LIGHTWEIGHT COMPOSITES TUBES FOR HIGH PRESSURE AEROSPACE HYDRAULIC APPLICATION
A fluid conduit includes a first portion and a second portion disposed at least partially around the first portion. The first portion may include an extruded thermoplastic. The second portion may include a plurality of layers formed via fiber reinforced thermoplastic tape, tows, and/or fabric. The first portion and the second portion may be substantially rigid and may include concentric cylindrical cross-sections. The fiber reinforced thermoplastic tape, tows, and/or fabric may include nano-additives and/or micro-additives.
Plastic bags, rolls of plastic bags, and tubular blown film processes of making the same
A process of manufacturing a roll of plastic bags. The process includes forming a tubular blown film, and collapsing the tubular blown film so that the tubular blown film includes a first side, a second side, a first edge, and a second edge. Openings are cut in the collapsed tubular blown film, and sealing closure mechanisms are inserted through the openings into the collapsed tubular blown film. The sealing closure mechanisms are then fixed to the collapsed tubular blown film.
Bimodal polyethylene copolymer composition and pipe made thereof
A bimodal ethylene-co-1-hexene copolymer composition consisting of a higher molecular weight component and a lower molecular weight component and, when in melted form at 190 degrees Celsius, is characterized by a melt property performance defined by a combination of melt index (5 kg), melt strength, and, optionally, shear thinning properties, and, when in solid form, is characterized by a slow crack growth property performance defined by a combination of strain hardening modulus and accelerated full-notch creep test performance. A pipe consisting of the bimodal ethylene-co-1-hexene copolymer composition. A method of synthesizing the bimodal ethylene-co-1-hexene copolymer composition. A method of making the pipe. A manufactured article, which is not a pipe, comprising the bimodal ethylene-co-1-hexene copolymer composition.
Molding apparatus
A molding apparatus includes an extrusion die having an extruding orifice and a projection forming orifice, and a rotor rotatably installed in a middle portion of the extrusion die and having a forming recess adjacent to the projection forming orifice.
Method for Evaluating at Least One Industrial Process
The invention relates to a method (100) for evaluating at least one industrial process for the film production of a film and/or for the further processing using the film, comprising at least one production device (20) which is operated for the production of the film, and at least one further processing device (30) which is operated for further processing using the film.
STAND-UP PLASTIC STORAGE BAG WITH REINFORCED BOTTOM GUSSET
A stand-up plastic food storage bag having two bottom gusset walls and a folding seam defining abutment of the front bottom gusset wall to the rear bottom gusset wall. There are gusset wall reinforcement layers on an external surface of the bottom gusset walls, and these reinforcement layers terminate at least about 0.25 cm away from the folding seam, and do not cover the folding seam, so they do not significantly interfere with folding the seam when collapsing the bag into its storage condition. A method for forming such stand-up plastic food storage bags by coextruding a monolayer plastic panel film and two monolayer plastic gusset floor reinforcement layers, wherein the monolayer plastic gusset floor reinforcement layers comprise two parallel strips spaced apart by at least about 0.25 cm on the panel film, lengthwise in a direction of coextrusion, followed by folding the monolayer plastic panel film lengthwise to form a lengthwise fold line between the two monolayer plastic gusset floor reinforcement layers, forming a gusset in the area of the lengthwise fold line, forming seals in the plastic panel film in a direction perpendicular to the lengthwise fold line to define individual bag segments, and cutting the plastic panel film at the seals to form individual stand-up plastic food storage bags.
Fabrication and application of nanofiber ribbons and sheets and twisted and non-twisted nanofiber yarns
A nanofiber yarn that includes a plurality of nanofibers twisted into a yarn along an alignment axis. The nanofibers of the plurality of nanofibers have a ratio of nanofiber length to nanofiber circumference of at least 50. The yarn has a helix angle measured relative to the alignment axis of from 5? to 30?. The yarn has tensile strength of at least 280 MPa. A nanofiber fabric that includes a first sheet of multiwalled nanotubes and a second sheet of multiwalled nanotubes on the first sheet of multiwalled nanotubes. The multiwalled nanotubes of the first sheet are aligned in a first direction. The multiwalled nanotubes of the second sheet are aligned in the first direction. The first sheet and the second sheet are aligned so that the multiwalled nanotubes of the first sheet and the second sheet are both aligned in the first direction.
Plastic corrugated tube for surrounding pipes and method for producing such a corrugated tube
A plastic corrugated tube having corrugations distributed over its length and a longitudinal slit running along a lateral longitudinal line is provided. The corrugated tube can be converted into an open position by opening the longitudinal slit and into a closed position in which edge regions of the corrugated tube overlap, wherein the corrugated tube is elastically prestressed toward its closed position. The corrugations on the edge region of the corrugated tube, which in the closed position lies radially below the other edge region of the corrugated tube, are offset radially inwards within a predefined circumferential region with respect to the corrugations outside this circumferential region and are designed such that, in the closed position, they are in engagement with the radial underside of the corrugations of the other edge region, which corrugations engage over them such that they are mutually displaceable in the circumferential direction.
Wire harness routing aid
Method and apparatus are disclosed for a wire harness routing aid. An example wire harness routing aid for a vehicle includes an extruded core made of a thermosetting polymer. The example wire harness routing aid also includes a plurality of wires positioned around an exterior of the extruded core. Additionally, the wire harness routing aid includes a fastening layer to affix the plurality of wires to the extruded core.
Roof ditch molding assembly and process with heated air assist
A method and assembly for reshaping an elongated plasticized article including a pair of first and second spaced apart fixtures adapted to supporting extending ends of an elongated article. The fixtures each exhibit a contoured upper surface upon which the elongated article is adapted to being supported in adhering fashion. A heated airflow is delivered in communication with at least one surface of the article and, upon cooling, the article exhibits an extending profile matching the contoured upper surface. A pre-heat station pre-softens at least an extending subset portion of the article prior to transfer to the fixture. Pluralities of gripping fingers communicate with an underside of the contoured upper surface and are adapted to engage at least underside accessible cross sectional profile locations of the article.
