  • Patent number: 12285903
    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.
    Type: Grant

  • Patent number: 11951582
    Abstract: A core support system includes a support structure. The support structure includes a frame and a support member having a saturatable engagement layer disposed over the frame. A method of machining a core material incudes applying a fluid to an engagement layer of a support structure and saturating the engagement layer with the fluid, disposing a core material on the engagement layer, causing the fluid to freeze to secure to the core material to the support structure, machining the core material, melting the frozen fluid to release the core material from the support structure, and removing the core material from the engagement layer.

  • Publication number: 20170080647
    Abstract: An induction heating compaction system is provided. The system includes an induction heating member and a compaction member. The induction heating member is configured to generate an electromagnetic field at a select frequency. The select frequency causes at least one of the fibers and matrix in pre-preg material to heat up. The compaction member has at least a portion that is made from a material that is transparent to the select frequency of the electromagnetic field generated by the induction heating member. The compaction member includes a cooling assembly that is configured and arranged to extract heat from the pre-preg material, while compacting the pre-preg material.
