| Abstract: | The technology of fabricating high volume fraction particle preform and it's effect on the quality of their composites is investigated. Preforms with homogeneous distribution of large and small particles are made by ultrasonic dispersing technology.The maximum volume fractions are 53% and 66% respectively for single sized and muti sized particle preforms. Sound SiC p/Al composites with good macrostructure and microstructure can be obtained by improving press infiltration technology. |
