Custom Matte Forged Ud Carbon Fiber Round Tube 25mm for Machinery Structure

Custom Matte Forged UD Carbon Fiber Round Tube 25mm for Machinery Structure

• High Strength-to-Weight Ratio: Carbon fiber tubes deliver superior mechanical strength while remaining significantly lighter than steel or aluminum, providing structural efficiency without added mass.

• Dimensional Stability: The composite structure resists deformation under load and temperature variation, ensuring long-term precision in high-performance applications.

• Vibration Damping: The layered carbon weave naturally absorbs vibration, improving stability for camera rigs, robotic arms, and UAV assemblies.

• Corrosion & Fatigue Resistance: Unlike metals, carbon fiber does not rust or fatigue, maintaining its performance even in humid or chemically exposed environments.

• Aesthetic Finish Options: Available in glossy or matte 3K twill, plain, or forged surface finishes, offering both functional and visual advantages.

• Customizable: Tubes can be produced in a wide range of diameters, wall thicknesses, and lengths, supporting both prototype and mass-production requirements.

Material & Manufacturing

All Justar carbon fiber components are produced from aerospace-grade T300, T700, or T800 carbon fiber prepreg combined with high-temperature epoxy resin systems. The blend of unidirectional and 3K twill woven fabrics ensures a perfect balance of stiffness, impact resistance, and surface aesthetics.

Key material features include:

• Controlled resin content for maximum fiber volume fraction.

• Multi-layer layup design for enhanced isotropic mechanical strength.

• Optional hybrid construction with fiberglass or Kevlar reinforcement.

• Thermal curing in autoclave or precision oven for complete consolidation.

• Peel-ply or sanding finish available for secondary bonding.

Each tube and plate is CNC trimmed and precisely polished to ensure accurate dimensions, clean edges, and perfect fit for further processing.

Remark:
These are our regularly available sizes. If your required dimensions are not listed here, we can manufacture according to your custom specifications, including both small prototypes and large-format sheets.

1. Material preparation - Cutting of T300/T700 prepreg sheets to required ply patterns.

2. Layup and wrapping - Layers are rolled or wrapped around steel mandrels according to diameter.

3. Curing - High-temperature autoclave curing removes voids and ensures fiber alignment.

4. Demolding - Controlled cooling prevents deformation and warping.

5. Post-processing - CNC machining, sanding, slotting, tapering, or polishing.

6. Surface finishing - Matte, glossy, forged, or peel-ply finishes available.

7. Inspection and packaging - Dimensional and surface quality verification before export.

This production workflow guarantees mechanical stability, excellent surface finish, and reliable repeatability.

Each tube or sheet is optimized for strength distribution, providing excellent vibration damping and reliable performance even in cyclic-load conditions.
