Carbon Fiber Composite Hydraulic Cylinders
Lightweight Design Meets Precision Control
ANT COMPOSITES develops carbon fiber composite hydraulic cylinders, CFRP cylinder barrels and lightweight composite piston rods for applications that demand lower weight, precise motion and reliable performance.
By combining engineered carbon fiber laminates with precision metal components, we can significantly reduce cylinder mass while maintaining the stiffness, dimensional stability and load capacity required by demanding hydraulic systems.

Frequently Asked Questions
1. Do you manufacture complete hydraulic cylinders?
We can support CFRP cylinder barrels, lightweight piston rods and complete customized composite hydraulic cylinder assemblies. The available scope is confirmed after reviewing the application and drawing.
2. Can carbon fiber withstand hydraulic pressure?
Yes. Carbon fibers can be oriented around the barrel to resist internal pressure. The laminate thickness and winding angles must be calculated for the specified working pressure, peak pressure and fatigue life.
3. Is a metal liner required?
Not always. Depending on the pressure, sealing system and application, the cylinder barrel can use a metal liner, thin functional liner or custom linerless structure.
A lined hybrid structure is generally the most practical option when a proven internal sealing and wear surface is required.
4. Are composite hydraulic cylinders corrosion resistant?
CFRP does not rust. However, the complete cylinder also contains resin, seals and metal connections. These components must be selected and protected for the intended marine, chemical or outdoor environment.
5. Can the cylinders be used in magnetic environments?
Carbon fiber composites are non-magnetic. Suitable metal components must also be selected if the complete cylinder will operate near strong magnetic fields.

Custom Carbon Fiber LED Display Frame
Our custom carbon fiber LED display frames provide a lightweight and rigid structural solution for modular LED cabinets.
Compared with conventional metal structures, a properly designed carbon fiber frame can reduce cabinet weight while maintaining the stiffness required for accurate screen alignment. Lower structural weight can help reduce transportation costs, truss loads, and installation effort.
Each frame can be developed around the customer’s LED module arrangement, cabinet dimensions, locking system, mounting points, and service requirements. (Frame body only. LED modules, power supplies, control systems, and display electronics are not included unless otherwise agreed.)
Custom Carbon Fiber Luggage
Our carbon fiber luggage combines real composite panels with a strong framed structure. The visible woven surface gives the suitcase a technical and premium appearance, while the surrounding frame protects the panel edges and supports the hardware.
The pictured model uses woven carbon fiber panels, a dark metal frame, reinforced corners, a telescopic handle and four spinner wheels. Its structure, dimensions and accessories can be adjusted for OEM and private-label projects.
This product is suitable for brands looking for luggage that stands apart from common plastic or aluminum-shell designs.
Cuttlefish Carbon Fiber Speargun Barrel
Our cuttlefish carbon fiber speargun barrel combines a standard round carbon fiber tube with streamlined side wings. This profile creates the recognizable cuttlefish shape while keeping the front and rear connection areas compatible with the required speargun components.
An integrated rail runs along the top of the barrel to guide the spear shaft. The carbon fiber structure offers low weight, high stiffness and good resistance to the marine environment.
We manufacture barrels according to your required length, cross-section, connection dimensions and surface finish.
Round Carbon Fiber Speargun Barrel
ANT Composites manufactures round carbon fiber speargun barrels for spearfishing equipment, replacement barrels, and OEM speargun projects.
The barrel uses a continuous round carbon fiber tube as its main structure. Two low raised shoulders run along the top and form a shallow guide track for the spear shaft. This integrated design helps keep the shaft aligned without adding a separate external rail.
Standard and custom diameters, lengths, wall thicknesses, carbon finishes, and guide profiles are available.
