| 抄録: | We used three-point bending tests to investigate the effects of elastomer lamination on the failure mode of bar-shaped products using isotactic polypropylene (PP). When a thermoplastic elastomer sheet was laminated on PP, which was prepared by double-shot injection molding, the specimen showed high mechanical toughness without signs of stress whitening. Although rubbery materials have low tensile moduli, their bulk moduli are comparable to those of plastics. Therefore, the laminated elastomer, located inside of the bending deformation, prohibits sharp bending angles during the deformation. Consequently, craze formation, which is the origin of stress whitening and leads to brittle fracture, hardly occurs. |
