Study on Interfacial Properties of Carbon Nanotube Modified Epoxy Resin/T1000 Carbon Fiber Composites

Abstract This study was made on domestic T1000 carbon fiber to investigate its surface condition, precursor, multifilament, fiber/resin contact angle, interfacial shear strength and interlaminar strength. Analysis carried out examine the physical state of fiber, micro-scale properties mechanical composites. The results show that grade has no inherent characteristic defects such as visible bumps, rough edges or grooves surface. It can obtain higher tensile test shows carboxylated nanotubes are well dispersed in epoxy resin matrix by method. mixed good wettability fibers angle composite interface decreases. SYT65 fibers/resin increases 10.6%, 15.7%. Toray 6.1%, 14.1%. Compared with T1000, system used this is more compatible which give full play fiber.
