摘要： A multi-layer sheet of the present invention comprises a thermoplastic resin foam sheet, a reinforcing sheet layered on integrated with at least one side of the thermoplastic resin foam sheet; the reinforcing sheet being formed by a non-woven fabric which comprises non-meltable fibers which are interwound with one another and which are bound together with a thermoplastic resin, the thermoplastic resin foam sheet having an aspect ratio Dz/Dxy of bubbles of 1.2 or more, and an expansion ratio of 5˜50 cc/g, and therefore the sheet is excellent in bending strength, compressive strength, thermo-forming property and dimensional stability as well as lightweight property, and so can ideally be used for an upholstery material for vehicles, a heat-insulation material, a buffer material and the like.

摘要： An object of the present invention is to provide a composite foam having a high compressive strength. A polyolefin resin is melted and kneaded with a modifying monomer to react them. A thermally decomposable chemical foaming agent is added to the obtained modified resin, and the mixture is kneaded. The obtained foamable resin composition is shaped into a sheet. A sheet-like facing material (3) having a strength sufficient to inhibit the foamable sheet from expanding in in-plane directions during thermal foaming is laminated on at least one side of the foamable sheet. The obtained foamable composite sheet is thermally foamed to produce a composite foam (1) having rugby-ball-shaped cells (2) oriented in the direction of the sheet thickness.
