| Abstract: | The tensile strength of squeeze casting ZA22/Al 2O 3 short fiber composite was measured with autograph AG 10TA universal testing machines made in Japan. The experimental results were analysed with the rule of mixture(ROM) model modified by Friend. The theoretical analysis agree well with the experimental results. Under the test condition of this study, the strengthening critical fiber volume fraction predicted is 34 5%. Because fiber volume fraction in the composite is under this value, the tensile strength of the composite is lower than that of ZA22 alloy matrix. |
