Abstract:The formulation and processing of a brittle polyurethane foam containing triboluminescent powder additives is described. ). In each instance, the powders were mixed into the polyol component of the foam. When combined with the isocyanate component, the resulting foams had these powders incorporated into their cellular structure so as to induce a triboluminescent response upon crushing during impact testing.The triboluminescent response of foam specimens containing each of these powder additives was characteri… Show more
