Abstract

PURPOSE:To improve sound absorbing and heat insulating properties and increase mechanism strength, by a method wherein a glass fiber mat and a hard urethane foam are formed integrally by heat while spraying thermosetting resin. CONSTITUTION:A soft urethane foam sheet 2 is superposed on both or one surface of a glass fiber mat 1, whose glass wool bound by spraying uncured thermosetting resin, then, they are heated and pressed to form them integrally. According to this method, the soft urethane foam 2 soaks into the glass fiber mat 1 and adhered rigidly and respectively to glass fibers through so-called anchoring effect whereby the mechanical strength of the end of the formed form is improved and it becomes hard to break. A sound absorbing heat insulator, excellent in heat insulating and sound absorbing properties as well as rigidity and mechanical strength in spite of the complicated configuration, can be obtained.
