A multilayered polymer composite film includes a first polymer material forming a polymer matrix and a second polymer material coextruded with the first polymer material. The second polymer material forms a plurality of fibers embedded within the polymer matrix. The fibers have a rectangular cross-section.

An intermediate transfer body includes: a base layer made of a resin; and a surface layer disposed on the base layer, wherein the surface layer is an integral object of inorganic oxide and contains a black titanium compound dispersed in the surface layer.

A preparation method for artificial leather, includes applying a weaving process. The weaving includes adopting at least two groups of warp or weft yarns, and weaving each group of yarns into a monolayer structure to form at least two monolayer structures. Each of the monolayer structures is woven with some of the warp and/or weft yarns in such layer or with some of the warp and/or weft yarns in another layer to form a number of connecting points, such that at least two monolayer structures arranged in an orderly manner as two laminates are connected with each other by the weaving process, thereby forming a multi-layer integrated base fabric. The method includes bonding the base fabric and a resin layer together to form an artificial leather; and punching holes multiple air vent holes in the leather distributed in the resin layer and base fabric in the thickness direction.

A method is disclosed for manufacture of a composite blade with an airfoil and a root, wherein the blade comprises a core of chopped fibre composite material and a textile composite material encasing the chopped fibre core. The method comprises: forming a blade insert using chopped fibre composite; surrounding the blade insert with a plurality of layers of a textile in a textile composite material; and thermoforming the blade insert and the surrounding textile composite material in a thermoforming mould in order to consolidate the part.

Disclosed herein is a dry, self-supporting fibrous material, the fibers of which have been treated with a binder composition. The fibrous material can be slit into tapes or tows that are suitable for use in an Automated Tape Laying (ATL) or Automated Fiber Placement (AFP) process. This fibrous material is suitable for forming preforms which are configured to receive a matrix resin by resin infusion in the manufacturing of structural composite parts.
