A stone paper includes a first material layer and a second material layer. The first material layer includes a first inorganic material, a first plastic material, and an additive, wherein the first inorganic material, the first plastic material, and the additive are mixed together. The second material layer is coextruded on at least one surface of the first material layer, and the second material layer includes a second inorganic material, a nonmetal thermoconductive material, and a second plastic material, wherein the second inorganic material, the nonmetal thermoconductive material, and the second plastic material are mixed together. A manufacturing method of a stone paper is also disclosed herein.

A method to produce a building panel, including: providing a substrate, applying a thermosetting binder in dry form on the substrate for forming a sub-layer, applying a sheet on the sub-layer, and pressing the substrate, the sub-layer and the sheet together to form a building panel, thereby the thermosetting binder of the sub-layer impregnates the sheet from below. Also, a semi-finished product.

Described herein are details for designing and manufacturing enhanced shock and impact resistant helicoidal lay-ups by combining nanomaterials, variable pitch and partial spirals, Thin unidirectional fiber plies, hybrid materials, and/or curved fibers within a ply. The helicoidal structures created in the prescribed manners can be tuned and pitched to desired wavelengths to dampen propagating shock waves initiated by ballistics, strike forces or foreign material impacts and can arrest the propagation of fractures including catastrophic fractures. These enhancements open the helicoidal technology up for use in such applications as consumer products, protective armor, sporting equipment, crash protection devices, wind turbine blades, cryogenic tanks, pressure vessels, battery casings, automotive/aerospace components, construction materials, and other composite products.

A method for providing bituminous backings for the construction industry, includes the following steps obtaining a semi-finished product having a reinforcement to which a bituminous layer is applied, on the outer surface of which inert materials are or are not distributed and/or inside which the inert materials are embedded. The method also includes annealing the semi-finished product, directly following the step of bituminization of the reinforcement or after the step of applying bitumen to the reinforcement so as to embed the inert materials in the bituminous layer, while at the same time drying the outer surface.

Bio-composite pultruded products (100, 104, 107, 110, 114, 117) either in “I” profile or “Plate” profile of higher cross sectional area where said products consisting essentially natural fibres selected from hemp, jute, sisal and. flex as core impregnated with a resin system comprise of at least one resin, curing system comprising a curing agent and an accelerator, a filler, a thinner, pigment or any other additives; encapsulated between bi-directionally and/or uni-directionally oriented synthetic fabric selected from polyester, carbon, aramid, glass, basalt and mixtures thereof impregnated with said resin system are provided. in another bio-composite pultruded products either of “I” profile or “Plate” profile of higher cross sectional area where said products consisting of plank of short fibers bagasse premixed with the said resin system as core is enclosed between the natural fibers selected from hemp, jute, sisal and flex impregnated with the resin system which is further enclosed between bi-directionally and/or uni-directionally oriented synthetic fabric selected from polyester, carbon, aramid, glass, basalt and mixtures thereof impregnated with the resin system. The system and method for the preparations of said bio-composite pultruded products, are also illustrated herein. These products lead to a significant reduction in weight and reduction in density with higher stiffness and bending strength. The present bio-composite products are encapsulated by fabrics in the peripheral area brings more integrity uniformity of jute materials. This leads to a significant cost reduction in a without sacrificing much tensile strength.

A wearable container containing a composite which has an alternating pattern containing groupings of woven fabric and groupings of biaxially oriented thermoplastic films. The composite has a thickness of less than about 5 mm. Each grouping of woven fabric contains at least one woven fabric layer, each woven fabric layer containing tape elements having a base layer of a strain oriented olefin polymer disposed between covering layers of a heat fusible olefin polymer. Each grouping of biaxially oriented thermoplastic films contain at least one biaxially oriented thermoplastic film which has a core layer of thermoplastic disposed between covering layers of a thermoplastic able to bond to polypropylene.

A multilayer tape assembly is described which can be used with insulation jacketing and particularly for self sealing lap (SSL) applications. The tape assembly includes two adhesive layers with associated carrier and release layers in conjunction with a differential release system. Various methods of use are also described.
