MECHANICAL PROPERTIES OF BIOCOMPOSITE MATERIALS BASED ON EPOXYPOLYMER MATRIX

Abstract

The compressive strength limit of epoxy composite materials filled with wood flour powder or starch was determined. The effectiveness of the use of wood flour powder for the formation of epoxy composites was determined. The addition of wood flour powder provides higher compressive strength values of epoxy composites compared to the compressive strength of epoxy composites containing starch. In the case of using starch, the adhesive strength of epoxy composites increases compared to unfilled epoxy polymers. An increase in the adhesive strength of the components of the epoxy composite material occurs with the optimal content of starch in the epoxy polymer matrix. The optimal content of the filler is determined by the adhesive nature of the destruction of the adhesive connection of the epoxy composite material with the surface of the substrate.
