摘要： In a resin sandwich panel, the two resin skin material sheets have peripheral edge portions thereof joined to each other so as to form an internal hollow portion. The resin core material is disposed in the hollow portion. At least one of surfaces of the resin core material opposing the two resin skin material sheets has a groove portion extending across the entire surface, and a depression communicating with the groove portion. At least one of the two resin skin material sheets additionally has an atmosphere-opened through-hole provided in a thickness direction thereof. When the one of the surfaces of the resin core material and the corresponding resin skin material sheet are surface-to-surface adhered to each other in the hollow portion, air between the surfaces and the skin material sheet is guided to the depression via the groove portion, and exhausted out of the atmosphere-opened through-hole.

摘要： Provided is a resin-laminated board that can improve the stiffness further while securing the weight and thickness reduction. A resin-laminated board includes a front-side sheet 120A and a backside sheet 120B layered on each other with a hollow part interposed therebetween. The backside sheet 120B is recessed toward the hollow part to provide a plurality of first recesses 200S and a plurality of second recesses 200L. The front-side sheet 120A and the backside sheet 120B are connected to each other with plural ribs by welding bottoms of the first recesses 200S and the second recesses 200L to the front-side sheet 120A. The resin-laminated board has a thin-plate part 100a having the first recesses 200S with small depth and a thick-plate part 100b having the second recesses 200L with large depth, and the first recesses 200S and the second recesses 200L are arranged at substantially the same pitch.
