It is strong enough with a light weight, widely used for idler rollers, extension poles, tripod tubes,UAV components. Details Roll wrapped tube is manufactured using multiple layers of prepreg carbon fiber materials. Most of our larger diameters tubing are made by roll-wrapped technology, because of their alternating layers of reinforcement that could keep the tubing with a more resilient performance, especially to crush and twist forces. We are also able customize the fiber layers according to customer’s requirements. Qualifications Using powered platen rolling presses to construct the tube, and CNC tape winders for consolidation.Curing of tubes under heat and pressure in high temp ovens with data loggers. The larger diameters tubing are produced according to a proprietary sheet winding process, that could guarantee our tubing within tight tolerances. Delivery, shipping We offer stock, build-to-order, and custom carbon fiber tubes in multiple diameters. Custom tooling can be made to order for reasonable cost. Generally 5-10 days if the goods are in stock. or 15-20 days if the goods are not in stock. FAQ Q: could you do customized diameter and length carbon tubes? A: Yes, we could. Q: Do you provide samples ? is it free or extra ? A: Yes, we could offer the sample but do not pay the cost of freight. Q: What express company you use? A: DHL, Fedex, UPS
