摘要：

The interfacial interaction between carbon fibers (CFs) and resin matrix is an important factor affecting mechanical performances of CF-based composites. In this work, a new approach combining electrodeposition method (EDM) and "Ag-S" bonds was applied to fabricate functional CF-based composites while preserving the mechanical properties of CFs. Silver nanoparticles were first attached on the CF surface by EDM. Then 4-aminothiophenol or 4-mercaptobenzoic acid was linked to Ag surface by Ag-S bonds to incorporate different functional groups onto the fiber surface. The interfacial shear strength was improved pronouncedly while the tensile strength was maintained consistent. The interfacial shear strength of the CFs after functionalized was increased 21.10% and 32.04%, respectively. However, the tensile strength of them decreased no more than 3%. With improved properties, these nanocomposites have potential applications for aerospace, transportation, electronics and other fields.
