<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a low density resin laminated sheet that enables further low specific gravity without spoiling other characteristics such as the appearance, electrical characteristics, mechanical strength, and thermal conductivity. <P>SOLUTION: A method for manufacturing the low density resin laminated sheet in that the thermosetting resin powder has putting on temporary to the reinforcement material made of the fiber particle size 20-40 μm, includes: (i) a step of forming the powder composition by uniformly mixing (a) thermosetting resin powders (b) organic balloons, inorganic balloons, and the filler selected from a group comprising those mixtures; (ii) a step of making the powder composition uniformly contact the surface of the reinforcement material made of the fiber; (iii) a step of heating the powder composition under pressurization and perform tack welding of the fiber made reinforcement material to make the sheet-like material; and (iv) a step of performing fusion integration by laminating, heating and pressing a plurality of sheets. <P>COPYRIGHT: (C)2013,JPO&INPIT |
