    摘要: Disclosed are a holey plate, which improves the shape of punched holes so as to increase sound absorbing and insulating efficiency and durability, and a composite panel for sound absorption and sound insulation using the same. The holey plate used in the composite panel includes a base part, first bent parts configured to be bent from designated regions of the base part and to extend to be inclined so as to form a plurality of first punched holes by punching the designated regions of the base part in a thickness direction, and second bent parts configured to be bent from the first bent parts and to extend to be inclined so as to form second punched holes extending from the first punched holes, an angle of the second bent parts with the base part being smaller than an angle of the first bent parts with the base part.

    摘要: Disclosed herein is a composite panel for sound absorption that may absorb and block noise. The composite panel may include: a first perforated panel comprising first embosses and first perforation groups formed in a predetermined pattern, wherein the first embosses are formed by forming a plurality of cells and the first perforation groups are formed by collecting a plurality of first perforated holes; an embossed panel comprising second embosses formed by forming the plurality of cells and coupled to the first perforated panel wherein the embossed panel is laminated with the first perforated panel; and a sound absorbing and insulating material inserted between the first perforated panel and the embossed panel.

    摘要: Disclosed is an insulation fiber composite. In particular, a surface of the insulation fiber composite is substantially improved such that a shape of three dimensions can be maintained as a heat resisting fiber and an insulation material are integrated. The insulation fiber composite of the present invention has excellent formability and surface property and comprises an insulation layer; and a pair of inorganic fiber layers. A first inorganic fiber layer of the pair is stacked on an upper surface of the insulation layer and a second inorganic fiber layer is stacked on a lower surface of the insulation layer, respectively. In particular, each the inorganic fiber layers has a greater planar surface area than a planar surface area of the insulation layer such that the insulation is not exposed to an exterior when the insulation layer and the pair of the inorganic fiber layers are stacked.
