Disclosed are a method for producing a laminate including a step of laminating a resin impregnated fiber reinforced composition layer on a metal member, wherein the method includes a step of forming a resin coating on the metal member and a step of laminating a resin impregnated fiber reinforced composition layer containing a resin impregnated fiber reinforced composition containing (I) 20 to 80% by mass of a polymer having a melting point and/or a glass transition temperature of 50 to 300° C., and (C) 20 to 80% by mass of a reinforcing fiber
(provided that the sum of the component (I) and the component (C) is taken as 100% by mass) via the above resin coating; and a laminate obtained by the method.

Methods of making a composite article are provided herein. The method can include an unwinding step including unwinding a fiber substrate material from a creel at an unwinding velocity and an impregnation step including applying an uncured resin composition to the fiber substrate material to form a resin-fiber material. The method further includes a winding step comprising applying the resin-fiber material onto a shaped surface at a winding velocity and a solidifying step comprising applying heat to the resin-fiber material to initiate an exothermic reaction comprising polymerization, cross-linking, or both of the uncured resin composition. Temperature of the resin-fiber material can be monitored during operation of the method and a polymerization front velocity set point (v.sub.pfs) and an operating polymerization front velocity (v.sub.pfo) can be determined. Parameters can be adjusted to maintain a v.sub.pfo that is substantially the same as the v.sub.pfs. Systems for performing said methods are also provided.

A storage tank for a gas is provided. The storage tank includes a liner defining an internal compartment; a boss coupled to the liner; an interlayer covering a portion of the boss and the liner, the interlayer being non-pyrolyzed and including an interconnected web and pores having a diameter greater than the diameter of a hydrogen molecule and less than or equal to about 2 nm; and an outer shell including a carbon fiber reinforced composite, the outer shell covering the interlayer, except for an interlayer end that is in contact with the boss, so that the interlayer end defines an interlayer ring that is exposed to an external environment. The storage tank is configured so that when gas diffuses through the liner to the interlayer, the interlayer channels the gas out of the exposed interlayer ring. Methods of fabricating the storage tank are also provided.

A method and apparatus for the continuous fabrication of fiber-bundle-based and composite-tape based preforms and preform charges includes a mandrel about which a constituent material, which is maintained under tension, is wound. The tension is insufficient to fully consolidate the wound material.

A method and system for fabricating a composite structure is provided. At least a first layer of reinforcement material is placed on a surface of a tool. At least a first layer of veil material is then wrapped around the first layer of reinforcement material while the first layer of reinforcement material is positioned on the tool to produce a first reinforced ply.

A high-pressure gas storage container includes a liner and a reinforcing layer. The liner houses a high-pressure gas. The reinforcing layer is formed by winding a plurality of strip-shaped reinforcing members around an outer perimeter surface of the liner. The reinforcing members are made of a plurality of reinforcing fibers that are impregnated with a resin. At least a portion of the reinforcing fibers is irradiated with plasma.

A sash (62) of a window opening up to 180 and capable of tilting is mounted onto a fixedly installed frame profile (63) and houses a pair of superimposing sashes that fit tightly therein when in closure position, i.e. an upper stationary sash (65) and a lower movable-divertible sash (64), each of the sashes (64,65) provided with laterally extending shafts (49) for connection with sash (62), roller wheels (50) provided onto the shafts (49) of sash (64) that roll within a predefined path created by insert guide profile members (19) and diverter guide members (66,68) to alternately bring sash (64) in a position of superimposing sash (65) and a position of alignment with the same. Lifting mechanisms (46) provided with a regulatory screw (84) for adjusting the pretension of a spring component thereof and thereby the force required by the user for moving the sash (64) are installed within the vertically extending sides of the sash (62).

A method for producing a high-pressure tank that can reduce the positional deviation of a wound fiber bundle. In the method for producing the high-pressure tank, the fiber bundle impregnated with an uncured thermosetting resin is wound around a liner for housing gas so as to form, on the liner, a reinforcing layer with a plurality of fiber-reinforced resin layers. The method for producing the high-pressure tank includes pressing an edge portion on at least one side along the longitudinal direction of the fiber bundle in the width direction of the fiber bundle to deform the edge portion so as to protrude in the thickness direction of the fiber bundle and thermally curing the thermosetting resin in the edge portion deformed so as to form a protruding portion in the edge portion, and forming the fiber-reinforced resin layers with the fiber bundle with the edge portion deformed.

Helically winding an extruded web to form a wall of a heated hose about a central axis, extruding a bead of plastics material around a heating wire such that the extruded bead comprises the heating wire at a first location within a cross-section of the extruded bead, helically winding the extruded bead onto the wall of the hose to provide a support helix, and exerting tension on the heating wire to draw down the heating wire toward the central axis such that the heating wire migrates radially inward from the first location to a second location within the cross-section of the extruded bead.

A thin ribbon spirally wound polymer conduit and method of forming, wherein a helical reinforcing bead is interposed adjacent overlapping layers of ribbon. Further, a method of continuously forming spirally wound conduit wherein a sacrificial layer, preferably having a different base polymer to that of the conduit, is first applied to the former before the conduit is formed overtop.
