Vibration Dampening with Ekoa
Ekoa composites have outstanding damping properties for an engineering material with a unique stiffness-damping combination. With 20-30 % higher specific stiffness than fiberglass, Ekoa composites exhibit three times higher damping than carbon and fiberglass.
Ekoa as Fascia Layer
Ekoa composites are naturally very strong and stiff besting the stiffness of fiberglass. Solid laminates as thin as 1/16th" (1.5mm) can be used for structural applications.
Ekoa as Core Layer/s
Applications requiring the stiffness and strength of carbon—such as a high-performance bicycle frame—the dynamic properties of the structure can be greatly improved by replacing some carbon plys with Ekoa. Using the correct quantity of layers and orientation within the hybrid structure will generate constrained-layer damping.
Standard constrained damping layers are usually made from highly viscoelastic polymers with poor structural properties, relatively complicated to integrate during processing and adding a lot of weight to the structure. In comparison, Ekoa is light, has great structural properties, and can be processed in one-shot with carbon fiber.
