FILAMENT WINDING APPARATUS AND METHOD FOR CERAMIC MATRIX COMPOSITES

摘要

An apparatus for making a composite article includes a monofilament feed track adapted to carry a spaced array of ceramic monofilament strands, a fiber yarn feed track adapted to carry a spaced array of fiber yarn tows impregnated with a plurality of glass particulates, a mandrel, and a heater assembly. The mandrel is adapted to wind together individual glass-impregnated fiber yarn strands and individual ceramic monofilament strands to form a dual-fiber weave. The heater assembly is adapted to heat at least the glass particulates such that pressure from the wound array of ceramic monofilaments is sufficient to consolidate the glass particulates and the dual-fiber weave into a dual-fiber ceramic matrix composite (CMC).

1. An apparatus for making a composite article, the apparatus comprising:
a monofilament feed track adapted to carry a first spaced array of ceramic monofilament strands; a fiber yarn feed track adapted to carry a second spaced array of fiber yarn tows impregnated with a plurality of glass particulates; a mandrel disposed at an end of the monofilament feed track and an end of the fiber yarn feed track, the mandrel adapted to wind together individual tows of the first spaced array of glass-impregnated fiber yarn tows and individual strands of the array of ceramic monofilament strands to form a dual-fiber weave; and a heater assembly disposed within or adjacent to the mandrel, the heater assembly adapted to heat at least the glass particulates such that pressure from the wound array of ceramic monofilaments is sufficient to consolidate the glass particulates and the dual-fiber weave into a dual-fiber ceramic matrix composite (CMC).
