Fabrication of Carbon Fiber Reinforced Magnesium-Based Composite Laminates by Vibration Assisting Hot Pressing

Abstract:

Carbon fibers reinforced AZ31 composite laminates were fabricated by vibration aided mechanical hot pressing. Optical microscopy (OM), scanning electron microscopy (SEM) and X-ray diffraction (XRD) were used to analyze their phase components and microstructure. The interfacial bonding strength was measured by uniaxial tension testing. The results showed that Mg-Zn-Al eutectic alloy solder had a strong bonding with carbon fibers and a noticeable diffusion with AZ31 alloy. No debonding was observed on the interface of carbon fibers, and no carbide was detected in this system. The bonding strength of composite laminate reached up to ~17.48MPa which was close to the bonding strength of AZ31/Al composite laminate. It was indicated that vibration assisting hot pressing was a feasible technique for the fabrication of Mg-based composite laminates reinforced with uncoated carbon fibers.
