Conclusions
-
1.
The viscosity, elasticity, and stress relaxation of a melt of composites of HDPE containing chalk, FG, and a mixture of the two were studied. The deformational-strength and relaxation characteristics of composites with a different previous history were investigated.
-
2.
There are significant differences in the rheological behavior of melts of composites containing a coarsely disperse filler in shear and uniaxial extension.
-
3.
There is a correlation between the relaxation and strength characteristics of composites based on HDPE on one hand and the relaxation and rheological properties of their melts on the other hand. An increase in the viscosity and elasticity of a melt of the composites with a change in the concentration or nature of the filler results in an increase in the strength of the oriented composite.
-
4.
Addition of a disperse filler to a fibrous filler decreases the viscosity of the composites in shear and extension while not significantly affecting their strength.
-
5.
Doping of HDPE decreases the viscosity of its composites and improves the strength characteristics of shaped and oriented material.
