A composite core for forming a passage in an investment casting mold is provided including a core element. A generally hollow structural element is positioned about an exterior of the core element. The structural element is configured to deform when a force is applied to the structural element. A rigid shell element is integrally formed about the structural element. The shell element is configured to break when the structural element deforms.
