Abstract: The invention relates, in a first aspect, to a flat semi-finished product made of metal (1), wherein said semi-finished product comprises at least out structured section (2) and at least one non-structured section, wherein said semi-finished product has non-structured edge sections (4) and exhibits a high strength. The semi-finished product made of metal (1) according to the invention is characterized in that it is designed as one piece and predetermined sections (2) are structured and predetermined sections are non-structured, wherein at least one non-structured section (4) is designed as a connecting region for positive or non-positive connection or for connecting by bonding. Furthermore, methods for producing the semi-finished products according to the invention are provided.

Abstract: Continuous fiber molded part for silencers or mufflers comprising a continuous fiber and a coat of inorganic binder, wherein the coat encloses the continuous fiber.

Abstract: Balls changing volume when activated efficiently filing a gap providing acoustic and thermal insulation. A method of manufacturing of means for acoustic and thermal insulation, particularly at high temperatures, comprising providing an insulating and damping material; shaping of the insulating and damping material having geometric shapes, such as spherical or elliptical shapes, by a shaping processes, such as forming into a ball and/or foaming up.

Abstract: A muffler insert for motor vehicles, in particular for passenger cars and motor trucks, in the form of a shaped material made from glass fiber material, has a wound continuous glass fiber material which includes a textured glass fiber. When producing the muffler insert the glass fiber material is wound around a carrier in order to form a shaped material, and this shaped material is used as a muffler insert, if appropriate after further processing steps.

Abstract: A first aspect of the present application relates to a method for producing sound-damping, sound-absorbing and/or insulating molded material. More specifically, the method according to the invention relates to a method for producing said molded materials, wherein the fibrous material is wound around at least two carriers and subsequently the wound blank thus obtained remains on the carriers so as to be permanently solidified in order to obtain the molded material according to the invention. A further aspect of the present application concerns the molded material thus obtained, in particular in the form of molded mats or molded objects. Said molded material can be used, in particular, in mufflers. Finally, the following application concerns a device for producing said molded materials from fibrous material.
