Sheet material

Abstract

PURPOSE: To improve the tensile or tear strength as a sheet material by sticking a thin resin sheet on one face of a resin foam sheet foamed with synthetic resin. CONSTITUTION: A reinforcing sheet 2 made of a resin or nonwoven fabric sheet and formed thinner than a substrate 1 is laminated at least on one of the surface and back face of the substrate 1 formed with a resin foam sheet foamed at the preset expansion ratio to form a sheet material A by thermal fusion. The sheet material A formed into a two-layer structure is laid on a floor backing, and a laid floor is mounted on it. The tensile or tear strength required for constructing the laid floor can be secured. COPYRIGHT: (C)1992,JPO&Japio
