When honeycomb core sandwich panel (hereafter, HSP for brevity) is used as a floor panel, a dent will be formed on the face sheet of the HSP. If the high toughness material such as Carbon fiber reinforced plastics (hereafter, CFRP for brevity) is used as the face sheet, it is thought that the period for use as the floor panel will extend. In this study, a static local compression test and a local compression fatigue test was carried out on the HSP with the laminated the CFRP face sheets. From the static local compression test, it was found that the CFRP laminate broke depending on the bending stress. From the local compression fatigue test, the fatigue life was longer with the interface the number of laminated sheets when. It was confirmed that the fatigue life was prolonged when CFRP in the 45 ° direction was incorporated in the laminated structure. The core similarly collapsed of all HSPs during the fatigue. And no cracks occurred in the CFRP laminate.
