FIBER REINFORCED RESIN-MADE SANDWICH STRUCTURE AND MANUFACTURING METHOD OF FIBER REINFORCED RESIN-MADE SANDWICH STRUCTURE

PROBLEM TO BE SOLVED: To provide a fiber reinforced resin-made sandwich structure having enhanced manufacturing efficiency and recycling property, as well as enhanced connection force which is exerted on a part where a core material and a skin material are connected.SOLUTION: A fiber reinforced resin-made sandwich structure 1 has a core material 2, and one skin material 3 and the other skin material 4 each arranged on both surfaces of the core material 2. The core material 2 is a discontinuous fiber-reinforced thermoplastic resin composite material, and the one skin material 3 and the other skin material 4 are continuous fiber-reinforced thermoplastic resin composite material. Surfaces of the one skin material 3 and the core material 2 are connected each other, and the other skin material 4 and the core material 2 are connected at point-like or linear manner.SELECTED DRAWING: Figure 1 【課題】製造効率、リサイクル性、及び、芯材との表皮材とが接合されている部分の接合力を向上させた繊維強化樹脂製サンドイッチ構造体を提供する。【解決手段】繊維強化樹脂製サンドイッチ構造体１は、芯材２と、芯材２の両面に設けられた一方の表皮材３及び他方の表皮材４を有し、芯材２は不連続繊維強化熱可塑性樹脂複合材料であり、一方の表皮材３及び他方の表皮材４は連続繊維強化熱可塑性樹脂複合材料であり、一方の表皮材３及び芯材２は、面同士が接合されており、他方の表皮材４及び芯材２は、点又は線状に接合されている。【選択図】図１
