Pultruded Square inner round Hollow carbon Fiber Tube 10*10mm(OD) * 8.5mm(ID) * 1000mm(L)

This pultruded square hollow carbon fiber tube features a 10mm outer diameter with an 8.5mm inner diameter and 1000mm length, engineered using advanced pultrusion technology for consistent fiber-matrix integration and superior structural integrity. Professional engineers and composite specialists utilize these tubes in aerospace components, robotics arms, drone frames, and precision mechanical assemblies where weight reduction and high stiffness-to-weight ratios are critical performance parameters. This product solves the challenge of needing lightweight yet rigid structural members that maintain dimensional stability under thermal and mechanical stress while eliminating the corrosion concerns associated with metal alternatives.

Product Overview

Pultruded carbon fiber tubes are manufactured through a continuous pultrusion process where carbon fiber rovings are drawn through a heated resin bath and then through a shaped die, creating a unidirectional fiber composite with exceptional longitudinal strength and stiffness. The square cross-section with rounded inner corners provides superior load distribution characteristics compared to simple hollow tubes, while the 1.25mm wall thickness delivers optimal strength-to-weight balance for structural applications. The pultrusion manufacturing method ensures consistent fiber volume fraction, uniform wall thickness, and repeatable mechanical properties across the entire 1000mm length, making these tubes ideal for precision engineering applications where tolerance and performance predictability are essential.

The square geometry with inner round configuration maximizes moment of inertia for bending resistance while maintaining the handling and assembly advantages of a square profile. Carbon fiber composites exhibit superior fatigue resistance compared to aluminum or steel, making them exceptionally suitable for cyclic loading applications. The 10x10mm outer dimension provides excellent stiffness characteristics while remaining lightweight, with typical density around 1.6 g/cm3 compared to 2.7 g/cm3 for aluminum, resulting in approximately 40% weight savings for equivalent structural performance in most applications.

How to Use

Before integrating this pultruded carbon fiber tube into your assembly, inspect the entire 1000mm length for any surface damage, delamination, or manufacturing defects. The tube arrives ready for use with a smooth composite surface that requires no additional finishing. For mechanical assembly, use standard drilling techniques with carbide-tipped drill bits at moderate speeds (1000-2000 RPM) to create mounting holes, and always use backing plates to prevent delamination at exit points. Apply cutting compound or water-based coolant during drilling operations to extend tool life and maintain hole quality. The tube can be cut to shorter lengths using a fine-toothed saw or abrasive cutoff wheel with water cooling to prevent resin matrix degradation.

For adhesive bonding applications, prepare the surface using light sanding with 120-150 grit sandpaper to remove any mold release agent, then clean thoroughly with acetone or isopropyl alcohol before applying structural epoxy or polyurethane adhesives. For mechanical fastening, use stainless steel or titanium hardware to prevent galvanic corrosion at the composite interface, and apply thread-locking compound to prevent vibration-induced loosening in dynamic applications. When designing load-bearing assemblies, account for the unidirectional fiber orientation which provides maximum strength along the tube length but reduced transverse strength; reinforce with additional composite plies or metal inserts for applications involving significant lateral loads. Always store the tubes in a dry environment away from direct sunlight, as UV exposure can degrade the resin matrix over extended periods.
