Cavitation during tensile drawing of semicrystalline polymers (in English)

Polimery 2011, No 9, 627


DOI: dx.doi.org/10.14314/polimery.2011.627


Summary

The article presents the state of knowledge on the phenomenon of cavitation observed during uniaxial stretching of semicrystalline polymers. Cavitation occurs when the stress at which the amorphous phase breaks is lower than the stress initiating plastic deformation of crystals. The text presents the process of plastic deformation and conditions in which polymers cavitate. Special attention is devoted to plastic deformation and cavitation in polyethylene, polypropylene and polyamide with regard to recent results of own works.


Key words: semicrystalline polymers, plastic deformation, cavitation, polyethylene, polypropylene
