have a density of 2g / m3 compared to aluminum ’ s 2.7g / m3 , making it almost half the weight of aluminum while maintaining a similar mechanical strength . Carbon fiber , on the other hand , has a density of 1.55g / m3 , with a much greater strength and stiffness than aluminum or glass fiber composites .
Continuous manufacturing technologies like pultrusion and pull-winding offer significant benefits for small-diameter tube production . Pultrusion typically results in wall thicknesses of two millimeters and above , whereas pull-winding , a form of continuous filament winding , can achieve much thinner walls , as thin as 0.5 millimeters .
Pull-winding involves the simultaneous application of resin and reinforcement fibers , such as glass or carbon fiber , onto a mandrel . As the crosswinder winds fibers helically around the static mandrel , a composite material is formed , exhibiting augmented strength and resistance to bending . Additionally , axial fibers along the length of the small-diameter tube ensure the mechanical integrity of the tube and , together with wound transverse fibers , gives the possibility to optimize the structure of the tube while concurrently reducing both weight and material usage . This combination of techniques ensures a high output rate and consistent quality , making pull-winding an ideal choice for industries requiring lightweight yet durable solutions .
Small-diameter pull-wound composite tubes offer tailored solutions across industries , including robotics , aerospace , and medical technology , meeting specific client needs with customizable parameters for the specific application . This adaptability ensures tubes are precisely suited for each application , from precise movements in robotics to agile flight maneuvers in drones .
Quality control is paramount throughout manufacturing . Rigorous measures ensure reliability and consistency , with advanced testing techniques verifying dimensional accuracy , mechanical properties , and adherence to any industry standards . This approach guarantees that tubes meet or exceed performance expectations .
