influence of the pyrolytic carbon fibre coating on the strength of Textron SiC fibre in and aluminium matrix composite

摘要

For predicting the strength of fibre-reinforced metal matrix composites, the in-situ fibre strength value has to be introduced in the calculations. Tensile tests have been conducted on SiC fibres (SCS0 and SCS2 TEXTRON) before and after chemicalinteraction with a pure liquid aluminium bath. The reacted fibres have been tested before and after dissolution of aluminium coating on fibres. The results obtained for the different fibre batches show that the in-situ fibre resistance may differsignificantly from the strength of as-received and extracted fibres.
