The present work tries to apply the recursion analysis technique to boron fiber reinforced aluminum matrix composites. Several sizes of comopsites (V_f : 0.10∿0.15) prepared by hot-press were used as the test materials. The tensile strengths of filament and composite specimen were measured several times. On the other hand, Weibull parameters of the strength of fibers were estimated from the measured data, from which recursive distribution curves were predicted. The results showed that the strength of composites gradually decreased with increasing the size of composites. The recursive curves indicated appropriately such a tendency, i.e. agreed well with the Weibull plots of experimental data. This means the recursion analysis technique can be applied to the evaluation of strength distribution of boron fiber reinforced aluminum matrix composites in a laboratory scale. In addition, the effect of 2-parameter and bi-modal Weibull distribution on the recursive solusion was discussed.
