Filament Wound Large Diameter Carbon Fiber Tubes

 

Why Choose Large Diameter Filament Wound Carbon Fiber Tubes?

Not all carbon fiber tubes perform the same way. Roll-wrapped carbon fibre tubes work well for small, thin-walled applications. But for large diameters and heavy loads, filament wound carbon fiber boom is the better choice.

 

Benefit for Heavy Machinery

Continuous fiber placement. No weak seams or overlaps, truly monolithic structure.

Precise fiber angle control. Optimized for bending (±45°), torsion (hoop), or axial loads (0°)

Diameters up to 1000 mm with lengths up to 14000 mm. One-piece construction reduces assembly and welding.

High fiber volume fraction (55–65%). Highest structural efficiency per kilogram of weight.

Runfeng CFRP's filament wound carbon fiber pipes are not lab experiments. They are field-proven components already operating in demanding industrial environments.

Application Case 1: Concrete Pump Boom - Weight Reduction

 

Background:

A concrete pump manufacturer wanted to extend their boom reach without adding weight to the truck chassis or increasing counterbalance. The existing steel boom section weighed 340 kg.

 

Solution:

We designed and manufactured a filament wound carbon fiber boom section with the same outer diameter and mounting interfaces as the original steel part. The laminate was optimized for combined bending and torsion, with extra hoop reinforcement around the pin connection areas.

 

Results:

Weight reduced from 340 kg to 148 kg, a 56% saving.

Same stiffness under pumping loads (validated by strain gauge testing).

Lower hydraulic cylinder force required.

Faster boom cycle time due to reduced inertia.

No corrosion issues from concrete washout and chemicals.

 

The customer has since replaced three additional boom sections with filament wound carbon fiber pipes and is now developing a full composite boom assembly.

Application Case 2: Agricultural Sprayer Boom - Stiffness and Stability

 

Background:

A self-propelled sprayer manufacturer struggled with steel boom deflection during field operation. The 24 meters steel boom deflected up to 380 mm at the tips, causing uneven chemical application and inconsistent nozzle height.

 

Solution:

We replaced the steel main beam with a large diameter carbon fiber pipe using a custom layup sequence. This filament wound large diameter carbon fiber tube was designed with higher axial and bending stiffness than the original steel section, despite being 52% lighter.

 

Results:

Tip deflection reduced from 380 mm to 175 mm, a 54% improvement.

Lighter boom allowed faster field speeds without compromising stability.

Reduced stress on folding hinges and lift cylinders.

No surface preparation needed for painting. The carbon fiber finish is UV-stable and chemical-resistant.

The sprayer boom now maintains consistent nozzle height across its full width, improving chemical coverage and reducing waste.
