With decreasing fiber diameter it becomes increasingly difficult to post-fill a very long hollow fiber with a liquid.

We demonstrate the continuous production of liquid-filled polymeric fibers using an adapted melt-spinning approach.

The continuous liquid-core fiber exhibits enhanced energy dissipation properties compared to plain polymeric fibers.

This novel fiber represents a new type of damping element to be integrated into fiber-reinforced lightweight structures.
