Nylon Filament Helical & Hoop Winding Process

- The elastomer used in the fender skin in polyurea. The skin is reinforced by filament winding wrap in a helical and hoop direction, which is controlled by and automatic winding system with load cell sensors at each filament. Our four-axis filament winding system, also used to build spacecraft fuel tanks, takes control and positions each filament for maximum strength and an even finish.

- Foam-filled fenders do not experience a high reaction force during normal docking because they have high energy absorption with low reaction force and hull pressure.

- The reaction force curve shows a gradual performance increase as deflection rate increases. Unlike foam-filled fenders, rubber fenders have high reaction force with low deflection rates, increasing the risk of damage to docks, piers, and vessels during docking.

Performance test

Test procedures : Select Fender → Move to the Machine → Measure Height → Compression → Read Reaction Force (60%) → Decompress → Measure Recovery Rate to Full Height

Compression Performance Test

- To ensure fenders are able to prevent damage to docks, piers, and vessels, these tests measure the quality and durability of a fender’s ability to absorb energy and reduce reaction force.

- Energy absorption and compression load must be able to reach 60% deflection.

- At 60% deflection, the fender will be decompressed. After two minutes, the height of the fender is measured and must recover 90% of its original height. After thirty minutes, fender height recovery must exceed 95%.
