Defining Composite Tube Manufacturing
At its core, composite tube manufacturing is the process of combining reinforcing materials (fibers) with a matrix material (resin) to create a tubular product with enhanced properties. Unlike traditional metallic tubes, composite tubes are engineered materials where the properties can be tailored by adjusting the fiber type, orientation, and resin composition. This allows for the creation of tubes with specific characteristics such as high tensile strength, corrosion resistance, and thermal stability.
