ABSTRACT = {Oil palm ash (OPA) is an agro-industry waste and it has disposable
problems. In the present study, an effort was made for value addition to OPA by
incorporating it as a micro-filler in different concentration (0, 10, 20, 30, 40, and
50%) and sizes (100, 200, and 300 mesh size particles) in the epoxy matrix.
Prepared micro OPA was having a crystallinity index of 65.4%, high inorganic
elements, and smooth surface morphology. Fabricated composites had higher
void content as compared to neat epoxy matrix. Mechanical properties of
fabricated composites had a maximum value at 30% loading of 300 mesh-size
filler due to its low void content and size as compared to filler of 100 and 200
mesh size. Further increase in the concentration of OPA filler after 30 wt% of
loading leads to the agglomeration of OPA microparticles and thereby resulted in
the reduction of mechanical characteristics such as tensile strength, tensile
modulus, flexural strength and flexural modulus of the composites. However,
elongation at break decreased with increase in filler content at all percentage.
Thermal stability and char residue percentage of composite increased with the
concentration of filler at all percentage. Surface morphology of composite
showed that OPA incorporation lead towards its roughness and cracks were
originated from the site of OPA embedded in the epoxy matrix. The 300 meshsize
particles were having the best effect on composite as compared to 100 and
200 mesh-size filler.},
