The poor mechanical properties of akermanite (AKM), especially fracture toughness, limits its appliions in bone tissue engineering, although it possesses favorable biological performance. In this research, silicon carbide whiskers (SiCw) are added in order to
CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract — In this paper, an approach to find the effect of carbon nanotubes addition on fracture toughness in aluminium silicon carbide composite is been analyzed. Although properties
The YSZ-SiC composites also exhibited high flexural strength (as high as 1142 MPa) and high fracture toughness (up to approximately 8 MPa-m 1/2), which are similar to those of the fine-grained YSZ. Such a coination of mechanical properties was attributed to the fine microstructure with a distinct feature consisting of almost continuous network of YSZ phase around SiC particles.
