Optimization of the mode of thermal treatment of biocomposites filled with coffee grounds

Abstract

An increase the duration of heat treatment leads to an increase in compressive strength, since treatment in a thermal field at a temperature of 150 °C ensures the melting of the biopolymer binder, resulting in sufficient wetting of the surface of the filler particles. This causes an increase in the packing density of the components of the biocomposite material and the formation of a significantly larger number of physical and chemical bonds.
