High levels of damping are typically achieved by adding parasitic mass or material layers, which result in compliant or soft products; a problem for high-performance applications.
Countervail is a composite-material system that combines traditional damping layer concepts and a patented fiber preform. The experimentally-proven, unparalleled damping is derived from the fiber preform; the fiber pattern maximizes the vibrational energy dissipation in the surrounding polymeric materials.
Countervail layups can be tailored to balance stiffness, strength and damping performance that outperform constructions using traditional approaches.
Below are measured vibration characteristics of conventional and Countervail material systems.

Polymers and a patented advanced fiber reinforcement—that’s all. Countervail® can help you meet your dynamic response requirements at minimal weight.
Again, polymers and our patented fiber reinforcement—that’s all. If your product is already a composite material, or you want it to be, Countervail® can easily be integrated into your application.
Need to maintain stiffness but control vibrations—Countervail® can help you avoid the use of parasitic mass-adding damping treatments.
