                         industry. However, a disadvantage is their susceptibility to 
                         interlaminar fracture because of poor adhesion at fiber surface 
                         and matrix interface. Carbon nanotube (CNT) growth onto carbon 
                         fiber (CF) surface is a promising method to increase CFmatrix 
                         adhesion. This work studies interlaminar properties of 
                         unidirectional CF composites and thermoset matrix, with CNT 
                         deposition on CF surface. CNT growth goes along in chemical vapor 
                         deposition with a floating catalyst of ferrocene and flow of CO2 
                         and C2H2 precursors. Tensile strength tests on single-filament and 
                         CF tow showed the preservation of tensile properties after 
                         preparation and growth. Results of the interlaminar shear strength 
                         study presented a 35% increase in shear strength and a 15% 
                         increase in fracture toughness at the initial delamination crack. 
                         An overall analysis reveals an improvement in the interlaminar 
                         interface on mechanical tests; however, fracture toughness 
                         analysis is limited by fragile pathways in intralaminar regions.",
