    摘要: An object of the present invention is to provide a sandwich panel which is capable of securing its flexural or its shear rigidity as a whole and securing a compression rigidity of a core material itself, while at the same time of readily reducing the weight of the sandwich panel.According to an aspect of the invention, there is provided a sandwich panel comprising two resin skin sheets, and a resin core material sandwiched between the two resin skin sheets and planarly adhered to each of the two resin skin sheets, said core material consists of an foamed resin with a predetermined expanding ratio and has a plurality of recesses each of which forms an opening formed on at least one surface thereof and extends inwardly to define an inner space closed by the corresponding skin sheet, the number of said recesses and the total area of the openings are determined in such a manner that the planer adhesion of at least one surface of the resin core material to the corresponding skin sheet is maintained, while at the same time solid portions of the foamed resin of the resin core material excluding said inner space formed by the plurality of recesses function to support a compressive load in the thickness direction of the resin core material, under the predetermined void volume allocated to said plurality of recesses in relation with said predetermined expanding ratio.

    摘要: An object of the present invention is to provide a method for forming a resin molded article, a resin molded article forming apparatus, and an apparatus for adjusting a thickness of a thermoplastic resin sheet which are capable of preventing a draw-down or a neck-in phenomenon of a molten sheet-shaped thermoplastic resin extruded downwardly in a suspended manner without putting a restriction on the type of resin to be adopted. There is provided a method for forming a resin molded article characterized by comprising the steps of melting and kneading a thermoplastic resin, storing a predetermined amount of the melted and kneaded thermoplastic resin, extruding the stored thermoplastic resin intermittently in a predetermined extrusion amount per unit time from an extrusion slit provided in a T-die and having a predetermined gap, such that the resin droops downward in a shape of a molten sheet, whereby the molten sheet-shaped resin having a predetermined thickness is extruded downwardly from the extrusion slit at a predetermined extrusion speed, and sandwiching the sheet-shaped resin between a pair of rollers arranged below the extrusion slit and feeding the resin downward at a feeding speed higher than, or equal to the predetermined extrusion speed by rotary driving of the rollers, in such a manner that the pair of rollers is relatively moved toward each other after a lowermost part of the sheet-shaped molten resin extruded downward passes through between the pair of rollers whose gap is widened to be larger than the predetermined thickness of the sheet-shaped resin, disposing the sheet-shaped molten resin, fed by the rollers, near a side of a mold arranged below the pair of rollers, and forming the sheet-shaped resin in a shape conforming to a shape of the mold by depressurizing a sealed space formed between the sheet-shaped resin and the mold and/or pressurizing the sheet-shaped resin toward the mold.
