This research investigates the methods of fabrication for non-traditional, non-rectangular bistable structures using Carbon Fiber Reinforced Polymers. Currently, the non-rectangular shapes that have been used are rhombi (diamonds), triangles, and circles. Each shape is cut from a 12x12 inch sheet of composite laminate. The shape, when cut, must maintain a 12-inch dimension in one aspect of height, diameter, or length. As these shapes are fabricated and postprocessed, it is observed that the boundary conditions, performance, curvature and options for fixturing vary significantly. It has also been observed that much of the remaining material from post-processing cutting methods also retain much of its disability, allowing for usage in alternative capacities.
