Abstract:

The slurry was prepared with 13*m and sodium alginate solution, then a yarn of SiC fiber was impregnated into the slurry. The precursory tape of SiC/Al was then obtained and hot-pressed. The longitudinal strength of SiC/Al composite with a fiber fraction of 18% was 376MPa.If the temperature and/or pressure were too high, the strength of fiber and composite will be degraded because of the damage of fibres.

Key words: composite, slurry method, hot-pressing
