RESEARCHES CONCERNING THE STRENGTH CHARACTERISTICS OF THE COMPOSITE MATERIALS WHICH USE WASTES FROM LEATHER INDUSTRY

The present paper presents original results regarding the experimentation of a new composite material, made of elastomeric matrix (rubber) with proteic reinforcement. The composite material is realised in five structural variants, depending on the concentration of fibrous reinforcement obtained from wastes from leather. There are presented in particular, results regarding the mechanical characteristics of each variant of composite material, directly related to the concentration in material of fibres from proteic wastes. It highlights the correlation between the mechanical characteristics of composite material, both in the initial version (primary), and in artificially aged material version through experiments to accelerated requests.
