A
comparative study on industrial waste fillers affecting
mechanical properties of polymer-matrix composites |
|
This
paper investigates the mechanical properties of the various
inorganic filler-filled polymer composites. Sewage sludge ash
(SSA), fly ash (FA) and silicon carbide (SiC) micro-particles
were used as filler in the polyester resin. Composite samples
were prepared with various filler content of 5, 10, 15 and 20
wt%. The results indicated that the tensile and flexural
strength increased at the particle content of 5 wt% and then
followed a decreasing trend with further particle inclusion. The
tensile and flexural modulus values of the particulate polyester
composites were significantly enhanced compared with the
unfilled polyester composite. SEM micrograph results shown good
indication for dispersion of FA, SSA and SiC particles within
the polymer matrix. |
