Final answer:
Composite cables involve a center core made from different materials that form a composite material, which is used in various structural and functional applications, contrasting with coaxial cables that are specifically structured for audiovisual connections.
Step-by-step explanation:
According to the references, composite cables refer to cables that contain a center core and other materials which combine to form a multi-phase system. Composite cables are not to be confused with coaxial cables, which consist of two concentric conductors separated by insulation. Coaxial cables, as noted in Figure 9.18, are often used in applications such as cable TV and audiovisual connections. On the other side, composite materials include those made from two or more constituent materials with significantly different physical or chemical properties, such as a polymer-matrix composite, which consists of reinforcing fibers embedded in a polymer matrix. These composites can have uses in various contexts including other transport mediums like ships' superstructures, container vehicle bodies, and overhead power cables with a steel core for added strength.
