摘要:
The present invention relates to composite materials and the use thereof as energy resistant, for example blast-resistant, materials. Preferred aspects of the invention relate to layered composite panels comprising solid foam materials which have both a blast attenuation function and an anti-ballistic function. In further aspects, the invention provides novel composite panels which are suitable for use as blast resistant and/or anti-ballistic materials. In some examples described, the layered composite panel comprises a polymeric material (10) bonded to a first solid open-cell foam panel (12), and a cured polymeric material (14) penetrates a surface of the first solid open-cell foam panel (12).

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 and heating to foam and cure the epoxy materials. Alternatively they may be formed by extrusion of the foamable material between the surface layers.

A method for manufacturing a fibre composite component is disclosed. A single-piece foam body or the parts of a multi-part foam body having at least one recess which is open towards a first side of the foam body are prepared and positioned. A rigidifying element for the backing structure or a preform or first semi-finished product for forming the rigidifying element is arranged in the recess at least in portions. A skin portion or a second semi-finished product for forming the skin portion is provided, and brought into contact, in regions, with the foam body on the first side thereof and with the rigidifying element. The skin portion or second semi-finished product and the rigidifying element or preform or first semi-finished product in contact therewith are processed further in such a way that a fibre composite component is obtained in which the skin portion and the rigidifying element are interconnected.

A method for producing an insulated pipe in corrugated casing (100) comprising the steps of: covering an inner pipe assembly (105) comprising at least one inner pipe (101) with a film (106); dispensing an expandable insulation material (102) in a liquid state between the inner pipe assembly (105) and the film (106) thereby preparing an initial pipe assembly (107) comprising a layer of expanding insulation material (102a) positioned between the film (106) and the inner pipe assembly (105); extruding a layer of outer casing (104) onto the initial pipe assembly (105) before the insulation material has expanded completely, thereby creating a still expanding insulated pipe assembly (118); and leading the still expanding insulated pipe assembly (118) through a corrugator (205) having an inner corrugated surface giving the casing (104) a corrugated shape as the at least one layer of expanding insulation material (118) continues to expand.
摘要:
A vehicle door trim panel has a resin core. The resin core has a foam layer and a skin layer that covers the foam layer. The skin layer is harder and thinner than the foam layer. A tape member is applied to the resin core along at least a part of an outer edge of the resin core or along at least a part of a peripheral edge of an aperture of the resin core.

A deformable sandwich panel is disclosed according to one embodiment. The deformable sandwich panel may include first and second face sheets. These face sheets may each comprise a first and second surface and be substantially flat. The deformable sandwich panel also includes a shape memory material sandwiched between the first face sheet and the second face sheet. The shape memory material may be in continuous contact with a substantial portion of the first surface of the first face sheet and with a substantial portion of the first surface of the second face sheet. The deformable sandwich panel may be fabricated with a first shape, deformed into a second shape and then deployed back to the first shape. The first and second shapes may be maintained without mechanical loads.

A lightweight composite fairing bar (14) for use in fabricating a composite component (16) of an aircraft. The fairing bar (14) includes a core (18) and an elongated outer shell (20) surrounding the core (18). The outer shell (20) is comprised of a laminate material, and the core (18) is comprised of epoxy syntactic foam having a lower density than that of the laminate material. The outer shell (20) is configured for supporting the composite component (16) during the manufacture of the same.
