    • The present invention relates to a method for molding a high thermal resistant sound-absorbing substance which is mounted on an engine cylinder block of a vehicle and an upper vehicle body panel of a muffler by using sound-absorbing material consisting of 20-80 parts by weight of fiber materials with a limited oxygen index (LOI) of 25% or more and a thermal resistant temperature of 200°C or greater and 20-80 parts by weight of thermosetting resins with a thermal resistant temperature of 200°C or greater and, more specifically, to a method for molding a high thermal resistant sound-absorbing substance comprising: a release agent spraying step of spraying a releasing agent to the inner space of a hot-working mold; a hot-working compressed molding step of fixing a shape; and a cool-working compressing step of stabilizing the shape. The high thermal resistant sound-absorbing substance molded by the method is able to reduce the interior noise of a vehicle by preventing a radiated noise generated from an engine and exhaust system from being transferred to the inside of the vehicle through a vehicle body panel; is able to maintain a shape even in the hot environments of 200°C or greater generated in the engine and the exhaust system; and is able to satisfy the flame retardant of UL 94V-0.

    • The present invention relates to a high temperature resistant sound absorbing material for a vehicle, and more particularly, to a high temperature resistant sound absorbing material for a vehicle, which is made of a fiber material whose limit oxygen index (LOI) and heat-resistant temperature are above 25% and 200°C respectively and a thermosetting binder resin whose heat-resistant temperature is above 200°C. The fiber material and the thermosetting binder resin are mixed at a constant ratio. Therefore, the shape of the high temperature resistant sound absorbing material for a vehicle is not changed and the material satisfies the flame retardancy of UL 94V-0. The high temperature resistant sound absorbing material of the present invention is installed in the area nearest the noise sources of an engine and an exhaust system and significantly reduces the radiating noise of the engine and the radiating noise of the exhaust system, thereby improving the quietness inside a vehicle. Also, the high temperature resistant sound absorbing material of the present invention is applied around metal parts above 200°C, thereby demonstrating insulating functions to protect plastic and rubber parts around the metal parts.
