PURPOSE:To provide a foamed structure, which is tough against external stress and excellent in the prevention of the permeation of water, a surface of which is colored and which can print a character, a figure, a pattern, etc., finely and distinctly and can display a fine appearance grade. CONSTITUTION:A resin layer mainly formed of the polysulfide modified epoxy resin of both terminal epoxy groups having a bisphenol skeleton and a polysulfide skeleton and amines or polyamino-amides is used as an outermost layer, a composite layer consisting of fibers and a resin is employed as an intermediate layer, and the composite layer is formed from structure in which one part of conjugate fibers and/or composite thread is plasticized and the other section substantially has a fibrous type in at least a partial surface layer, and the composite layer and a foam are unified and constituted, thus manufacturing a foamed structure. |
