ExoGrid has the ability to create "hybrid" metal/composite designs by exploiting the unique benefits of both materials.
Exogrid technology combines the best attributes of advanced composites with those of traditional metals. Exogrid structures start with a base metal (such as titanium) structure that then has a major portion of the surface area removed through advanced machining techniques, such as laser machining.
Removing heavy metal regions and replacing them with lighter composite materials allow designers to create lighter, stiffer or stronger products.
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 improved bending/torsion performance.
Exogrid Technology is able to take advantage of the primary benefits of metals (strength and consistency) as well as those of continuous fiber-based composites (weight savings and design flexibility). Exogrid Technology is particularly well suited to applications where lightweight and high-stiffness/ strength are critical such as bicycle seat-posts.
Multi-material Exogrid structures also possess unique vibration damping qualities due to the dissimilar natural frequencies of the fiber based composites and base metals. This vibration damping effect gives improved "feel" to bicycles frames and components when compared to the vibrations generated by single material metal surfaces.
