Preparation carbon nanotube-decorated carbon fibers under low pressure for epoxy-based unidirectional hierarchical composites with enhanced interlaminar shear strength

Multi-walled carbon nanotubes (CNTs) were grown in-situ on the surface of carbon fibers (CFs) at low pressure by a vertical chemical vapor deposition (CVD) reactor. The surface of CFs was modified by electrochemical anodization, and the growth morphology and other properties of CNTs were analyzed by...

The CNT-grown CF reinforced unidirectional hierarchical composite material based on the epoxy resin was prepared. The interlaminar shear strength (ILSS) indicates that the maximum strength of the composites reaches 108 MPa after the CNTs are grown on the CF surface with a 25.2% increase than that of the desized CF composites.
