Abstract
A shape forming tool for pre-carbonization compression of a fibrous preform includes a female forming tool comprising a die recess, a support structure moveable with respect to the female forming tool, and at least one bladder coupled to the support structure and configured to be received into the die recess. The support structure is configured to move the bladder(s) with respect to the female forming tool. The bladder(s) is/are configured to be inflated to apply a compressive force to compress and form a fibrous preform between the bladder(s) and the female forming tool.
