Investigation of energy efficient thermal insulating composites from hemp shives and starch

Abstract

This work presents the investigation results of physical-mechanical properties of fibrous hemp composite specimens produced from hemp shives and starch used as a binding material. For this purpose specimens with different amount of binding material, density and granulometric composition were used. Experimental results show that strength properties of composites linearly depend on the density of the material, as well as the density of hemp composites in all cases has the influence on change in thermal conductivity. During the research of mechanical properties it was determined that specimens with greater density and quantity of binding material had the greatest strength.
