Title:
面材強化発泡体
Document Type and Number:
Japanese Patent JP5840616
Kind Code:
B2
Abstract:
A surface material strengthening foam and a molded body that are light and have excellent moldability, particularly deep drawing moldability, and wherein the obtained molded body has excellent dimensional stability, are provided. The surface material strengthening foam has a strengthened surface material, comprising glass fiber nonwoven fabric and thermoplastic resin, laminated to both surfaces of a strand foam from a non-crosslinking resin with a foam expansion ratio of 10-40 times by a continuous strand extrusion method. The surface material strengthening foam is characterized by: the tensile elastic modulus of the glass fiber nonwoven fabric being 0.7-1.2 kgf/mm2; the average fiber length of the glass fibers that comprise the glass fiber nonwoven material being 15-100 mm; the glass fiber content of the strengthened surface material being 25%-40% by mass; and the tensile elastic modulus of the strengthened surface material being 0.8-2.0 kgf/mm2.
