Bending Deformation Behavior of Eggshell and Eggshell–Polymer Composites

Deformation behavior of the composite “eggshell–polymer plomb” was examined under bending. Hen eggs were taken as a biological material for experiments. It shown that viscoelastic polymer coating does not change type deformation composite, given eggshell continued to be brittle despite its mechanical characteristics varying widely solid. Joint “polymer plomb–eggshell” never cracked bending and hence exhibited high cohesion strength stresses applied in these seems “eggshell—polymer could substitute “tooth enamel–polymer elaboration novel restorative materials dentistry, namely, examination their properties, including cohesive strength.
