| Abstract: | The bonding strength between alumina short fiber reinforced aluminum alloy and matrix was determined and the physical meaning of the bonding strength was also discussed.The physical meaning of the bonding strength is the weighted average of the interface's tensile strength and the stress in matrix when the sample reach fracture strain corresponding to the fraction of fiber volume and the fraction of matrix volume respectively. According to the bonding strength determined we kown some kinds of interface tensile strength by finite element analysis. |
