Abstract:
In many industrial applications, natural fiber reinforced composites are emerging as a
competitive substitute of composites based on synthetic fibers due to their numerous
advantages. However, real world applications of such composites require some secondary
operations in order to complete the assembly of the components or parts. This work focuses
on preparing hybrid composite made of glass and jute fiber along with epoxy composites
incorporated with nanofiller and investigating the machinability of those composites. Hand
lay-up technique was used to prepare the composites with five layers of fibers. Three types
of nanoparticle such as Al2O3, ZnO, and TiO2 of 3 wt.% were incorporated into the
composites. Machinability was assessed considering the delamination factor and surface
roughness. Analytical studies of machinability were conducted using minitab software. The
findings show that the addition of nanofillers considerably increases the machining
performance of the composite material. Comparing among three different nanofillers it was
found that the composite contains the ZnO nanoparticle provided the significant
improvement with least overall surface roughness and moderate delamination. On the
contrary, TiO2 incorporated composite material showed least delamination.
