The invention is directed to a core material, suitable for use in a closed mold system, based on at least one fibrous web containing a foam-structure within the web, said foam-structure being formed of a plurality of members that are separated from each other by channels, wherein said core material has a compression-resistance of greater than 40% at a pressure of 4 bar and at a temperature that is greater than or equal to 80° C.

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.

The present invention is an artificial tree consisting of a shape such as conical wherein there is an artificial outer layer, e.g. artificial grass, a solidified foam core, and a post molded into the foam core.

Low-density thermoplastic expandable microspheres are disclosed. Various low-density structures, in particular, sandwich panels, based on foam prepared from the low-density microspheres, are also disclosed. Process of preparing low-density polymeric microspheres, per se, and the corresponding low-density structures, based on the microsphere foam, are also disclosed.

The invention relates to a method of producing a sound proofing trim panel comprising the steps of providing an elastically compressible lower layer, heating the lower layer and placing it in a mould to shape it to form a spring layer of a spring-mass type damping system. The method further includes associating the lower layer with an upper layer, to form the mass of the spring-mass system. According to the invention, the lower layer comprises a blend of elastically compressible foam flakes forming at least 80 wt.-% of the lower layer and being mixed with binder fibres. The fibres comprising a core and a sheath that is fusible at a moderate temperature, and the flakes being bonded to one another by means of the fusing of the sheath forming a binder, such that the lower layer takes the form of a bonded foam.

An apparatus including means for being remoldable with application of heat at a predetermined temperature, means for absorbing the remoldable means, and means for enclosing the absorbing means, wherein the enclosing means comprises a substantially sealed enclosing means configured to resist a leakage of the absorbing means saturated with the remoldable means. The apparatus further include a insole implement, in which the insole implement having an insole section and an arch pad area, wherein the arch pad area is operable for accepting the enclosing means, wherein the insole implement is operable for maintaining a molded shape as the heat activated and remoldable resin composition in the sealed chamber implement cools in temperature, and wherein the insole implement is further configured to be operable for being remolded to a different shape by reheating the enclosing means containing the absorbing means saturated with the remoldable means.
