Vibration Dampening with Ekoa®
Ekoa® has 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—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 and enhance the dynamic properties of the structure .
Standard constrained damping layers are usually made from highly viscoelastic polymers with poor structural properties, making it 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.
