PURPOSE: A gasket unit and a high-temperature gasket assembled out of gasket units are provided to prevent oxidation or instantaneous explosion due to the infiltration of exterior air. CONSTITUTION: A gasket unit comprises a heat-resistant nonwoven fabric group(100), a first silicon resin(200), ceramic fiber, and a second silicon resin(400). The heat-resistant nonwoven fabric group comprises a first heat-resistant nonwoven fabric group(110) formed by laminating a plurality of heat-resistant fabrics(130) cut at regular intervals and a second heat-resistant nonwoven fabric group(120) arranged at a predetermined interval from the end of the first heat-resistant fabric group at the top of the first heat-resistant fabric group. The first and second heat-resistant nonwoven fabric groups are attached by the first silicon resin. The ceramic fiber covers the exterior of the heat-resistant nonwoven fabric group and the surface of the ceramic fiber contacting the heat-resistant nonwoven fabric group is attached by the first silicon resin. The outer surface of the ceramic fiber is coated with the second silicon resin, which has the same composition as the first silicon resin. |
