Epoxy resin mechanical properties in composition with copper (I) oxide particles, encapsulated by polylactide with variable thickness

Abstract

The required functional and mechanical properties are necessary for design the polymer compositions with dispersed fillers. The mechanical properties of such polymer composition can be changed by encapsulated filler particles shell thickness varying. The paper shows that the presence of polylactide polymer shell and its thickness on the surfaces of copper (I) oxide particles significantly affect the strength of polymer composite material based on ED-20 epoxy resin. That is due to the interaction between encapsulated particles and the matrix polymer, in contrast to noncapsulated particles. In addition, a change in particle size due to increasing shell thickness also affects the strength properties of the composition. It is shown that the elastic modulus of the filled epoxy composite does not depend on the shell thickness on the particle surfaces.
