Abstract:
Embodiments of the present invention provide a self-molding composite system for insulation and covering operations. The self-molding composite system may be cured to form any desired shaped for insulation and covering operations. The composite system comprises one or more layers that may create a rigid layered composite when cured. The one or more layers of the composite system may include a base layer that is a braided, knit, or non-woven fiber based substrate, an interstitial matrix layer, and customizable top coat. The customizable top coat may be a solvent based polymer solution that includes various additives that may include color pigments, additives for additional abrasion protection, additives for thermal protection, and/or additives for creating various textures or visible appearances to the composite system.

Abstract:
Provided is a first reinforcing fiber layer (11) formed of reinforcing fibers which are wound around an outer periphery of a mandrel (20), aligned in parallel to a direction (+θ direction) in which the reinforcing fibers intersect with an annular direction (0° direction) of the mandrel (20), and seamlessly continue in the annular direction of the mandrel (20) by an amount of at least one rotation.
Abstract:
A method for the production of curved thread-reinforced tubular structures composed of rubber layers and of strengthening layers and an accompanying device. In one aspect, the method includes the application of a first rubber layer to the circumference of mandrels driven forward in a feed direction (X) and winding on of a multiplicity of parallel reinforcing threads, having defined thread angles (null) with respect to the feed axis (x), by means of a bobbin creel, to form a first thread ply. The mandrels are led through a rotating deflection element surrounding the mandrels and the reinforcing threads are guided so as to be distributed on the inner circumference. An application of a covering rubber layer may be performed (after the optionally multiple execution of the previous steps, alone or in combination). The mandrels are led through the deflection element of the bobbin creel eccentrically in the region of the deflection element.
Abstract:
The invention discloses a process and an apparatus for coiling a member by radially winding a continuous filament on to a mandrel. It also discloses the member obtained by this process. The apparatus for coiling the filament or thread (36) consists of a fixed frame (1), a shaft (4) rotating about an axis A which is fixed with respect to the frame (1), a device for rotating shaft (4) and a rotary assembly (2) integral with shaft (4). The rotary assembly (2) consists of a chassis (8) fixed to shaft (4) and supporting structure for rotating the mandrel (10) about an axis B attached to assembly (2) and orthogonal to axis A. The shaft of axis A rotates at a higher speed compared with mandrel (10) about axis B.
Abstract:
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).
Abstract:
A toroidal pressure vessel having extremely high pressure resistance has laminated latitudinal reinforcing fiber layers to improve a strength in a latitudinal direction of the pressure vessel. Moreover, putting reinforcing fibers constituting those laminated latitudinal reinforcing fiber layers in continuity enables further improvement of strength in the latitudinal direction of the pressure vessel, for example compared with a case where the reinforcing fibers are divided for each layer.
Abstract:
An object of the present invention is to provide a high-quality fiber reinforced resin member that enables a longitudinal yarn to be laid out, without slipping, around an outer periphery of a mandrel having at least a bent portion, thus allowing both the longitudinal yarn and a diagonal yarn to be evenly laid out, and a method of manufacturing the fiber reinforced resin member, as well as an apparatus manufacturing a fiber fabric for the fiber reinforced resin member. A fiber reinforced resin member 1 includes an elongate fiber fabric formed by braiding a plurality of longitudinal yarns Q, . . . extending in a longitudinal direction of the fiber fabric and a plurality of diagonal yarns P, . . . inclined at a predetermined angle to the longitudinal direction, the fiber fabric being impregnated with resin that is then hardened. The fiber reinforced resin member 1 has at least a bent portion 1″. The longitudinal yarns Q, . . . are spirally wound at the bent portion 1″, in a posture in which the longitudinal yarns are inclined at an angle of, for example, 10 to 15 degrees to the longitudinal direction.
Abstract:
A toroidal carcass is formed using a toroidal frame defined by two annular beads and by a removable outer ring divided into angular sectors; a winding device for feeding a spool, housing a cord, about and through the frame from a first to a last of the angular sectors; and an actuating device, which, before the cord is wound completely, moves the first angular sector into an operating position defining, with the last angular sector, an opening for the passage of the spool.
Abstract:
A method and device for producing a toroidal road vehicle tire carcass having a toroidal frame rotated about its axis in relation to a winding device and defined by two coaxial annular beads and by a removable outer annular element located radially outwards of and centered axially in relation to the two beads, so as to define, with the same, two annular openings; the winding device providing for winding at least one cord about the frame along a spiral path, each turn of which comprises two portions, a first extending outside the frame, and a second extending outside the outer annular element and through both the openings.
