FRACTURE TOUHGNESS OF CR TYPES OF POLYPROPYLENE IMPACT COPOLYMER

Popis výsledku v původním jazyce

Effect of controlled rheology on properties of impact polypropylene copolymer is described in this contribution. As the native material was chosen the impact copolymer of MFR = 4g/10min. Two series of samples (A and B) were prepared using two different technological modes of CR process. SENB and CT specimens were prepared from these materials. The instrumented Charpy tests were performed using SENB (single edged-notched bend) specimens in quasi-dynamic mode. Tests were done at laboratory temperature (23centigrade degrees) and at low temperature (-20 centigrade degrees). Toughness of material was evaluated for stable and unstable fractures. The toughness of stable material fractures was evaluated on the basis of crack resistance curves (JR-integral). The toughness of unstable material fractures was evaluated using Sumpter and Turner integral formula (J(STId)-integral). CT (compact tension) specimens were tested in tensile mode at laboratory temperature (23 centigrade degrees). Only sta
