A method has been developed to fabricate borosilicate glass matrix com
posites reinforced with monofilament SIC fibers by tape casting, Green
matrix tapes are laminated with fiber mats of a uniform fiber spacing
. The resulting laminate is sintered at 710 degrees C to >98% relative
density and HIP-consolidated to full density. The final specimens con
tain a high volume fraction of fibers (>35 vol%) in a uniform array. A
variation of this technique can be used to mount ''microcomposites''
(i.e., coated fibers) in a glass matrix to facilitate fabrication of p
ush-out test specimens.
