Abstract
A tool for forming a composite structure may include two or more segments formed from a polymer material. The tool may further include a crush insert disposed between the two or more segments. The tool may also include a support shaft coupled between the two or more segments. A method of forming a mandrel may include forming segments of the mandrel through an additive manufacturing process. The method may further include assembling the segments relative to one another. The method may also include positioning a crush insert between each of the segments. A method of fabricating a composite structure is also disclosed.
