PROBLEM TO BE SOLVED: To provide a sandwich panel, in a relatively low cost, which is easy to be processed at a manufacturing time and which exhibits an excellent mechanical strength after being manufactured.SOLUTION: A door panel 1 includes: a tabular core body 3; a pair of face plates 2A, 2B respectively disposed overlappingly on a pair of faces of the core body 3; and a reinforcing member 4 formed by hardening an adhesive agent 10 provided so as to bond the core body 3 and the face plates 2A, 2B, and the strength after the hardening is stronger than that of the core body 3. The core body 3 is provided with groove parts 3A, 3B respectively formed on its pair of faces. The groove parts 3A, 3B cross each other and communicate in a communication passages 3C. The reinforcing member 4 is provided with ribs 4A, 4B formed by hardening the adhesive agent 10 filled inside the groove parts 3A, 3B.
【課題】製造時には加工し易く、完成時には良好な機械的強度を発揮することが可能なサンドイッチパネルを比較的低コストで提供する。【解決手段】ドアパネル1を、板状の芯体3と、芯体3における一対の面にそれぞれ重ねて配された一対の面板2A、2Bと、芯体3と面板2A、2Bとを接着するように配された接着剤10を硬化してなり、硬化後の強度が芯体3の強度よりも高い補強部材4とを用いて構成する。芯体3は一対の面のそれぞれに形成された溝部3A、3Bを有する。溝部3A、3Bは互いに交差し、連通路3Cにおいて連通する。補強部材4は、溝部3A、3Bの内部に充填した接着剤10を硬化して形成したリブ4A、4Bを有する。【選択図】図2
