Abstract: A thermoplastic resin foam including a thermoplastic resin, wherein: the thermoplastic resin includes a polyester resin and a polyimide resin, and the thermoplastic resin foam shows a single glass transition temperature Tg. The glass transition temperature of the thermoplastic resin is preferably 80 to 130° C. An absolute value of difference between heat absorption and heat generation, each determined by heat flux differential scanning calorimetry at a heating rate of 10° C./min, is preferably 3 to 35 J/g.

Abstract: An object of the present invention is to provide a resin composition that can produce a foam molded body having a beautiful appearance while exhibiting excellent mechanical properties. The above object is achieved by a resin composition for producing foam particles, the resin composition comprising a base resin containing a polycarbonate resin having a glass transition temperature of 140 to 155° C. and an amorphous polyester resin having a glass transition temperature of 100 to 130° C., and the amorphous polyester containing a unit derived from a cyclic diol.

Abstract: A resin composite having excellent strength is easily produced by using a resin foam having a specific surface roughness (Ra) as the core material of the resin composite.

Abstract: The resin composite of the present invention has a polyamide-based resin expanded sheet, and a fiber-reinforced resin layer integrally laminated on a surface of the polyamide-based resin expanded sheet.

Abstract: Expanded particles including a base resin including a copolymer of an aromatic vinyl compound, a (meth)acrylic acid ester, and an unsaturated dicarboxylic acid, in which the expanded particles have an average cell diameter of 5 to 50 ?m and a standard deviation of the average cell diameter of less than 0.8.

Abstract: A resin composite in which a fiber-reinforced resin material comprising fibers and a resin, and a resin expanded body are integrally laminated, wherein the resin expanded body has a hole opened at the interface with the fiber-reinforced resin material and resin of the fiber-reinforced resin material is caused to flow into the hole.
