Tensile Modulus of Film Stacked Palm Fibers-LDPE Sheet Composites
MetadataShow full item record
Palm fiber-LDPE composites were prepared by a film-stacking methodstudying the effects of fibers content, their length, processing temperatureand alkaline treatment on tensile modulus and modulus efficiency factor. Itwas found that up to 5 wt.% and processing temperature to 160°C inaddition to alkaline treatment improved the tensile modulus and modulusefficiency factor to a certain limit due to an enhancement in load carryingand interfacial adhesion, also it was obvious that long fibers play a positiverole in load transfer; improving the tensile modulus and its efficiency factordue to effective load transfer. Ductility was decreased due to the brittlebehavior of the fibers.
