在压力下通过钎焊法使用电阻炉和真空热压炉均可制备出成形较好的Cf/Al复合材料。通过真空热压炉制备出的Cf/Al复合材料

其Cf的间距约为2

μm

钎料可以充分地填充到Cf间隙中

且Cf轮廓完整并较均匀致密地分布在结合层中。

Abstract

The carbon fiber reinforced aluminum matrix（Cf/Al）composite was successfully prepared by the brazing method through the box type resistance furnace and the vacuum hot pressing furnace. The influence of the composition of the filler metal

the pressure state and the pressure method on the forming of the Cf/Al composite was studied

and the microstructure of the composites was analyzed. The results show that the good Cf/Al composites can be prepared by using the resistance furnace and the vacuum hot pressing furnace with the laminated HL402 filler metal and heated to 600 ℃ for 15 min under pressure. The Cf/Al composite prepared by a vacuum hot pressing furnace has a distance of Cf about 2

μm

and the solder can be fully filled into the gap of Cf

and the contour of the Cf is complete and is more uniform and compact in the binding layer.
