Abstract: The invention relates to a composite material filament having rheological characteristics suitable for use in additive manufacturing by extrusion, a method for manufacturing a three-dimensional composite product with an additive manufacturing system from a filament of such composite material, and to a three-dimensional composite product obtained by an additive manufacturing system using such composite material. The filament is formed of material comprising semi-crystalline polylactic acid and chemical pulp of wood-based cellulose fibers, wherein the amount of chemical pulp of wood-based cellulose fibers is selected such that sufficient complex viscosity is obtained at melt state, such that upon additive manufacturing by extrusion, composite melt formed of the filament has a ratio of shear storage modulus to shear loss modulus G?/G? equal to or higher than 1.0 at a temperature equal to or higher than 133° C.

Abstract: The invention relates to a fastening member for fastening of elements, which fastening member has at least a first side and a second side, wherein the first side of the fastening member has at least two transversal extensions. The fastening member has at least one longitudinal extension, and at least two holes, in the longitudinal axis of the fastening member. The invention further relates to a system and a method for manufacturing a fastening member used for fastening of elements, and an arrangement and a use for fastening elements.

Abstract: The present invention thus provides a fabric-laminated plastic part and a novel process where the fabric that provides the surface is pre-laminated with a support layer and supplied into a molding process where a plastic substrate component is molded. The fabric surface piece is precisely located and securely bonded by selection of a support layer plastic material having sufficient heat resistance and/or thickness to sufficiently resist melt softening and stretching during the molding process. This process and fabric laminated plastic article are especially suited for preparing thin-wall, articles that need to have precisely located, smooth fabric surface areas corresponding to discontinuities, voids or openings in the underlying molded plastic article.
