摘要: A fibre coating process has been used to produce continuously reinforced advanced metal-matrix composites with up 8% volume fraction of SiC fibre. Matrix materials were an α/β titanium alloy (Ti-Al-V), a dispersion-strengthened (Ti-Al-V-Y), rapid solidification processed aluminium (Al-4.3Cr-0.3Fe), and intermetallic compounds Ti3Al TiAl. Thick metal coatings are shown adhere well the fibres, no evidence is found for chemical reaction between during process, coated fibres can be handled bent without damage. Tensile test data Ti-Al-V 21% show modulus near theoretical prediction, but tensile strength significantly below prediction. Loss attributed formation brittle product hot consolidation. The advantages potential coated-fibre route MMC production discussed.
