適応させやすい利点がある。In the disaster prevention sheet of the present invention, a sheet made of a woven PAN-based carbon fiber cloth is used as a base, and a silicone rubber coating layer having both flame retardancy and waterproofness is provided on one or both sides of the sheet. Therefore, it has high flame retardancy and exhibits excellent disaster prevention performance. Moreover, since the entire thickness can be reduced and the flexibility is excellent, there is an advantage that it can be easily applied to the disaster prevention object.
