4.8.3 The Effect of Reinforcement Selection on the Quasi-Static Indentation
Properties in the Combination of E-glass with Basalt, Jute or Flax Fibres
The effect of reinforcement selection between E-glass/basalt, E-glass/jute and
E-glass/flax were compared based on specific energy absorption and the specific peak
force, as depicted in Figure 4.17. The tested specimen of G2/J3/G2 exhibits the highest
specific energy absorption compared to the G2/B3/G2 and G2/F3/G2. In this regard,
again the density of the hybrid laminates significantly influenced on the specific
properties of the materials being investigated. E-glass/jute recorded the lowest density
3
value of 1.43 kg/dm in comparison with E-glass/basalt and E-glass/flax of 1.85 and
3
1.56 kg/dm , respectively.
The similar trend was observed on the specific peak force with hybrid laminate
of E-glass/jute leads the highest property than those of E-glass/basalt and E-glass/flax.
Even though single fibre of basalt exhibits a higher peak force than jute and flax
laminates, the overall properties of hybrid laminates show unexpected response in
which the combination between E-glass and jute fibres recorded the superior properties
