Flexible composite drive shaft

A composite drive shaft comprising:

• a shaft portion extending along a longitudinal axis and defining a first end and a second end, the shaft portion having an outer surface;
• a web-based body extending along the longitudinal axis, the web-based body including a first composite layup end section disposed at the first end, a second composite layup end section disposed at the second end, a first spiral composite element extending between the first composite end section and the second composite layup end section, and a second spiral composite element extending between the first composite end section and the second composite layup end section, the first spiral composite element and the second composite spiral element being embedded into the first composite layup end section and the second composite layup end section, the first composite spiral element and the second composite spiral element being arranged in a bi-directional orientation relative to the longitudinal axis, the first spiral composite element and the second spiral composite element are arranged at pre-determined angles and possess a uni-directional fiber-reinforced polymer-matrix composite structure;
• wherein the first spiral composite element and the second spiral composite elements are applied to the outer surface and extend from the first composite layup end section to the second composite layup end section.
