| Abstract |
| Clay-polyethylene particulate composites were prepared using surface
modified kaolinite particles. The modification was achieved by a
thermal decomposition-hydration-redecomposition technique. Properties
such as density, porosity, tensile properties, abrasive wear and
dielectric properties of the composites containing 0.05-0.2 volume
fraction of surface modified kaolinite were measured and compared
to those containing untreated kaolinite. It was observed that composites
containing surface modified kaolinite showed improvements
in the above properties compared to the composites containing untreated
ones. The microstructural observations on the polished surface
-of the composites indicated a fairly uniform distribution of the partides
with less agglomeration in case of the surface modified kaolinite
composites as compared to those containing unmodified particles. |
