Abstract: Provided is a thermoplastic resin structure formed of a resin composition that comprises substantially (a) from 5 to 80% by volume of a polyamide resin and (b) from 20 to 95% by volume of a polyphenylene sulfide resin, which is characterized in that, in morphology therein seen through electronic microscopy, the polyphenylene sulfide resin (b) forms a matrix phase (continuous phase) and the polyamide resin (a) forms a disperse phase. The gives plastic containers, tubes and their Attached parts having good barrier properties, strength, durability and workability.

Abstract: The present invention provides a prepreg having an excellent self adhesiveness to a honeycomb core, a low porosity when used as skin panels, an excellent surface smoothness due to a low surface porosity, and good tackiness and drapability. This invention also provides a honeycomb sandwich panel having a skin panel peel strength, an excellent impact resistance and an excellent hot water resistance, and a composition for a fiber reinforced composite material made from the prepreg and honeycomb sandwich panel. The fiber reinforced composite material made from the prepreg of the present invention can be used for airplanes, automobiles and other industrial applications, particularly as structural materials of airplanes, because of its excellent mechanical properties.
