摘要: The influence of microstructure on the fracture toughness, unnotched strength, Young's modulus and mechanism polybutadiene-reinforced poly(methylmethacrylate)s was investigated. increased with degree dispersion polybutadiene phase. A core-shell fine (≃ 1 μm) rubber particles gave highest toughness. Cavitation phase dominant toughening particulate morphologies, although additionally localized plastic yielding observed surface material a microstructure. lamellar-type morphology exhibited high toughness as result redirecting propagating crack to produce rough surface.
