Buy carbon fiber round tubes online from our UK and US stock, offering instant access to 6mm - 100mm diameter options for fast-turnaround projects. These tubes combine convenience with high performance, stocked in popular sizes to serve industries from hobbyists (RC models, 3D printing) to professionals (aerospace prototyping, medical devices). The 6mm tubes suit delicate applications like drone propeller shafts or camera stabilizers, while 100mm tubes cater to structural supports or industrial rollers. Constructed from 3K or 12K carbon fiber (depending on size) with epoxy resin, they balance strength and weight: 6mm tubes weigh just 5g/m, while 100mm tubes offer 3,000 MPa tensile strength for heavy loads. Stock includes both filament-wound (for uniform strength) and roll-wrapped (for precise weave patterns) variants, with lengths from 500mm to 2m. UK stock ships from London (next-day delivery for orders <5kg), and US stock from Chicago (2-3 day ground shipping), with worldwide express options. Custom cutting (to ±1mm tolerance) and chamfering services are available at checkout, eliminating post-purchase processing.
