The invention relates to a strut, such as fiber composite struts used in aircraft or spacecraft, which has a largest possible outer diameter within a cylindrical installation space of the strut. The invention concerns an insert connected to a fiber composite hollow structure, such as a fiber plastic composite hollow structure, where the hollow structure engages an undercut of the insert, wherein the outer region of the fiber composite hollow structure likewise has an undercut and this undercut is filled with a fiber composite jacket, such as a fiber plastic composite jacket, and the inner region of the fiber composite hollow structure has, at least in one subregion, a core connected thereto.

The invention relates to a method for producing a guiding rod for a pump for dispensing a fluid product. The rod includes a cylindrical body surmounted by a head. The method a plastic injection molding step to form the cylindrical rod. The method also includes a step of correcting the shape of an upper end of the rod so as to form the head by creating a shoulder at the level of the junction between the head of rod and body.

A tube arrangement includes a composite tube defining a centerline axis, wherein the composite tube comprises a proximal surface and a distal surface, and an end fitting comprising a first end disposed within the composite tube and a second end extending from the composite tube, wherein an outer surface of the end fitting defines a flared portion defining a terminus of the first end, a lobe portion disposed axially from the flared portion, and a terminating portion disposed axially from the lobe portion, the proximal surface conforms to a geometry of the outer surface of the end fitting, the lobe portion and the flared portion mechanically lock the end fitting to the composite tube to mitigate movement of the end fitting relative to the composite tube.

A composite part is provided and includes a component, a first set of first composite plies with finite lengths and a second set of second composite plies with finite lengths. A respective end of each of the first composite plies is wrapped around the component in a clockwise wrapping direction and includes first fibers. A respective end of each of the second composite plies is wrapped around the component in a counter-clockwise wrapping direction and includes second fibers.

A composite rebar having ridges formed therein by grinding is buffed and/or coated to reduce the surface roughness caused by fibers extending from the rebar.

The present invention relates to a method for continuously manufacturing UHMWPE products comprising:—providing a counter-rotating twin-screw extruder;—feeding UHMWPE powder into a hopper of said counter-rotating twin-screw extruder;—transporting said UHMWPE powder from said hopper through said counter-rotating twin-screw extruder to an outlet of said counter-rotating twin-screw extruder;—further transporting said UHMWPE powder from said outlet of said counter-rotating twin-screw extruder to an entrance of a heat-controlled tooling system for defining the shape of UHMWPE products;—withdrawing said UHMWPE products from an outlet of said heat-controlled tooling system.

A roll rod for a vehicle includes: a front insulator connected to a powertrain; a rod bracket to mount the front insulator on a front end portion of the rod bracket; a case bracket disposed outside the rod bracket and fastened to a vehicle body; a stopping rubber formed at a rear end portion of the rod bracket and disposed in an inner space defined by the case bracket; and a rear insulator formed between the rod bracket and the case bracket, where the rear insulator is secured to an outer side surface of the rod bracket and an inner side surface of the case bracket. The roll rod enhances an insulation rate against vibration of a powertrain and improves durability while reducing manufacturing costs through the simple structure and application of an extrusion molding method.

A mold unit (30) defines an elongate cavity (70) and has an injection inlet port (90) for a viscous material at one end of the cavity and an injection outlet port (92) at the other end of the cavity. The mold unit includes a gas vent formed by a gap (G2) between two parts of the mold unit. The gap extends continuously or intermittently in the length direction of the the mold unit, while penetrating through the mold unit in the thickness direction such that it provides fluid communication between an interior space and an exterior space of the cavity. The gap is shaped such that, although gasses pass through, the viscous material does not pass due to fluidity resistance of the viscous material resulting from its viscosity. As a result, the gas vent acts to block leakage of the viscous material while permitting degassing of the viscous material.

A system (15) for manufacturing a reinforcing element (1) for reinforced concrete comprises a feeder (16) of a reinforcing fiber bundle (2) along a pultrusion path (4), an impregnating device (17) which impregnates the reinforcing fiber bundle (2) with a liquid thermoplastic polymeric resin (6) to obtain an impregnated fiber bundle (2), a forming channel (8) through which the impregnated fiber bundle (2) is conducted, a solidification device (19) of the composite thread (9) forming a solidified thermoplastic fiber-reinforced bar (11), a pulling device (20) which holds the reinforcing fiber bundle (2) taut along the pultrusion path (4), a winder (21) which winds the solidified bar (11) to form a coil (14), a provisional bending device (22) which bends the composite thread (9) not yet solidified or heats the solidified bar (11) to soften it, bends the heated bar (11) and then cools the bar (11) to solidify it again, so as to confer a continuous provisional curvature to the solidified bar (11) in the direction of the subsequent winding in the coil (14).

Use of a fiber composite material connecting portion to connect a tubular fiber composite material structure to a connecting device, wherein the connecting portion has at least one fiber deflecting element in its interior, wherein the course of the long fibers from the fiber composite material component follows the shape of a fiber deflecting portion of a fiber deflecting element, so that the fiber direction thereof is deflected at the fiber deflecting portion, and wherein the long fibers do not completely loop around the fiber deflecting elements with which they are associated respectively, wherein the fiber deflecting elements consist of fiber composite material, for a pressure tank.
