Modeling of warping processes at cooling products from polyethylene with a filler having a negative coefficient of thermal expansion

Theoretical modeling process warping fan of polyethylene, filled with nanoparticles of lead zirconate titanate, Pb (Ti, Zr) O3, having a negative coefficient of thermal expansion carried out. It is shown that the volume filling about 30% manage to almost completely eliminate the effect of warping that occurs during cooling of this construction.
