Features of deformation behavior of particulate-filled composites based on polyethylene and rubber particles at elevated temperatures
The deformation behavior of composites based on high density polyethylene and crosslinked rubber particles at elevated temperatures was investigated. Tests at temperatures from 20 to 60 0C with increasing filler concentration the transition from ductile deformation to brittle fracture and then to macrohomogeneous deformation. In the temperature range from 75 to 90° C the transition from stretch material to form the neck to the deformation with the formation of extended necks and then to macrohomogeneous tension was found. Stretching with the formation of extended necks implemented with an elastic filler content of 26 to 56 vol.%.
