Abstract
An improved method of making a bent graphite shaft in which a mandrel is provided as the basic form for forming the shaft. The mandrel includes a flexible portion at the location of the desired bend in the shaft. Graphite composite material is applied to the mandrel and to the flexible portion thereof. The flexible portion is then bent into a configuration which provides the desired bend, and the flexible portion is held in this configuration while the graphite composite material is cured in situ on the mandrel to form a rigid, graphite shaft. The mandrel is then slid out of the shaft with the flexible portion of the mandrel being sufficiently flexible to allow the mandrel to pass out of the shaft without fracturing the shaft.
