Title:
SURFACE SHEET, SANDWICH STRUCTURE AND ARTICLES USING THEM
Document Type and Number:
WIPO Patent Application WO2001009404
Kind Code:
A3
Abstract:
The present invention relates to a structural surface sheet consisting of the first surface member of stainless steel and the second surface member consisting of fiber-reinforced polymer composite material having the thermal expansion coefficient similar to that of the stainless steel of the first surface member and also having mechanical characteristics similar to those of a metal in order to exhibit excellent debonding resistance so that the first surface member assumes the function of preserving inherent surface characteristics as the gracefulness, prolonged life, anti-corrosion and anti-erosion while the second surface member assumes the structural function including the reduction of weight. The present invention also relates to a surface sheet comprising the same first surface member and the same second surface member as in the above to be used for a sandwich structure in conjunction with a core member and another surface sheet as well as the resulting sandwich structure. The present invention further relates to a product based on the above-described surface sheet or sandwich structure for use as railroad vehicles, containers, cabins, external decorative building materials, partitions and outdoor constructions.
