As expected, the pure jute, J7 exhibits the lowest flexural properties, which is

about three times lower than the pure E-glass, G7. In the meantime, the incorporation
of E-glass fibre in E-glass/jute hybrid laminate contributes to the increasing flexural

strength and modulus about 77 % and 71 % compared to J7 as illustrated in Figure 4.9.
Hence, the creation of hybrid composite can compensate the weakness of its

constituents, specifically, the weakness of jute fibre will be compensated by the
superior properties of the E-glass. It is interesting to note that the incorporation of jute

fibre in E-glass/jute hybrid laminate could enhance the flexural properties compare to

the pure E-glass, G7. In other word, the presence of the jute fibre significantly
contributes in enhancing the overall flexural properties when embedded with the E-

glass reinforced epoxy. This finding is similar to the previous study conducted by
Rohit et al. [160] on the bending properties between the glass and jute laminates which

showed that the bending stress of jute laminates is higher than glass laminates for the
equal number of layers.

The results obtained for the E-glass/flax, E-glass and flax laminates are also

demonstrated the similar pattern. The pure flax, F7 laminate shows the lowest flexural
strength and modulus, while E-glass, G7 shows the highest. In this light, the flexural

strength of G7 is three times higher than F7, as depicted in Figure 4.9. The E-glass
laminate, G7 shows the highest flexural strength and modulus, followed by SL

sequence of G2/F3/G2, the IC sequence of [G/F]3G and finally, the pure flax, F7. The

incorporation of E-glass in producing the E-glass/flax hybrid composite compensates
the inferior properties of flax fibre. This observation would allow the flax fibre to be

potentially considered in constructing hybrid composite system as part of the
environmentally friendly of green technology development.
