The toughness mechanism of the liquid crystalline epoxy resin DGE(C2-MS-C2))-which has an α-methylstilbene moiety as a mesogenic group and ethylene oxy units as spacers-cured with diaminodiphenylethane (DDEt) was investigated using time-resolved wide-angle X-ray diffraction (WAXD) measurements perfo...
