Method for producing tank with protective member
Provided are a method for producing a tank with an outer surface profile that allows an elastic protective member to be easily and firmly attached to a surface thereof, and also such a tank with a protective member. The method for producing the tank, which includes winding fiber bundles containing an uncured resin component in multiple layers around the outer surface of a liner in a first pitch width so as to form a fiber reinforced resin layer and securely bonding the protective member to a portion of the outer surface thereof, further includes: winding the fiber bundles in a second pitch width wider than the first pitch width so as to form a gap with a required width where no fiber bundle is present between adjacent fiber bundles in winding the fiber bundles to form an outermost fiber bundle layer; shaving off a tip end portion of a projection made of a resin that has cured after bleeding into the gap, with a portion thereof left unshaved so as to form a sharpened portion; and securely bonding the protective member to the sharpened portion while pressing it from above.

Honeycomb core with improved acoustic properties and method for making same
A method for providing a honeycomb core assembly that includes obtaining a honeycomb core having at least first and second cells that each define a cell interior having an open bottom and an open top, contacting the honeycomb core with a liquid foaming adhesive, contacting a hardening agent with the liquid foaming adhesive, and allowing the hardening agent and liquid foaming adhesive to react to harden and form a first barrier member that spans the cell interior of the first cell and a second barrier member that spans the cell interior of the second cell, thereby forming the honeycomb core assembly.
COMPOSITE MATERIALS
Light weight composites with high flexural strength comprise epoxy foam sandwiched between two layers of facing material have high strength and low weight and can be used to replace steel structures. The facing layer may be fibrous material especially glass or carbon fibres, the facing material is preferably embedded into the epoxy matrix. Alternatively they may be matching box structures or concentric metal tubes. The sandwich structures may be prepared by laying up the fibre; coating and/or impregnating the layer with epoxy resin, laying a layer of heat activatable foamable epoxy material, providing a further layer of the fibrous material optionally coated and/or impregnated with epoxy resin on the foamable material ad heating to foam and cure the epoxy materials. Alternatively they may be formed by extrusion of the foamable material between the surface layers.
COMPOSITE STRUCTURES FOR LOCALIZED STIFFENING
A reinforcing device comprising a composite reinforcing patch including a first layer comprising a first activatable material that is flexible and tacky in its green state prior to activation, a second layer comprising a stabilizing material selected from a mesh, a film, a chemical coating, a fibrous or spherical material, or a second activatable material located in planar contact with the activatable material and along the entirety of a first surface of the activatable material, and an optional third layer comprising a mesh, a film, a chemical coating, second activatable material, or a release paper located in planar contact with the activatable material and along the entirety of a surface of the first layer or second layer, wherein upon activation of the activatable material, the presence of the second layer, the optional third layer, or both provides dimensional stability to the activatable material and minimizes shrinking of the activatable material.
