Abstract
Discarded florescent tubes and graphite rods obtained from dumped primary
cells have been processed to obtain glass and graphite particles. 80 µm glass
and graphite particles were used as reinforcements in epoxy resin, LY 556
cured with HY 931 hardener to produce epoxy resin hybrid composites. The
morphology, mechanical properties, thermal stability and wear resistance
characteristics of the epoxy resin glass/graphite hybrid composites were
studied. The thermogravimetric analyser TGA 701 was used to examine the
thermal stability of the epoxy resin glass particle/graphite composites. Addi‐
tion of graphite and glass particles enhanced the strength, thermal stability
and wear resistance of the epoxy resin. However, tensile strain and impact
energy absorption of the epoxy resin hybrid composites started declining at 6
wt% of glass particle addition. The increase in wear rate of the composites
with an increment in applied loads is attributable to increase in the normal
reaction between the examined sample surfaces and the emery paper. Fur‐
thermore, the increase in wear resistance with an increment in wt% of glass
particle additions is attributable to good interfacial adhesion between matrix
and the fillers. The textural and appearance differences between the scanning
electron micrographs of the control and epoxy resin hybrid composites is
attributable to the presence of new phases due to exothermic and cross link‐
ing reaction between the matrix and the fillers. Hence, new vital engineering
composites peculiar to automobile, aerospace and building industries have
been produced.
