ABSTRACT
Weaving is probably the most ancient union technique among materials. The advanced techniques of structures with natural fiber woven ropes for the formation of original bridges from the Inca Empire which is a civil engineering example used up to now. Each year the construction of a bridge which is called Q’eswachaka coming from the origins of Inca in Peru is realized with ichu fibers (Stipa ichu). The ropes woven manually by means of torsion and braiding techniques and save a distance of approximately 29 meters on the River Apurimac. Large ropes which are those that will be placed at the base of the bridge, formed by 22 soguillas, twisted between each other and then braided up to 15–20 cm in diameter which can reach a resistance of 1800 kg. This article contributes to the investigation of techniques and structure building process which could be considered like the beginnings of bioengineering.
