Abstract: | Composite materials made of ultrahigh-molecular-weight polyethylene (UHMWPE) and boron have been synthesized using polymerization filling (polymerization in situ), varying the boron content in a wide range from, 10 to 75 vol %. The behavior of synthesized composites during deformation under compression depending on the degree of filling has been studied, and it has been determined that composites with a boron content of about 45 vol % have the maximum value for Young’s modulus, and increases in stress values at offset yield strength under compression is observed up to the filler content of 52 vol %. Based on the analysis of the stress–strain curves under compression, it can be asserted that, even at high degrees of filling, UHMWPE–boron composites retain plastic deformation. |
