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.

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 band or belt designed as an elongate bearing, traction or drive element running around rollers or pulleys and made of an elastomer material, and preferably provided with embedded reinforcing elements or tension members extending in the longitudinal direction of the band or belt, having the following features: the band or the belt has one or more elongate tubular receptacles embedded in the elastomer material, in the cavity of which electronic components are arranged, preferably sensors, signal processing or control devices and/or transmission devices, the tubular receptacles are embedded in the elastomer material in such a way that their longitudinal axis or the direction of their greatest extent is oriented substantially transversely to the main bending direction of the band or belt.

A method of forming a multi-component composite material additive manufacture apparatus is described along with an apparatus therefor. The process involves laying a plurality of materials as part of the same process with a range of continuous and discontinuous fiber reinforcement options designed to optimize the operational capabilities of a component.

A flexible and oblong blade seal for sealing a gap between a door leaf and an adjacent surface includes A) a flexible outer material and B) a section with the sealing function (the sealing section), in which a barrier of a plurality of substantially parallel metal wires and/or narrow metal strips is embedded in the flexible outer material in such a way, that the wires and/or strips are arranged in parallel to the longitudinal direction of the seal. A method for mounting such seals and a method for producing them.

A feedstock configured for use in an extruder in an additive manufacturing system is configured as a braided comingled tow filament. A method of producing the braided comingled tow filament includes providing a bundle of comingled tow material having a fiber count ranging from about 1,000 fibers to about 25,000 fibers having thermoplastic fibers comingled therewith, wherein the tow material in the filament ranges from about 50 to 75 volume percent and the volume percent of the thermoplastic material ranges from about 25 volume percent to about 50 volume percent. The method includes dividing the length of comingled tow material into sections, twisting each section into a strand to form a plurality of strands of twisted tow material, and braiding together the strands.

A composite filament for use in additive manufacturing such as fused filament fabrication is described along with methods of its construction and use. The composite filament includes a single continuous filament (e.g., a continuous carbon roving) and a polymer (e.g., a high glass transition polymer) in intimate contact. The composite filament is formed through immersion of the continuous filament in a solution of the polymer. The composite filament can be combined with an additional formation material in an additive manufacturing process.

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.

There is provided a lay-up head for applying elongate fibre reinforcement material to an application surface. The lay-up head comprises a support head having a transverse axis, a dispensing mechanism carried by the support head for dispensing elongate fibre reinforcement material, and a roller for pressing elongate fibre composite material against the application surface. The roller is tiltable with respect to the support head such that the roller axis can be angled with respect to the transverse axis of support head. The lay-up head also comprises a holding mechanism operable to hold the roller in a central position in which the roller axis is parallel to the transverse axis of the support head.

Straight plastic profiles from a plastics material and a continuous reinforcement are predominantly produced continuously in a strand, usually by the pultrusion method. As the plastic profile is pulled through a mold, only straight plastic profiles are formed in known pultrusion methods. In the production of plastic profiles using semi-finished products or complex fibrous constructions, congestion of the fibrous constructions or of the semi-finished products, and thus solidification of the material, may arise when entering the mold, such that the process has to be stopped. A method and a device for the simple production of individually molded plastic profiles is provided in that the mold is formed from at least two mold parts that in relation to the cross section of the plastic profile are split and are moved in a temporally offset manner counter to a production direction of the plastic profile along a portion of the plastic profile.
