How submarines dock？

08/01/2025What are composite fenders?
1. Introduction
Composite fenders are protective cushions used on docks, piers, and boats. They combine a resilient rubber body with a wear‑resistant UHMW‑PE face. This mix gives both strong impact absorption and low friction for safe, smooth docking.
2. What Are Composite Fenders?
Composite rubber fenders use a flexible rubber body combined with a tough, smooth UHMW‑PE (ultra‑high molecular weight polyethylene) surface. These materials are joined through a special vulcanizing process, creating a strong bond at the molecular level. This method offers better strength and long-term performance than traditional mechanical fixing.
3. Main Features & Benefits
- High energy absorption, low reaction force
The rubber core absorbs shocks well. The UHMW‑PE face cuts down friction, which reduces wear on both the fender and the vessel. - Wear and corrosion resistance
UHMW‑PE resists abrasion and salt water. It holds up in harsh marine settings better than plain rubber or wood. - Easy to install and adapt
You can drill, cut, or shape them on site. They come in many standard sizes, so they fit docks, pontoons, or tug boats quickly. - Lower maintenance
They resist damage and need fewer repairs over time, which cuts upkeep costs.
4. Where They’re Used
Composite fenders suit many marine situations:
- Small jetties, wharves, pontoons, floating platforms
- Inland waterways and tugboat berths
- Landing platforms where low wear is needed
5. Composite vs. Other Fender Types
| Fender Type | Material | Pros | Cons |
|---|---|---|---|
| Composite Fender | Rubber + UHMW‑PE face | Low friction, long life, easy fit | Cost more than simple rubber extrusions |
| Solid Rubber Fender | Rubber | Simple, strong energy absorption | High friction, more wear on hulls |
| Foam‑filled Fender | Foam inside rubber skin | Light, unsinkable, good impact absorption | Lower abrasion resistance |
| Pneumatic Fender | Inflatable rubber | Very elastic, flexible deployment | Needs pressure, more maintenance |
Composite fenders give a balance: strength, ease of use, and reduced wear. Other types may specialize, but composite is often ideal for small and mid-size berthing areas.
6. Summary & Why It Matters
Composite fenders offer smart protection for docks and small vessels. They absorb shock, cut down friction, resist wear, and last long. Plus, you can fit them easily and save on upkeep.
If you plan a marina, pontoon, or tug boat dock, composite fenders offer real value. Their mix of durability and low maintenance makes them ideal for many marine settings.
