Abstract
Graphite fibers (62) are mixed with other materials (22) to form gas generating material (10) for use in an air bag inflator. The graphite fibers are first chopped to a desired short length by forming a mixture of fluid and relatively long graphite fibers in a container (50) having therein a rotatable blade (58), and rotating the blade continuously for a period of time to chop the graphite fibers to a shorter and more uniform length. The viscosity of the mixture in the container is increased as the blade rotates in the container, preferably through evaporation or boiling which counteracts the viscosity decreasing effect of fiber shortening.
