Medical constructs with collagen fibers and gelatin and related collagen fibers. The collagen fibers can be derived from extruded soluble dermal collagen and can include a gelatin film attached to the at least one collagen fiber. The gelatin film can include one or more minerals and has a gelatin concentration of between about 0.1% to about 40% weight per volume.

A veneered element, including a substrate, a wood veneer layer having a first surface and a second surface, the first surface being opposite to the second surface, an adhesive layer adapted to adhere the first surface of the wood veneer layer to a surface of the substrate, wherein adhesive from the adhesive layer is present in a first portion of the wood veneer layer, extending from the first surface of the wood veneer layer into the wood veneer layer, and wherein the second surface of the wood veneer layer is substantially free from adhesive from the adhesive layer. Also, a method of producing such a veneered element).

Composite materials are provided which may include one or more sheets of carbon fibers woven in orthogonal direction bundles; carbon nanotubes embedded within pores between the bundles; and a matrix material in which the one or more sheets and the carbon nanotubes are embedded. In one case, the carbon fibers lie substantially in an x-direction and a y-direction and the carbon nanotubes are oriented substantially in a z-direction, which is substantially perpendicular to the x- and y-directions. Methods for making the composite materials are also provided.

A laying head for manufacturing a three-dimensional preform includes an inlet configured to feed in a plurality of dry rovings. A fiber conveying device simultaneously and mutually-independently conveys, in a fiber supplying direction, the rovings fed-in via the inlet. An outlet is arranged downstream of the fiber conveying device in the fiber supplying direction and simultaneously lays the plurality of rovings on a workpiece carrier to manufacture the three-dimensional preform. A fiber-cutting device is disposed downstream of the fiber conveying device and upstream of the outlet in the fiber supplying direction and cuts the rovings. A nozzle applies a medium onto the rovings. A slit-shaped through gap of the nozzle has a height is equal to the height of the dry rovings in the thickness direction plus a margin that is sufficiently small so as to cause the medium to be forcibly embedded into the dry rovings.

Provided is a melamine decorative board having a milky-white core layer and less warpage. When the melamine decorative board is bonded onto a base plate such as a plywood, a particle board, and a steel board, a color tone of the base plate does not appear through to a decorative layer. Stacked and thermal-pressure-formed are: a resin-impregnated patterned paper as the decorative layer; multiple sheets of a resin-impregnated core paper, as the core layer, produced by impregnating a whitish fibrous base material with a resin liquid including: a condensate of melamine and formaldehyde, and a divalent polyalkylene glycol or a derivative thereof, or a tri- or more valent polyalkylene glycol polyvalent ether, and drying the whitish fibrous base material; and a resin-impregnated backside paper, as a backside layer, produced by impregnating a fibrous base material with a condensate of melamine and formaldehyde and drying the fibrous base material.

The present invention relates to a roll construction of laminated material that inhibits delamination of the polymer layer from a backer film upon unwinding of the roll construction. Particularly, aspects of the present invention are directed to a roll construction of laminated material prepared by a process that includes providing the laminated material having an ion-exchange resin layer, a release film, and a base layer, and feeding the laminated material to a roller to generate the roll of the laminated material. The laminated material is fed to the roller such that a first layer of the laminated material wound around the core includes the inner surface of the base layer of the first layer contacting an outer surface of the core.
