Abstract: A process is described for uniformly infiltrating 3000 filament carbon yarn with Ta and subsequent densification by hot pressing. Ta deposition rate is characterized as a function of deposition temperature, reactant flows, yarn pull rate, and coating chamber geometry for yarn pull rates from 2 to 50 m/h and Ta loadings from 40 to 350 wt % gain. Densification procedures for unidirectional pressings are described and data is presented which shows significant improvement in flexure strength over conventional TaC-C powder composites.
