ABSTRACT:
A composite tubing includes: an outer tubing which is prepared by seaming along a lengthwise direction two lateral sides of a lengthwise-extending strip made from a deformable material, the lateral sides being disposed opposite to each other in a transverse direction relative to the lengthwise direction, and being superimposed on each other so as to form a tubular body and a seamed ridge, the tubular body including a force-bearing-side half and a ridge-side half cooperating with each other to define a compressible tubular chamber, the seamed ridge extending from the ridge-side half radially and lengthwise; and a fiber-based rope disposed to extend lengthwise in the compressible tubular chamber, and being of a dimension such that, when the force-bearing-side half is pressed and deformed, the fiber-based rope is shiftable against the ridge-side half so as to vest the tubular body with an increased strength while preserving the padding effect of the force-bearing-side half.
