Authentic product, 7-day warranty on manufacturing defects, fast delivery across India.\"\u003e\n\n\u003ch1\u003ePultruded Square Inner round Carbon Fiber Hollow Tube 10*10mm(OD) * 8.5mm(ID) * 1000mm(L)\u003c\/h1\u003e\n\n\u003cp\u003eThis pultruded carbon fiber hollow tube features a 10mm outer square dimension with an 8.5mm inner round bore, delivering exceptional strength-to-weight ratios ideal for aerospace, robotics, and precision engineering applications. Aerospace engineers, drone manufacturers, and structural design specialists rely on this profile for load-bearing components that demand minimal weight without compromising rigidity. The 1.25mm wall thickness solves the critical engineering challenge of creating lightweight yet torsionally stiff structures for dynamic applications requiring high modulus carbon fiber reinforcement.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Overview\u003c\/h2\u003e\n\u003cp\u003ePultruded carbon fiber tubes are manufactured through continuous pultrusion processes where carbon fiber rovings are drawn through a heated resin bath and then through a shaped die, creating uniform, defect-free composite structures with consistent fiber alignment. This manufacturing method ensures superior mechanical properties compared to wound or wrapped alternatives, with fibers oriented primarily along the longitudinal axis for maximum tensile and compressive strength. The square outer profile with round inner bore provides unique geometric advantages for mounting, fastening, and load distribution while maintaining the aerodynamic benefits of the internal rounded surface.\u003c\/p\u003e\n\n\u003cp\u003eThe 10x10mm square cross-section offers optimal structural efficiency for applications requiring both bending stiffness and torsional resistance, while the 1000mm length provides versatile sizing for drone arms, structural supports, precision measurement instruments, and composite framework assemblies. The round inner diameter eliminates stress concentrations at internal edges and facilitates smooth insertion of shafts, cables, or connecting rods. With a wall thickness of 1.25mm, this tube achieves an exceptional stiffness-to-weight ratio, typically weighing under 50 grams per meter while maintaining rigidity comparable to aluminum tubes three times heavier.\u003c\/p\u003e\n\n\u003ch2\u003eKey

stresses, and dynamic impact forces to confirm the 10x10mm profile with 1.25mm wall thickness provides adequate safety margins. The round 8.5mm inner bore accommodates standard shaft diameters up to 8mm, allowing direct insertion of steel pins, aluminum rods, or composite shafts without additional machining. For mounting applications, the square outer profile enables straightforward attachment of brackets, clamps, and fastening hardware using standard M3 or M4 threaded inserts positioned at predetermined intervals along the tube length.\u003c\/p\u003e\n\n\u003cp\u003eWhen cutting or machining the carbon fiber tube, use carbide-tipped tools with controlled feed rates to prevent delamination at cut edges. A fine-toothed saw or CNC milling machine with coolant application produces clean edges without fiber fraying. For joining multiple tube segments, consider carbon fiber-compatible adhesives like epoxy structural adhesives, mechanical fasteners through drilled holes, or composite sleeve couplers for seamless load transfer. Always support the tube adequately during machining to prevent vibration-induced damage, and wear appropriate respiratory protection when cutting carbon fiber composites to avoid inhaling fine particles. Allow adhesives to cure fully per manufacturer specifications before applying structural loads to ensure maximum joint strength and durability.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the weight difference between this carbon fiber tube and an equivalent aluminum tube?\u003c\/summary\u003e\n\u003cp\u003eThis carbon fiber tube weighs approximately 45-50 grams per meter, while an equivalent aluminum tube of similar outer dimensions would weigh approximately 220-250 grams per meter. This represents an 80 percent weight reduction while maintaining comparable or superior stiffness characteristics, making carbon fiber ideal for weight-critical applications like drones, aerospace structures, and precision instruments.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan this tube be machined or cut to custom lengths?\u003c\/summary\u003e\n\u003cp\u003eYes, the pultruded carbon fiber tube can be cut using fine-toothed saws, band saws, or CNC milling machines with carbide tools. For clean cuts without delamination, use controlled feed rates and coolant application. We recommend professional machining services for precision requirements. Custom cutting services are available through our technical support team for orders of 5 or more units.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the maximum continuous load this tube can support?\u003c\/summary\u003e\n\u003cp\u003eThe maximum load depends on your specific application geometry, support conditions, and safety factor requirements. With tensile strength exceeding 600 MPa and flexural modulus greater than 25 GPa, this tube can typically support static bending loads of 50-80 kilograms when supported at both ends with a 1000mm span, depending on load distribution. For precise load calculations, consult our technical team with your specific application parameters.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eIs this tube suitable for outdoor or marine applications?\u003c\/summary\u003e\n\u003cp\u003eYes, the epoxy resin matrix provides excellent resistance to moisture, salt spray, UV radiation, and chemical exposure without requiring protective coatings. However, for long-term marine applications, we recommend periodic inspection for any surface degradation and application of UV-protective clear coatings in extreme sun exposure environments. The carbon fiber composite is inherently corrosion-resistant, unlike aluminum or steel alternatives.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan fasteners be directly threaded into this tube?\u003c\/summary\u003e\n\u003cp\u003eDirect threading into carbon fiber is not recommended as the composite material may delaminate under threaded fastener loads. Instead, use threaded inserts (brass or stainless steel) installed with epoxy adhesive, or drill through-holes and use external fastening methods. For applications requiring multiple attachment points, pre-installed threaded inserts provide reliable, reusable fastening without damaging the tube structure.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhen will I receive my order?\u003c\/summary\u003e\n\u003cp\u003eOrders are dispatched within 1-5 business days from our Bengaluru warehouse.
