 note = {There is a concern that a thermal stress in a solar array panel under cryogenic environment would damage a solar cell and its interconnector, which might result in a drop of electrical power. Therefore it is important to perform the verification test on the ground to assure the healthiness of solar cells in orbit. In this study, we have developed the health monitoring method for solar array panel using Fiber Bragg Grating (FBG) sensor which is one of optical fiber sensors. In this paper, to reveal the thermal deformation behavior of the substrate composed of very thin Carbon Fiber Reinforced Plastics (CFRP) faceskin and aluminum honeycomb core in cryogenic environment, we measured the strain of CFRP faceskin near the center of honeycomb cell and showed that the depth of dimple increased linearly as temperature lowered. In addition, to confirm the effectiveness of our health monitoring method, we measured the internal strain of solar array panel and showed that we could detect its internal damage by strain change, and we observed the cross section of the damaged area and identified the damage point., 形態: 図版あり, Physical characteristics: Original contains illustrations, 資料番号: DS1540529002},
