Composites in Urban transport
The coiled cylindrical structures form tubes when joined end to end diametrically. When fibers of carbon are embedded in resin, it form a composite of carbon fiber tubes. They are known for their exceptional strength-to-weight ratio and high stiffness and durability. With technological advancements, the improvement of materials for a sustainable environment is increasing day by day. Carbon fiber tubes have grabbed attention in this regard. They are widely used in aerospace, automotive, sports equipment, grid infrastructures, and medical instruments. Carbon fiber tubes are manufactured by pultrusion, roll-wrapping, or filament winding. Continuous carbon fiber filaments are winded around a mandrel in filament winding. This creates a uniform structure. In pultrusion, resin-impregnated carbon fibers are pulled through a die. Each process has its attributes. The choice of manufacturing process depends upon the specific application. Carbon fiber products are being used, from aerospace comp
