Pultruded Carbon Fiber Tube (Hollow) 10mm(OD) * 8mm(ID) * 1000mm(L) (Pack of 2)

This pultruded carbon fiber hollow tube is a high-strength, lightweight structural component manufactured through continuous pultrusion process, delivering consistent fiber-to-resin ratios and superior mechanical properties. Professional engineers and roboticists utilize these tubes in precision applications including UAV frames, robotic arms, aerospace components, and high-performance mechanical assemblies where weight reduction and stiffness are critical. The product solves the engineering challenge of achieving maximum strength-to-weight ratio while maintaining dimensional accuracy and cost-effectiveness in demanding structural applications.

Product Overview

Pultruded carbon fiber tubes are manufactured using the pultrusion process, where continuous carbon fiber strands are pulled through a resin bath and heated die, creating a uniform, void-free composite structure with excellent longitudinal strength and dimensional consistency. The hollow design of this 10mm outer diameter tube with 8mm inner diameter provides optimal material utilization, delivering high bending stiffness and torsional rigidity while minimizing weight compared to solid alternatives. The 1mm wall thickness ensures structural integrity for dynamic loading conditions while maintaining the lightweight characteristics essential for aerospace, robotics, and precision engineering applications.

What distinguishes this pultruded tube from other carbon fiber products is the manufacturing precision inherent to the pultrusion process, which produces superior fiber alignment and eliminates the porosity issues common in hand-layup or filament-wound alternatives. The 1000mm length provides flexibility for custom cutting and assembly in modular designs, while the pack of 2 offers value for prototype development, testing phases, or small-scale production runs. The tube exhibits excellent chemical resistance, thermal stability across -40 to 120 degrees Celsius, and maintains dimensional accuracy with tight tolerances suitable for precision-fit applications.

How to Use

Before integrating the pultruded carbon fiber tube into your assembly, inspect both ends for any sharp edges and deburr if necessary using fine sandpaper or a deburring tool to prevent fiber fraying. If cutting the tube to custom lengths, use a fine-toothed saw or rotary cutting tool with a carbide blade, maintaining steady feed rates to prevent splintering. For drilling holes, mark precise locations using a center punch, use a sharp carbide drill bit with cutting fluid, and apply moderate pressure to prevent delamination at the exit hole. When bonding the tube to other components, prepare the surface by lightly sanding with 120-150 grit sandpaper to enhance adhesive contact, clean with isopropyl alcohol, and apply epoxy adhesive or structural bonding agents rated for carbon fiber composites.

For mechanical fastening, use stainless steel or titanium fasteners to prevent galvanic corrosion, and apply thread-locking compound on bolts to prevent vibration-induced loosening in dynamic applications. If the tube requires threading internally or externally, use carbide taps and dies with appropriate cutting fluid, maintaining slow rotational speeds to prevent material damage. Store the tubes in a dry environment away from direct sunlight and extreme temperature fluctuations to preserve resin integrity. When designing assemblies, account for the anisotropic nature of pultruded tubes, which exhibit maximum strength along the fiber direction (lengthwise) and lower strength in transverse directions, ensuring load paths align with fiber orientation for optimal performance.
