Method and apparatus for extrusion of thermoplastic handrail
A method and apparatus for extrusion of an article is provided. A die assembly can apply flows of thermoplastic material to an array of reinforcing cables to form a composite extrusion. A slider fabric can be bonded to one side of the composite extrusion. After exiting the die assembly, the slider fabric can act to support the extrudate as it passes along an elongate mandrel, which can cause the base of the slider fabric to change shape from a flat profile to the final internal profile of the article. The extruded article can then be cooled to solidify the material. The die can include cooling for the slider fabric and means for promoting penetration of the thermoplastic into reinforcing cables.
LONG FIBER EXTRUSION APPARATUS AND METHOD
A long fiber extrusion apparatus applies a polymer melt to a length of fiber using a die and an extruder where the length of fiber is directed to the die through a glass tube. The transparency of the glass tube enables viewing of the fiber as it is directed through the glass tube to monitor for any difficulties or problems encountered by the fiber passing through the glass tube. The glass interior surface of the glass tube reduces friction between the fiber and the glass surface and thereby reduces abrasion of the fiber and dust produced from abrasion of the fiber inside the glass tube.
VEHICLE LUGGAGE RACK
A vehicle luggage rack rail includes a skin layer including a first polymeric material and defining interior and exterior surfaces. A coating is positioned on the exterior surface of the skin layer. A base layer is coupled to the interior surface and includes a second polymeric material. The base layer defines a void therein and a plurality of fibers extending through the base layer.
APPARATUS AND METHOD FOR MANUFACTURING FIBER REINFORCED PLASTIC PRODUCT
An apparatus and the method for manufacturing a fiber reinforced plastic product may manufacture a fiber reinforced plastic product by using a 3D printing method and enable the fiber reinforced plastic product to have mechanical physical properties against X, Y, and Z-direction loads, by uniformly arranging reinforcing fibers in the X, Y, and Z directions in respect of orientation distribution, and then by spraying a photocurable resin over the reinforcing fibers so that the reinforcing fibers are impregnated with the photocurable resin.
DEVICE FOR LAYING UP A COMPOSITE PRODUCT WITH FIBROUS ROVINGS
Device for laying up a composite product with fibrous rovings made from glass, carbon, aramid and other similar filaments, designed especially for production of composite reinforcements or supporting elements such as the reinforcement of tailgates of personal vehicles, consists of individual unwinding spools (2) of fibrous rovings (21) rotatably arranged around the composite product (1). The unwinding spools (2) are installed on the set of the rotary disc rings (3) which are mounted on a common fixed ring frame (4) and equipped with independent drives (5) with pre-programmed control of direction and speed of their rotation wherein the composite product (1) is during the laying up procedure alternately fixed to individual carrier grippers (8) of at least one program-controlled manipulator (9). In each rotary disc ring (3) as well as in fixed ring frame (4) at least one lateral passage (6) is created for entry and exit of the composite product (1) between the unwinding spools (2).
METHOD AND APPARATUS FOR EXTRUSION OF THERMOPLASTIC HANDRAIL
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.
FORMATION OF THERMOPLASTIC COMPOSITE REBAR
A system for producing rebar includes a pultruding machine configured to receive a flexible rebar preform. The flexible rebar preform includes at least one reinforcement filament, and at least one thermoplastic filament. The at least one reinforcement filament, and the at least one thermoplastic filament are arranged in a selected distribution across a cross-section of the preform. The pultruding machine includes a pulling apparatus, a rebar cutting apparatus, and a bending apparatus. The pultruding machine is configured to heat the flexible rebar preform to a first temperature. The first temperature is greater than or equal to a melt temperature of the thermoplastic filaments. The pulling apparatus is configured to pull the flexible rebar preform through a pultrusion die to form the rebar. The rebar cutting apparatus is configured to cut the rebar at a prespecified length. The bending apparatus is configured to bend the cut rebar to a prespecified bend geometry.
Methods for manufacturing fiber-reinforced polymeric components
Components may be manufactured by co-extruding a polymer filament and a fiber filament from a nozzle. The polymer filament and the fiber filament may be heated within the nozzle, which may couple the polymer filament to the fiber filament. The co-extruded filament may result in long reinforcing fibers which provide strength to the components.
Composite connecting rod, method for manufacturing such a rod and aeronautic ceiling or floor structure incorporating same
A connecting rod comprises a convex elongated body around a longitudinal axis of symmetry and two connecting ends for connecting to adjacent structures. The connecting rod includes two shells with two longitudinal edges that are assembled in these edges and that each have a base of at least one shell web including continuous shell fibers primarily parallel to this axis of symmetry and impregnated with a thermoplastic shell matrix. The connecting rod incorporates at least one assembly web wound around and along the shells, and assembly fibers primarily inclined relative to the axis and impregnated with a thermoplastic assembly matrix remelted in contact with the shell matrix.
Method of manufacturing tank, heat curing method and heat curing apparatus
A method of manufacturing a tank comprises providing a covered liner by winding a fiber impregnated with a thermosetting resin on a liner; and performing a heat curing process that cures the thermosetting resin by heating the covered liner in a heating furnace. The heat curing process comprises controlling the heating to prevent temperature of the thermosetting resin that is changed by the heating from exceeding a heat resistant temperature of the liner.
