                   Properties in the Combination of E-glass with Basalt, Jute or Flax Fibres



                           The hybrid composite of G2/J3/G2 exhibits the highest of specific impact peak

                   force, followed by G2/F3/G2 and G2/B3/G2 as shown in Figure 4.27. The similar trend
                   was observed previously on the specific peak force of quasi-static indentation (Figure

                   4.17).  The  combination  between  the  E-glass  with  jute  fibres  displays  the  ultimate

                   properties in comparison to the rest of the hybrid composites discussed in the present

                   study. However, in terms of specific impact energy, G2/F3/G2, G2/J3/G2 and G2/B3/G2
                                                                3
                   showing the value of 5.74, 4.73 and 4.31 J.dm /kg, respectively.
