Effects of Thickness Ratio on Interface Characteristic and Mechanical Properties of Ti/C Laminated Composites

Abstract:

The Ti/TiC/C laminated composite material was fabricated with the sheet of Ti and C by spark plasma sintering (SPS) technology. The effects of thickness ratio on the interface characteristics and mechanical properties of interfacial reaction were studied. The results show that: the reaction layer thickness increases with the thickness ratio. When the thickness ratio was 3:1, the degree of interfacial reaction was better in the case of other conditions are the same. The thickness of reaction layer achieved 33.58μm. The laminated composite bending strength and fracture power reached the maximum 3494.52MPa and 614.89×103J/m2, respectively. The greater fracture power, the more energy absorbed in the process of damage, the higher toughness improved.
