In the paper, the mechanical properties of the materials based on graphene С62Н20 and polyethylene (-СН2-СН2-)n have been investigated by using semiempirical PM3 method, and the visual models of molecules have been constructed (-СН2-СН2-)n. The calculated values of mechanical parameters show that these materials possess a high elasticity and strength. The orbital energies, potentials of ionization, full energies of electrons, strengths, etc. for given material have been calculated. Opportunity of using these light materials in engineering industry for making of superstrong protective thin coating on car bumpers have been considered. The necessary minimal thickness of protective coating during two cars collision with given mass and speed has been calculated that bumpers do not damage.
