Influences of burning temperatures on alumina fiber reinforced andalusite composites;

The results indicate that the alumina fibers is uniform in distribution and can serve as the sites for heterogeneous nucleation of silicon phase,and that the interfaces between the fibers and the aluminum alloy matrix have a great effect on the mechanical properties of the composites.

In this paper,the features of the new generation of continuous high-strength alumina fiber rein- forced aluminum composites,and their value and potential for applications are discussed in the respects of its fabrica- tion,performanee and application.

(Al2O3f+Cf)composites were fabricated by squeezing casting, the appearance of carbon fiber and Al2O3 fiber before-and-after pretreatment were investigated by scanning electron microscope.
