The methods of deposition of nanofibers on a rotating drum and a stationary plate, as well as analysis of mechanical properties of the nanofibers from both collectors, are proposed in this article. The deposition of nanofibers on collectors is crucial, as it is the successful development of nanofibers with various types of collectors, as well as the evaluation and demonstration of their strength and other mechanical properties. The most popular method for producing continuous nanofibers is electro spinning, which involves jetting polymer solutions in high electric fields to produce continuous nanofibers with diameters ranging from 200 to 600 nm. These results were compared using ANSYS, and the material behavior of biaxial nanofibers collected from the spinning collector was identified. The rotating drum collector’s spinning speed causes the fibers to stretch, resulting in alignment and a decrease in diameter. The rotating drum collector adds force to the strong shear and elongation forces that arrange the chains and align the lamellae in the fiber axis direction during the electro spinning process. As a result, the nanofibers on the rotating drum are aligned uniaxial. It indicates that by altering the collector design, the alignment and mechanical properties of nanofibers can be improved. The results showed that the nanofibers collected from the spinning drum were more consistently aligned (biaxial arrangement) than those obtained from the stationary plate and had Young’s modulus of composite 5.01 GPa and 4.4 GPa respectively, ~9% more strength than the nanofibers collected from flat plate
