The thermoplastic resin composition can have a solvent resistance of 15 days or more.

The invention embodies an apparatus for producing resin tubes, the apparatus having a hollow supporting structure, wherein an endless carrier strip is windable around the outside of the supporting structure in a plurality of adjacent windings to form a mould.

Provided are a hose excelling in a lightweight property and in fatigue fracture resistance, a method for manufacturing the hose, and a hydraulic pump. The hose includes a tube, an interior of the tube being hollow, continuous carbon fibers and/or continuous glass fibers wound around an outer circumference of the tube, and a thermosetting resin present external to the tube. The thermosetting resin has an elastic modulus from 0.5 to 10 MPa, and the continuous carbon fibers and/or continuous glass fibers are impregnated with at least a part of the thermosetting resin. The elastic modulus of the thermosetting resin is a numeric value determined by: heating the thermosetting resin for 2 hours at a curing temperature of the thermosetting resin; then subjecting the thermosetting resin to thermoregulation for two weeks under a condition of a temperature of 23° C. and a relative humidity of 55%; and then performing a measurement in accordance with JIS K7161:2019.

A method for manufacturing an arrangement for the transport of media includes a base body formed as a blow-molded part and at least one functional element, in which a preform consisting of polymeric material and at least one functional element are provided and arranged in a blow mold, wherein the base body is formed from the preform, wherein the preform bears against the functional element during forming, wherein the blow mold has a first mold element and a second mold element, wherein the base body is formed from the preform between the first mold element and the second mold element, wherein the first mold element and the second mold element bear against the functional element in such a way that excess material produced from the preform in the area of the functional element during blow molding can be removed.

The present disclosure provides a metal-plastic composite pipe compounding device and a compounding process, the compounding device comprising a material conveying apparatus, a workbench, and a support apparatus, a clamping assembly and a heating and cooling apparatus which are mounted on the workbench. The clamping assembly may move on the workbench; the material conveying apparatus moves a pipe to be machined into or out of the support apparatus; the support apparatus supports the pipe to be machined and may drive same to ascend or descend; the clamping assembly clamps and seals two ends of a plastic pipe of the pipe to be machined; and the clamping assembly drives the pipe to be machined to pass through the heating and cooling apparatus. In the present disclosure, a feeding process, a clamping process, heating and cooling processes and a discharging process may be completed in sequence by means of the compounding device.

Electrofusion tape and method for the production thereof for welding together with plastics pipes in particular for use in a fixed-point fastening, consisting of a jacket element preferably of an electrically insulating plastics material, at least one heating element of electrically conductive plastics material and at least two contact elements for supplying electricity to the heating element, wherein the jacket element and the heating element take the form of tapes, wherein the jacket element surrounds the heating element at least in part, wherein the contact elements are arranged in the mutually opposing marginal regions of the heating element and extend parallel to one another along the heating element.

A method and apparatus, for manufacturing a duct for a fluid management system of an aircraft. A filament-fed additive manufacturing apparatus is used to perform the additive manufacturing process. The additive manufacturing apparatus comprises a nozzle, wherein the nozzle receives material in the form of a filament and adds said material to the duct in a location proximate to the nozzle location, and wherein the nozzle moves in a generally helical path relative to the duct.

A system for sequential circumferential deposition of thermoplastic composite prepreg material to layer plies of prepreg tape, allowing the continuous processing of tubular shapes and rods, comprising a floating mandrel; a first heatable folding shoe configured to heat and wrap a first prepreg tape onto the floating mandrel; a first forming tube configured to heat and pultrude the first prepreg tape so as to form a first layer ply of prepreg tape on the floating mandrel; a second heatable folding shoe configured to heat and wrap a second prepreg tape onto the first layer ply of prepreg tape on the floating mandrel; a second forming tube configured to heat and pultrude the second prepreg tape so as to form a second layer ply of prepreg tape over the first layer ply of prepreg tape on the floating mandrel.

An expansion tool includes a housing, a motor supported by the housing, a mandrel, and a drive mechanism configured to convert a rotational input from the motor into translational movement of the mandrel between an extended position and a retracted position. The expansion tool is configured to perform cycles of axially extending and retracting the mandrel. An elapsed time for one cycle of moving the mandrel from the retracted position to the extended position and back to the retracted position defines a cycle time of the expansion tool. The cycle time is one second or less.
