DEBONDING MICROPROCESSES AND INTERFACIAL STRENGTH IN PARTICLE-FILLED POLYMER MATERIALS

Griffith energy theory was developed for analysis of crack propagation along an interface in polymers filled with rigid spherical inclusions . A polydisperse structural model was used for stress-strain distribut ion analysis of composite materials. Experiments were performed on gla ss-bead filled polyethylene and polypropylene and epoxy resin. The dep endence of debonding stresses and angles on contraction stress, fricti on, particle diameter and material characteristics were analysed.
