| Abstract: |
| The SiCp/Al composites with volume fraction 70.28% were fabricated by compression molding,750℃ Microwave Sintering and Vacuum Pressure Infiltration with W10 and W63 two kinds of SiC powder,6063 Al Alloy and high temperature adhesive combined with low temperature adhesive.The results show that there are no obvious Al4C3 interphase and impurity phase like SiO2 in the XRD pattern of the composites with high relative density and its Thermal Expansion Coefficient is 7.239×10-6K-1 at 100℃,the Thermal Conductivity is 160.42/W(m·K)-1 at normal temperature,the maximum bending load of the sample with the size of 4mm×3mm×30mm is 282N and the bending displacement is about 0.29mm.The SiCp/Al composites prepared with such excellent overall properties is good electronic packaging Material. |
