Abstract
Reinforcement of polymers with particles to enhance their mechanical
properties for various applications cannot be over emphasized. Hence, the microstructure
and mechanical behaviour of polyester resin matrix composites reinforced with pineapple
leaf particles was studied in order to develop an engineering material for industrial
applications. Pineapple leaf particles treated and untreated with NaOH were separately
blended with unsaturated polyester resin. 1 g of catalyst and 0.5 g of accelerator were
added to the mixture to achieve a homogeneous interfacial interaction. The composites
were made by mould casting and their microstructure and mechanical properties were
evaluated. The NaOH treated pineapple leaf particles reinforced composite exhibited the
highest tensile strength of 98.73 MPa at 15 wt. % and impact energy of 20.73 J at 20 wt.
%. Microstructure showed a fairly uniform distribution of the pineapple leaf particles in
the polyester resin matrix coupled with the strong interfacial bonding of the filler and
matrix as the major factors responsible for the enhancement of the tensile strength and
impact energy of the composites.
