarn to which an organic compound having a polar group is adhered.

The invention relates to a method of forming a biodegradable nonwoven fabric, the nonwoven fabric obtained by this method, and a system of devices for carrying out this method, to be used for the manufacture of cellulosic articles for clean-up work and sanitary products, and medical uses.

The present disclosure discloses a fiber structure, including a plurality of fiber layers. The plurality of the fiber layers are stacked and arranged in a surrounding manner and are impregnated and cured in sequence. The fiber structure of the present disclosure is high in structural strength and low in mass. The present disclosure further provides a gymnastic apparatus force bearing frame, including the above-mentioned fiber structure, which is beneficial to reducing the weight of the gymnastic apparatus force bearing frame, facilitating the movement, transportation, disassembling, and assembling of the apparatus, and reducing the labor burden of an operator.

An overlap production method of using standard coiled material, comprising the steps of: selecting a standard coiled material, designing a pattern, laser cutting according to the design pattern, cutting or reserving spaces for inserting drawn strips, forming by staggering and overlapping each layer of standard coiled material, and inserting partial materials of a standard coiled material layer into an adjacent standard coiled material and fixing it with the partial materials of the adjacent standard coiled material, or inserting the drawn strips into the spaces reserved in each layer, and combining the composition and the base clothing to make a product. The present invention produces the product with the above production method by using standard coiled materials instead of thread or strip materials, which not only achieves the goal of higher production efficiency and lower cost, but also makes the finished products have a new staggered material effect.

A cover window according to an embodiment includes a first layer having a first Young's modulus, and a second modulus layer disposed on the first modulus layer and having a second Young's modulus greater than the first Young's modulus. Each of the first modulus layer and the second modulus layer includes a polymer resin and glass fibers, and a volume ratio of the glass fibers in the first modulus layer is greater than a volume ratio of the glass fibers in the second modulus layer.
