Filament wound composite tubes offer excellent stiffness and strength. They are used in lightweight frames, UAVs, robot arms, shafts, motorsports, spinnaker booms, SUP oars, kayak paddles, and more.
At Spilka Composites, we specialize in the design and manufacturing of high-quality composite tubes. Most of our products are custom designed and rigorously tested to meet specific customer requirements.
Filament wound tubes are used in light weight frames, UAVs, robot arms, shafts, motor sports, spinnaker booms, SUP oars and kayak paddles and many more.
Our products are crafted from carbon fiber, glass fiber, aramid, or hybrid composites, available in various standard and custom diameters and lengths.
The tubes are custom-made with materials and layup tailored to your specific application.
The winding process precisely places fibers around the tube at predefined angles and under tension to ensure accurate placement. Low winding angles enhance axial stiffness, while higher angles are ideal for pressure and torsion applications.
There are numerous design choices available for composite tube construction.
Typical reinforcements like glass fibers and carbon fibers can be enhanced further with mats and fabrics.
We use prepreg fibers with epoxy resin, including standard modulus carbon fiber (Toray T700 or similar), S-glass, and aramid fibers. The epoxy resin withstands temperatures up to 100 degrees C, with special resins available upon request.
We offer tubes with an unsanded, sanded, or painted finish.
We produce custom-designed sample holders for laboratory equipment, tailored to specific needs. Made from carbon fiber composites, these holders are transparent to X-rays, lightweight, and easy for the operator to handle.
Filament wound composite tubes have excellent stiffness and strength, with fibers precisely placed at specific angles. Low angles increase lengthwise stiffness, while higher angles improve resistance to pressure and twisting.
Our tubes are custom-made with materials and fiber layup specifically tailored to meet your requirements. Standard sizes range from 12 mm in diameter and up to 1200 mm in length; however, we can produce tubes with diameters up to 2 meters and lengths up to 4 meters.

Surface treatment of composite tubes is an important process for enhancing the properties of the materials and ensuring they meet specific requirements for various applications.
The surface treatment can be tailored to specific needs depending on the type of composite material used and the specific requirements of the application.
