Sanitary basin moulded part
A sanitary basin molded part, for example a kitchen sink, a washbasin or a shower tray, has a main part (10) that has the shape of the sanitary basin molded part and ensures its mechanical stability. On the visible side of the sanitary basin molded part a covering layer (20) is arranged in at least one surface region on top of the main part (10). The covering layer includes a fibrous tissue (24) saturated with a cured binding agent. A method produces a sanitary basin molded part of this kind.
Device for curing pipeline inner resin linings
A device for curing inner pipeline linings made with the use of a resin compound cured by electromagnetic radiation, the device being equipped with a central polyhedral body provided with LEDs generating the radiation by emitting waves with lengths from the range 200-500 nm, to cause curing of the resin compound. The LEDs are shielded with an element made of a transparent plastic or quartz glass with a body made of monolithic cylindrical solids having along the whole of length of their outside surfaces with radii identical flat facets-chords symmetrically distributed on the surfaces, to which detachably attached are plastic plates equipped with LEDs emitting electromagnetic radiation with definite range of wavelengths.
Method of manufacturing high pressure gas tank
A liner includes dome sections having outer surfaces along an uniform stress surface at both ends in an axial direction, and nozzles are mounted on the dome section by introducing nozzle flanges into pedestal sections of apexes of the dome sections. Then, ring-shaped caps having the same linear expansion coefficient as the liner and inner surfaces in a curved surface shape of outer surfaces of the dome sections and the nozzle flanges are mounted on boundary portions between the nozzle flanges and the pedestal sections. In forming a fiber layer after that, a helical winding layer is formed first by winding a fiber bundle disposed at the dome sections to cover the dome sections while including the nozzle flanges.
SEMI-CONSOLIDATED REINFORCED THERMOPLASTIC PIPE (SC-RTP) WITH COMMINGLED FIBER REINFORCEMENT
A thermoplastic pipe and a method for producing it are described. The thermoplastic pipe includes a hollow inner liner layer, a semi-consolidated core comprising commingled fibers, and a shrink wrap outer layer. The commingled fibers comprise at least one thermoplastic fiber and at least one reinforcing fiber. The semi-consolidated core layer comprises a thermoplastic polymer matrix that is organized along the at least one reinforcing fiber. The method includes winding commingled fibers over the hollow inner liner layer at a designated angle to produce a core layer, covering the core layer in a heat shrinkable wrap, and heating to produce a semi-consolidated core layer. The semi-consolidated core layer comprises a thermoplastic polymer matrix that is organized along the at least one reinforcing fiber.
SEMI-CONSOLIDATED REINFORCED THERMOPLASTIC PIPE WITH PREPREG REINFORCED CORE LAYER
A thermoplastic pipe and a method for producing a thermoplastic pipe are provided. The thermoplastic pipe includes a liner layer, a semi-consolidated core layer comprising a prepreg polymeric fabric layer, and a shrink wrap outer layer. The semi-consolidated core layer comprises a thermoplastic polymer matrix that is randomly distributed across the fabric. The method includes producing a hollow inner liner layer, winding a prepreg comprising a polymeric powder scattered on a fabric over the hollow inner liner layer to produce a core layer, covering the core layer in a heat shrinkable wrap, and heating to produce a semi-consolidated core layer. The semi-consolidated core layer comprises a thermoplastic polymer matrix that is randomly distributed across the fabric.
Method and system for manufacturing hybrid component
The present disclosure relates to a system for manufacturing a hybrid component including a first thermal supplier configured to heat a steel plate, a rolling roll for undercut configured to pressurize the steel plate heated by the first thermal supplier, and to form an undercut on one surface of the steel plate, a first molding roll configured to pressurize the steel plate formed with the undercut to mold the steel plate in a shape of a component to be manufactured, a composite material feeder configured to supply a composite material tape to be seated on one surface of the steel plate formed with the undercut through the first molding roll, and a composite material pressurization roll configured to pressurize the steel plate on which the composite material tape is seated.

Thermoplastic Composite In-Situ Melt Processing Method for Composite Overwrapped Tools
An in-situ melt processing method for forming a fiber thermoplastic resin composite overwrapped workpiece, such as a composite overwrapped pressure vessel. Carbon fiber, or other types of fiber, are combined with a thermoplastic resin system. The selected fiber tow and the resin are prepared for impregnation of the tow by the resin. The resin is melted; and, carbon fiber is impregnated with the melted resin at the filament winding machine delivery head. The molten state of the composite is maintained and is applied, in the molten state, to the heated surface of a workpiece. The portion of the surface being wrapped is heated to the melting point of the thermoplastic resin so that the molten composite more efficiently adheres to the heated surface of the workpiece and so that the uppermost layer of fiber resin composite is molten when overwrapped resulting in better adherence of successive layers to one another.
PIPE LINER AND METHOD OF MAKING AND INSTALLING THE SAME
An eversion liner for lining a pipe includes an impermeable outer portion, inner and outer strength portions inside the impermeable outer portion, and a middle portion including at least one felt layer radially between the inner and outer strength portions. At least one of the inner and outer strength portions is formed from a unitary sheet of strength material that includes parallel chopped strands of fiber. The longitudinal edge margins of the sheet of strength material are positioned in overlapping engagement and joined together by joining structure. The parallel chopped fibers can be oriented transverse to the length of the liner. The joining structure can prevent reduction in a width of the overlapped edge margins as the liner expands during eversion.
Feed device for reinforcing fiber material and method for cutting reinforcing fiber material by using the feed device
A cutting mechanism includes a cutter roll and a rotational driving mechanism for rotationally driving the cutter roll. The cutter roll has a roll body and a blade portion protruding from a peripheral surface of the roll body. The blade portion is formed at a same position on a circumference of the roll body and extends in an axial direction of the roll body. The cutter roll is arranged so that the axial direction is at a predetermined angle with respect to a pull-out direction of the reinforcing fiber material. The cutting mechanism further includes a slide mechanism that displaces cutter roll in the axial direction toward a side in the pull-out direction of the reinforcing fiber material at least when the reinforcing fiber material is cut.
