    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 method of manufacturing a headlining, using a moisture-curing adhesive that can be molded at a relatively low temperature and enables energy saving by not requiring a condition in which bonding surfaces are preheated to an excessively high temperature. A headlining manufactured thereby the same method is also disclosed. The method includes coating a fabric with a moisture-curing adhesive, curing the moisture-curing adhesive by spraying water onto the moisture-curing adhesive, forming a headlining member by putting the fabric coated with the moisture-curing adhesive on a substrate after the curing, and pressing the headlining member so that the fabric and the substrate are bonded to each other and the headlining is shaped at the same time, after the forming.
