| Abstract Scope |
In this paper, we investigate ultra-high-molecular-weight-polyethylene (UHWMPE) doped with carbon nanoinclusions. Both carbon black (CB) and nano graphite (NG) inclusions are considered. Micro-computed tomography (\mu CT) and scanning electron microscopy (SEM) studies show that for the considered carbon inclusion types, with weight fractions up to 10% wt., the nanoinclusions arrange as layers of carbon-containing mixture around UHMWPE granules. The thickness of the layers depends on the type of inclusions, volume fraction, and the manufacturing process.
To investigate how the effective material properties of the composite depend on the thickness of the carbon-containing layer, we use mesoscale numerical simulations combined with analytical micromechanical modeling approaches. Representative volume elements of the nanocomposite are generated and used for mechanical and thermal analysis by finite element method. Parametric studies are conducted for the overall thermal conductivity and elastic moduli of carbon/UHMWPE composites manufactured by compression molding and equal channel angular extrusion procedures. The simulation results are compared with the experimental measurements. |
