hence will damage the fibre. On the other hand, [G/F]3G created minor ply splitting as

depicted in Figure 4.30(b). These kind of failure images possible to describe the
weakness of [G/B]3G and [G/F]3G in resisting impact loading in comparison with

G2/B3/G2 and G2/F3/G2. However, E-glass/flax recorded the highest specific energy
absorption than the other hybrid composites. The advantages of this combination can

be clearly seen with minor surface cracks or damages as illustrated in Figure 4.31. As
a result, it can be concluded that the formation of hybrid composite between E-glass

and flax fibres with epoxy resin shows a good surficial adhesion and it would

potentially to be used in composite industry.
