3K Carbon Fiber Pipe | Lightweight High Strength CFRP Round Tube with 3K Twill

Product Specification

3K Carbon Fiber Pipe | Lightweight High Strength CFRP Round Tube Composite Pipe Custom Size

3K carbon fiber tubes are lightweight, high-strength, hollow, or solid rods made from 3,000 filaments per tow of carbon fiber, commonly using a 2x2 twill weave for enhanced durability and a premium aesthetic. These tubes, often roll-wrapped with a glossy or matte finish, are widely utilized in RC models, robotics, aerospace, and specialized sporting equipment.

Our 3K Carbon Fiber Pipe is a high-performance CFRP (Carbon Fiber Reinforced Polymer) composite tube designed for applications that require a combination of lightweight structure, high strength, and excellent rigidity. Manufactured using premium 3K carbon fiber fabric and high-quality epoxy resin, each pipe is produced under precision-controlled processes to ensure consistent quality, superior mechanical performance, and long service life.

With its classic 3K weave pattern, this carbon fiber pipe offers both excellent structural properties and a premium carbon fiber appearance, making it suitable for industrial, aerospace, robotics, and consumer applications.

Key Characteristics and Benefits

• Material: 100% Carbon Fiber.
• 3K Definition: Each tow (thread) contains 3,000 filaments, offering an ideal balance between strength and flexibility compared to 1K or 12K alternatives.
• Durability: High-strength-to-weight ratio, high stiffness, and excellent corrosion resistance.
• Structure: Often manufactured through roll-wrapping techniques using unidirectional prepreg for structural strength, with a 3K weave on the outer layer for wear resistance.
• Surface Finishes: Available in matte or glossy finishes.
• Built for high-performance applications where strength, weight savings, and appearance all matter. Our 3K twill tubes combine a premium cosmetic weave with structural integrity suitable for aerospace, UAV, robotics, marine, and high-end industrial use.
