The Infiltrability of Zn-Al Semi-solid Slurries into Carbon Fiber Sheets During Hot Pressing

Infiltrationbehaviour of Zn-Al semi-solid slurries into carbon fibre (Cf) sheet during hot pressing was investigated. A parameter, termed Solid Fraction Increasing Rate (SFIR) vs. temperature drop, is proposed to evaluate the infiltrability of semi-solid slurry during hot pressing. The infiltrability of the slurry during hot pressing varies inversely with the value of its SFIR. The stronger infiltrability of Zn-8%Al slurry during hot pressing at 385 °C is attributed to its lower SFIR.
