dc.description.abstractIntraply hybrid composites have been fabricated by the
open leaky-mold method in order to examine the e ects of
hybridization on the mechanical performance of aramid/
polyethylene hybrid composite. The ¯exural properties,
interlaminar shear strength (ILSS), and impact properties
of these composites have been studied as a function of
aramid ®bre content and loading direction. Two di erent
stacking sequences ([0/0]4 and [0/90]4) were selected
for this study, and composites of four di erent aramid
®bre contents (100, 75, 50, and 0% by volume) have been
studied. In addition, scanning electron microscopy (SEM)
was used to examine the fracture surfaces of the intraply
hybrid composites. The ¯exural strength and modulus
increased with the volume fraction of aramid ®bre, and
negative deviations from the rule of mixture were observed
in all intraply laminates.When the load was applied in the
aramid direction, the highest ¯exural strength was
obtained. This is attributed to the fact that the ¯exural
strength mainly depends on whichever ®bre is present in
the longitudinal direction of the specimen. In contrast
with the ¯exural property results, intraply hybrid compo-
sites exhibited lower ILSS values than polyethylene-®bre
composites because of the di erence in the failure modes
in the ¯exural and ILSS tests. In addition, intraply hybrid
composites exhibited lower impact resistance than aramid
®bre composites because the level of maximum load had a
major e ect on the impact absorption energy. # 1998
