Abstract:

3-D weavingbraiding technology being pursued at ITAC has the potential to result in techniques for manufacturing low cost, high volume, near net shape, multiaxially reinforced through the thickness fibrous preforms, utilizing a cartesian weavingbraiding plane, for high temperature composite applications. These techniques lend themselves to the manufacture of hybrid preforms fiber assemblies that contain more than one shape or fiber architecture. With this tool, designers may optimize the fiber structure and shape of a preform along the length of composite parts to maximize performance. A low cost hand loom has been designed an built to demonstrate concepts empirical to this technology, laying the ground work for a fully automated 3-D cartesian weaving machine.
