The Effect of Rubber Particle Size and Polymer Properties on Impact Strength and Fracture Behavior of Rubber/Polymer Composites

고무입자의 크기와 폴리머의 물성이 고무/폴리머 복합재료의 충격강도 및 파괴거동에 미치는 영향

The toughening mechanism and fracture behavior of rubber/polymer composites were investigated with respect to two factors; (1) the composition ratio of polymers(PPO and PS which have a different chain flexibility) and (ii) the rubber particle size in PPO/PS blend system Izod impact test and fractographic observation of the fracture surface using scanning electron microscope were conducted, Finite element analysis were carried out to gain understanding of plastic deformation(shear yielding and crazing) of these materials.
