Monothetic SiC,Cu,and SiC/ Cu laminated composites with different SiC layer thickness were synthesized by magnetron sputtering. The microstructure of the SiC/ Cu laminated composites were characterized by SEM and XRD. In dentation test and tensile experiment were carried out on micro鄄hardmeter and electronic universal testing machine(IN STRON),respectively. The experimental results show that clear interfaces are formed in SiC/ Cu laminated composites. Com pared with monothetic SiC,the toughness and tensile strength of SiC/ Cu laminated composites can be improved,however,the
hardness decreases. From the examination of fracture surface reveales that crack deflection,bridging,plastic deformation of Cu ductile metal layers are main reasons to improve the tensile strength of SiC/ Cu laminated composites.
