From the results of n, the
following con clusions as been drawn:
1) The non-uniform distribution of c
e in the microstructure of the coconut shell reinforced
polyethylene composite is the major factor responsible
for the decrease in strength when compared with the
control sample having 0% coconut shell particles (See
2) As the-
eases, there was a corresponding decrease in porosity.
This property makes the composite suitable for the ap-
plication in the interior part of a motor car where materi-
als with good hydrophobic characteristic are required.
Similarly, the composite produced can be useful in other
interior parts of automobile where streng th is not consid-
ered a critical requirement, etc.
3) Coconut shell particles impprop-
ty of the polyethylene matrix composite. This property
is an added requirement for automobile interior .
