Abstract

Vapor-phase synthesis is emerging as a method for the preparation of near final-shape, ceramic matrix composites for advanced structural applications. Oxide fiber-reinforced silicon carbide matrix composites are being developed for these applications. The mechanical properties of NextelTM 312 and NicalonTM fiber reinforced SiC matrix composites fabricated employing the forced-flow, thermal gradient chemical vapor infiltration (FCVI) process were compared at room temperature in pure tension. A carbon interface layer was used for both types of composites. Because of the available FCVI apparatus, only short-length specimens (7 to 8 cms) could be fabricated. Room temperature tensile strengths were measured and compared to room temperature flexure strength results for the two types of composites. The possible factors responsible for the differences in tensile strength for the two types of composites are discussed.
