A structural reinforcement for an article including a carrier that includes: (i) a mass of polymeric material having an outer surface; and (ii) at least one consolidated fibrous insert (14) having an outer surface and including at least one elongated fiber arrangement having a plurality of ordered fibers arranged in a predetermined manner. The fibrous insert is envisioned to adjoin the mass of the polymeric material in a predetermined location for carrying a predetermined load that is subjected upon the predetermined location (thereby effectively providing localized reinforcement to that predetermined location). The fibrous insert and the mass of polymeric material are of compatible materials, structures or both, for allowing the fibrous insert to be at least partially joined to the mass of the polymeric material. Disposed upon at least a portion of the carrier may be a mass of activatable material.

Disclosed herein are a method for manufacturing a metal-polymer hybrid part, the metal-polymer hybrid part itself, and a laminate component. The method includes the steps of (a) providing a laminate component containing at least one metallic layer covered by at least one first functional layer, (b) providing a polymeric component, (c) bringing into contact the polymeric component with the at least one first functional layer of the laminate component, (d) joining the polymeric component onto the at least one first functional layer by physical treatment and (e) obtaining the metal-polymer hybrid part.

The present invention relates to a container having a cavity, wherein the cavity has a cavity pressure and comprises fibre material suitable for manufacturing one or more fibre-reinforced composite components for a wind turbine blade, and at least a part of the fibre material touches a first part of a wall of the container, at least the first part of the wall consisting of a flexible airtight material, and a ratio of an entire volume of non-cured polymer in the cavity to an entire volume of the fibre material in the cavity is less than 0.3, and the container is adapted to prevent inflow of a polymer into the cavity. A method for preparing such a container is also disclosed. A method for laying fibre material into a mould is also disclosed.

A construct for a hockey skate outsole formed from layers of sheet molding compound material. The sheet molding compound material may be manufactured to have shorter average fiber lengths with random orientation in order to enhance the mechanical properties of the formed hockey skate outsole.

The invention relates to a pellet comprising a thermoplastic polymer sheath intimately surrounding glass filaments, which glass filaments are covered at least in part with an impregnating agent and extend in a longitudinal direction of said pellets, wherein the thermoplastic polymer sheath is prepared from a thermoplastic polymer composition comprising A) a heterophasic propylene copolymer consisting of a propylene-based matrix and a dispersed ethylene-α-olefin copolymer, wherein the heterophasic propylene copolymer has a melt flow rate of at least 40 g/10 min as determined in accordance with ISO 1133 (230° C., 2.16 kg) and a FOG value of at most 350 μg/g as determined by VDA 278, wherein the glass filaments are present in an amount of 10-70 wt % based on the pellet.

Extruded molds and methods for manufacturing composite structures using the extruded molds are disclosed. The molds may include recessed or raised longitudinal features to impart a corresponding shape to the molded composite structures. The composite structures may be panels used to construct cargo vehicles, for example.

An agricultural stake to support plants includes a fiberglass reinforced plastic (FRP) elongated member comprising a top end and a bottom end, and a textured exterior surface. The agricultural stake includes an elongated member comprising a thin walled tube having a top end and a bottom end, and the elongated member comprises fiberglass reinforced plastic and exhibits no flex memory. The elongated member has an exterior surface texture configured to provide purchase to a line attached to the elongated member, where the exterior surface texture is formed by an abrasive.
