The relations between thermal expansion properties and temperatures in fiber directions 0, 45 and 90 degree as well as those of stacking sequence of layers and out-of-plane deformation in heating were obtained by employing heat-resistant markers as the optical targets of the EODT. The technique was also adapted in thermal expansion and tension tests of Titanium alloy (Ti-6 A1-4V) specimens at temperatures ranging from room temperature to 500C, and the results demonstrated the validity of the present technique., 資料番号: NALTR0810000, レポート番号: NAL TR-810}, title = {電子光学式変位計による航空機用耐熱材料の熱変形の測定}, year = {1984} }
