Abstract:Fabricating method of Al-Cu laminated composite strengthened by SiC particles has been introduced. The relation between bending strength, wear resistance of the composite and the content of SiC particles has been studied. The results showed that, when the amount of SiC particles is 20%, the comprehensive properties of the composite, the bending strength and the wear resistance are the best. The bending strength between SiC particles and the Al-Cu matrices and the interstratified stress affect apparently the properties of the composite.
Key words: SiC particles aluminium alloys laminated composite
