As a result, hybrid composites with SL sequence of G2/B3/G2, G2/J3/G2 and

G2/F3/G2 recorded the higher flexural properties than their IC sequences due to the
position of natural fibres located closely to the natural axis. Hence, the core of natural

fibres only resisting smaller load caused from bending instead of tension and
compression loadings are resisted by two layers of E-glass fibre. However, in the IC

sequences of [G/B]3G, [G/J]3G and [G/F]3G, the position of basalt, jute and flax are
located farther than SL sequence from neutral axis (y-distance) and resisting higher of

tension and compression loadings as mention in Equation 4.1. Hence, their flexural

properties are lower than SL specimens. This findings agreed with the previous studies
on the effect of stacking sequence of carbon/basalt reinforced epoxy [151], hybrid

composite laminates for load bearing structure [153], effects of interply hybridisation
on the damage resistance [156], mechanical behaviour of stacking sequence in kenaf

and banana fibre reinforced polyester [158] and hybrid composite laminates reinforced
with Kevlar/carbon/glass woven fabrics for ballistic impact testing [159].
