Abstract: A composite comprising a core, a first cover layer and a second cover layer, wherein the core is provided from an uncut flat body, wherein the core is a three dimensional structure having a first main surface and a second main surface, the first cover layer is in contact with the first main surface creating multiple contact areas and the second cover layer is in contact with the second main surface creating multiple contact areas, wherein the multiple contact areas between the first cover layer and the first main surface are offset in x-direction and y-direction to the multiple contact areas between the second cover layer and the second main surface, characterized in that the first cover layer and the second cover layer are different.

Abstract: A ballistic-resistant article includes a stack of sheets containing reinforcing linear tension members, the direction of the linear tension members within the stack being no unidirectionally, wherein some of the linear tension members are linear tension members comprising high molecular weight polyethylene and some of the linear tension members comprise aramid. A sheet and a consolidated sheet package contain the ballistic-resistant article, and a method of manufacturing produces the ballistic-resistant article.

Abstract: A ballistic-resistant moulded article containing a compressed stack of sheets that contain high molecular weight polyethylene tapes. The direction of the polyethylene tapes within the compressed stack is not unidirectional. At least part of the tapes have a width of at least 2 mm, a thickness to width ratio of at least 10:1, and a density of at most 99% of the theoretical tape density. The moulded article is made of tapes that have a density below the theoretical density of the tapes.

Abstract: A rope includes elongate bodies having a length axis parallel to a length of the rope or showing helix angles smaller than 2°. The elongate bodies include tapes of ultra-high molecular weight polyethylene. The tapes have a width to thickness ratio of at least 10 and a polymer solvent content below 0.05 wt. %.

Abstract: A ballistic-resistant molded article comprising a compressed stack of sheets comprising reinforcing elongate bodies and an organic matrix material, the direction of the elongate bodies within the compressed stack being not unidirectionally, wherein the elongate bodies are tapes with a width of at least 2 mm and a thickness to width ratio of at least 10:1 with the stack comprising 0.2-8 wt. % of an organic matrix material.

Abstract: The invention discloses a process for refining yarn or sliver having a length of at least 1 meter, including the step of feeding the yarn or sliver and a liquid into a refiner, which includes refiner fillings having a body surrounding a central hole (7), and at least one inlet (1) for the yarn or sliver, and the thus obtained pulp-like materials and its use for making friction materials, paper, and gaskets. In particular, the refiner has a refiner filling (8), wherein the yarn or sliver is fed through an inlet positioned in the refiner filling. The present invention further relates to the refiner filling including at least one, preferably eccentric, inlet for yarn or sliver. The inlet comprises an inlet hole which includes an inclined slope (2) on the outflow side of the inlet, the inclined slope serving to guide the yarn or sliver from the inlet hole to the surface of the refiner filling. The invention further relates to a refiner including such refiner filling.

Abstract: A refined fiber having an average length of 2 to 4 millimeter, a filler retention value of at least 18%, and a green strength value of at least 1.8 mJ/mm2 is described. The fiber is obtainable by a process wherein never dried yarn or sliver having a length of at least 1 meter is refined, by at least the step of feeding the yarn or sliver and a liquid into a refiner, which includes refiner fillings having a body surrounding a central hole, and at least one inlet for the yarn or sliver. Thus obtained fibrillated fiber may be used for making friction materials, gaskets, brake pads, or brake linings.
