The Effect of Filler Type on the Mechanical Properties of Composite Materials Based on Ultra-High-Molecular-Weight Polyethylene

The effect of the filler type (graphite nanoplates, organomodified montmorillonite, molybdenum disulphide, or shungite) on the deformation and strength properties of composite materials based on UHMWPE synthesized by in situ polymerization with a filler content of up to 0.06 vol fraction was studied. The significant effect of the filler type on the dependence of the tensile strength and the tensile elongation of the studied composites on the filler content was established. A significant difference between the tensile stress–strain curves for composites with different fillers was observed.
