Abstract: | Mechanical characteristics of polymerization filled composite materials based on ultrahigh-molecular-weight polyethylene and
fine aluminum particles are studied. The prepared composites preserve their ability for high plastic deformations even when
the volume filler content is φ = 0.57. For the tensile drawing of the composite material with randomly distributed particles,
an equation describing the dependence of breaking stress on the volume filler content is derived. For the model of the composite
with regularly ordered particles, the Nielsen equation is the approximation of the equation proposed in this work for a material
with randomly distributed particles. |
