摘要

The main preparation methods of ultra-long pores are carried out by mechanical or special processing over a long time, and by the casting method the aspect ratio of pores is smaller than 2. In the present article, according to weak wettability between carbon fiber and aluminum, carbon fiber was chosen as the pore-forming material then ultra-long pores were fabricated successfully by means of pulling-casting. The experimental result demonstrated that the pore aspect ratio was 495, and pore diameter was about 0.222mm. Theoretical analysis shows that the effect of surface tension on invalid pore length can be neglected - this value was only 0.01mm. X-ray diffraction results showed that there was almost no chemical reaction between aluminum and carbon fiber bundles, which means that undamaged carbon fiber was beneficial for pulling. Otherwise, because the carbon fiber was in a loose state previously and there were differences between actual measurement diameter and theory diameter after pore formation, loose carbon fiber bundles were easily pulled and it was helpful to realize ultra-long pore preparation.
