TENSILE AND FLEXURALCHARACTERIZATIONAll specimens were manufactured usingultrasonication (functionalized and nonfunctionalizedXD-CNTs)Tensile tests were performed using ASTM D638standard.Flexural tests were performed using ASTM D790standard.Neat resin and resin with 0.015% and 0.15% byweight XD-CNTs concentration were used.
