Zavedení: What Is Carbon Fiber Tubing?

Carbon fiber tubing is a high-performance structural material made by layering carbon fiber fabrics or filaments with resin and curing them into hollow cylindrical or shaped tubes. Thanks to its exceptional strength-to-weight ratio, stiffness, corrosion resistance, and fatigue performance, carbon fiber tubing has become a preferred solution across industries such as drony, robotics, aerospace, automotive, sports equipment, medical devices, and industrial automation.

From a carbon fiber factory / OEM manufacturing perspective, tubing is one of the most versatile composite products. It can be produced in various diameters, wall thicknesses, fiber orientations, and surface finishes, allowing engineers to tailor mechanical properties precisely to application requirements.

1. Types of Carbon Fiber Tubing

Carbon fiber tubing can be classified by fiber structure, shape, and manufacturing method.

1.1 By Fiber Structure

Unidirectional (UD) Carbon Fiber Tubing

• Fibers aligned primarily along the tube length
• Excellent axial tensile and bending strength
• Ideal for drone arms, UAV booms, camera supports, and load-bearing structures

Woven Carbon Fiber Tubing (Twill / Plain Weave)

• Fibers interlaced at 0°/90° or ±45°
• Balanced strength in multiple directions
• Better impact resistance and aesthetics

Hybrid Layup Carbon Fiber Tubing

• Combination of UD and woven layers
• Optimized stiffness, torsion resistance, and durability
• Common in professional drone frames and industrial equipment

---

1.2 By Shape

• Round carbon fiber tubes (most common)
• Square or rectangular carbon fiber tubes
• Oval or custom-shaped tubes (OEM tooling required)

From an OEM factory standpoint, round tubes offer the best cost-performance ratio, while custom profiles are suitable for high-volume projects.

---

1.3 By Manufacturing Method

• Roll-wrapped carbon fiber tubing
• Pultruded carbon fiber tubing
• Filament-wound carbon fiber tubing

Each method affects strength consistency, surface quality, and cost, which we will discuss later.

2. Carbon Fiber Tubing Sizes and Dimensions

Carbon fiber tubing is highly customizable.

2.1 Outer Diameter (OD)

Common OD ranges:

• Small tubes: 4mm – 10mm
• Medium tubes: 12mm – 30mm
• Large tubes: 40mm – 100mm+

OEM factories typically maintain standard molds for popular sizes while offering custom diameters for bulk orders.

---

2.2 Inner Diameter (ID) & Wall Thickness

Wall thickness usually ranges from:

• 0.5mm – 1.0mm (ultra-lightweight applications)
• 1.5mm – 3.0mm (structural and drone arms)
• 3.0mm – 6.0mm+ (industrial and load-bearing systems)

Choosing the correct thickness directly impacts stiffness, buckling resistance, and cost.

2.3 Délka

• Standard lengths: 500mm, 1000mm, 2000mm
• Custom cut-to-length available via CNC cutting or waterjet trimming

---

3. Thickness and Structural Performance

Wall thickness is a critical design variable.

• Thinner tubes prioritize weight reduction
• Thicker tubes improve crash resistance and vibration damping
• Multi-layer layups enhance torsional rigidity

From a manufacturing perspective, advanced layup design allows us to increase strength without unnecessary weight, outperforming metal alternatives.

4. Surface Treatment and Finishing Processes

Carbon fiber tubing surface finish impacts both appearance and bonding performance.

4.1 Common Surface Finishes

• Glossy finish (clear-coated, premium appearance)
• Matte finish (anti-glare, popular in drones)
• 3K twill visible weave
• UD texture surface

---

4.2 Secondary Surface Treatments

• Sandblasting or abrasion (for adhesive bonding)
• UV-resistant clear coating
• Anti-scratch resin coating
• Paint or anodized-look finishes (OEM projects)

A professional carbon fiber factory ensures uniform resin distribution and smooth internal walls, which is critical for mechanical performance.
