Exogrid is an exciting patented technology (US Pat. No. 6,896,006) that combines the best attributes of advanced composites with those of traditional metals. Exogrid structures start with a base metal (such as titanium or steel) structure that then has a major portion of the surface area removed through advanced techniques, such as laser machining. The resulting lightweight metal shell is then fused (using the company’s patented Bi/Fusion™ Technology) with an advanced composite inner structure molded during a secondary process using elevated temperature and pressure.

Because of the characteristics of the different materials, multi-material Exogrid structures are lighter than their pure metal counterparts and have significantly improved performance in both bending and torsion. Multi-material Exogrid structures also possess unique vibration damping qualities due to the dissimilar natural frequencies of the fiber based composites and base metals.
