Al 12Si, Al 12Si Cu and Al 12Si Mg matrix composites reinforced with δ Al 2O 3 short fibres were fabricated by using squeeze casting. The three composites' room temperature tensile strengths were analyzed by linear regression method(LRM). Their prediction equations for φ min , φ c and σ′ m were worked out accurately. The relationship between σ′ m and σ um was discussed in detail. The results showed that the reinforcing effect of composite decreases with increasing σ′ m , and σ′ m and σ′ m σ um increase with increasing matrix strength so that the higher the strength of the matrix is, the lower the reinforcing effect of composite is.
