摘要
<p>The line element has a two-layer, coaxial structure that is made of an inner flexible metal hose (11) that is wound from multiple strip layers. The line element is provided in the shape of non-uniform rational B-spline. The metal hose is wrapped by an external, rigid roller laminated tube (12). The rigid roller laminated tube is made of E-glass and pre-ceramic materials. The roller laminated roller tube is also made of knitted graphite fibers in combination with absorbent fibers. The tube is made of polyester resins, vinyl ester resins, epoxy resins or chemically bonded phosphate ceramics.</p>
