Influence of Electroless Nickel-plating on Fracture Toughness of Pitch-based Carbon Fibers-reinforced Composites |
| 초록 |
Pitch-based carbon fibers (PFs) were electrolessly nickel (Ni)-plated chemically to enhance the fracture toughness of the Ni-PFs-reinforced epoxy matrix composites. The surface properties of the Ni-plated PF (Ni-PFs) were determined by scanning electron microscopy (SEM), X-ray photoelectron spectrometry (XPS), X-ray diffraction (XRD), and contact angle measurements. The fracture toughness of Ni-PFs-reinforced composites (Ni-PFs/epoxy) was assessed by critical stress intensity factor (KIC) and critical strain energy release rate (GIC). The fracture toughness of Ni-PFs/epoxy was enhanced compared to those of PFs/epoxy. These results were attributed to the increase of the degree of adhesion at interfaces between PFs and matrix resins in the composite due to electroless nickel plating. |
