A method of manufacturing a connector for a fluid transfer conduit comprises: manufacturing a tube which runs parallel to a central axis C from fibre-reinforced polymer, said tube comprising a hub portion 206 and a flange-forming portion 208 located adjacent to the hub portion 206, wherein the hub portion 206 comprises continuous circumferentially oriented fibre-reinforcement 210; and the hub portion 206 and the flange-forming portion 208 comprise longitudinally oriented fibre-reinforcement 212 which runs continuously from the hub portion 206 into the flange-forming portion 208; and bending the flange-forming portion 208 away from the central axis C such that it extends from the hub portion 206 at an angle to the central axis C.

Provided are composite feedstock strips for additive manufacturing and methods of forming such strips. A strip may include continuous fibers extending parallel to the principal axis of the strip. The cross-sectional distribution of these continuous fibers may be uneven. Specifically, the fibers may be concentrated near the center of the strip and may be positioned away from at least some portions of the strip surface. A strip may be formed by laminating a layup of one or more fiber-containing plies and one or more of resin plies. The position of the different types of plies in the layup is used to control distribution of the fibers and other materials within the strip. The laminated sheet is slit into multiple strips in a direction parallel to the continuous fibers. The cross-sectional profile of the slit strips may be later changed without disturbing orientation of the continuous fibers.

Provided is a method for fabrication of a profile for a spar cap for a wind turbine blade, wherein the profile is fabricated in a pultruding process using one or more strands and/or layers of unidirectional fibres or rovings of unidirectional fibres arranged along a longitudinal direction of the profile and a tool for moulding of the fibres, wherein one or more additional fibres or rovings of additional fibres are introduced in the pultruding process prior to the moulding, wherein the additional fibres are arranged under an angle to the unidirectional fibres, and/or wherein one or more surficial fibres or rovings of surficial fibres are introduced in the pultruding process after the moulding, wherein the surficial fibres are arranged on the outer surface of the moulded profile.

A method of and apparatus for extruding an article of uniform cross-section, the article including a thermoplastic material and at least one cable for inhibiting stretch of the article. The cable is supplied to a respective tube and is conveyed between upstream and downstream ends. The thermoplastic material may be supplied to the downstream end of the tube. The thermoplastic material is brought together with the cable to embed the cable within the thermoplastic material, thereby forming a composite extrudate. The tube is configured to at least hinder movement of loose windings of the cable from the downstream end towards the upstream end, which may prevent or at least reduce incidence of birdcaging.

A fibrous material or composite including a plurality of layers joined to one another, for example, by needlepunching, is disclosed. The fibrous composite generally has an asymmetrical stretch profile, such that the fibrous composite is more extensible in the cross-machine direction than in the machine direction. The fibrous composite may find particular use in forming a cure-in-place pipe liner.

A belt for an elevator system includes a plurality of tension members arranged along a belt width and a jacket material at least partially encapsulating the plurality of tension members defining a traction surface, a back surface opposite the traction surface together with the traction surface defining a belt thickness, and two end surfaces extending between the traction surface and the back surface defining the belt width. A metallic coating layer is applied via deposition of solid particles over at least one end surface of the two end surfaces.

A device for cutting an intermediate product made of rubber, the intermediate product comprising filamentary reinforcing elements embedded in the rubber and parallel to one another, comprises a support, a blade, and a blade holder movable between an open position and a closed position in which the blade comes into contact with the support. The blade is loosely mounted on the blade holder so that the blade is pivotable and/or movable in translation relative to the blade holder.

In one embodiment, a method may comprise heating a composite material into a viscous form, wherein the composite material comprises a thermoplastic and a plurality of reinforcement fibers, wherein the plurality of reinforcement fibers is randomly arranged within the thermoplastic. The method may further comprise extruding a plurality of strands of the composite material, wherein extruding the plurality of strands causes the plurality of reinforcement fibers within each strand to align. The method may further comprise arranging the plurality of strands of the composite material to form an assembly fixture, wherein the assembly fixture comprises an anisotropic thermal expansion property, and wherein the anisotropic thermal expansion property is based on an orientation of the plurality of reinforcement fibers within the assembly fixture.

A method for forming a fiber reinforced thermoplastic part may comprise the steps of locating a thermoplastic material over a mold tool, heating the thermoplastic material to a pliable forming temperature, conforming the thermoplastic material to a mold surface of the mold tool, and depositing a plurality of fiber strips over the thermoplastic material.

Elastic compression apparatus for loose tube used in fiber optic cables, comprising compression contacts for gripping the loose tube following extrusion, the loose tube being made of a first material having a predefined post-extrusion shrinkage, and the compression contacts being made of a second material, wherein the compression contacts are modified to provide a coefficient of friction between the two materials such that said compression contacts apply a radial pressure and an axial tension to said tube that cause elastic deformation only and do not cause plastic deformation. The tube may be extruded at a line speed rate that is relatively different from the optical fiber line speed rate, and causes elastic extension of the tube over the distance that would be covered by post-extrusion shrinkage.
