| 中文摘要 | to study the brittle-ductile transition (bdt) of polypropylene (pp)/ethylene-propylene-diene monomer (epdm) blends induced by size, temperature, and time, the toughness of the pp/epdm blends was investigated over wide ranges of epdm content, temperature, and strain rate. the toughness of the blends was determined from the tensile fracture energy of the side-edge notched samples. the concept of interparticle distance (id) was introduced into this study to probe the size effect on the bdt of pp/epdm blends, whereas the effect of time corresponded to that of strain rate. the bdt induced by size, temperature, and time was observed in the fracture energy versus id, temperature, and strain rate. the critical bdt temperatures for various epdm contents at different initial strain rates were obtained from these transitions. the critical interparticle distance (idc) increased nonlinearly with increasing temperature, and when the initial strain rate was lower, the idc was larger. moreover, the variation of the reciprocal of the initial strain rate with the reciprocal of temperature followed different straight lines for various epdm contents. these straight lines were with the same slope. |
