In this study the nut is manufactured from composite material and provides excellent tribology properties under heavy load conditions.
For this purpose the elastic element is imported into ANSYS database, are specified the materials of the elements, boundary conditions and loads.
On this test rig is studied the screw-nut assembly consisting of special bolt 15, nut 10 and washer 11 (there are several washers of various materials).

The paper analyzes the tensile behavior of some new biocomposite materials based on polypropylene reinforced with hemp shives for different volume fractions and sizes.
The analyzed materials are new materials based on renewable and recyclable resources and from this point of view these materials have a less harmful impact on the environment compared to the conventional composites.
By analyzing the tensile properties of polyproylene based biocomposites reinforced with hemp shives it can be observed in which way these materials could replace conventional materials in various fields of applications.
