compressive stress of 19.8, 21.5 and 24.6 % was noticed when the applied strain rate
-1
increases from 700 to 2214 s for G2/B3/G2, G2/J3/G2 and G2/F3/G2, respectively.

5.2 Recommendations

Even though there were much work have been conducted for the static and
dynamic mechanical properties characterisation of hybrid and pure composites, from

author point of view, future works are still needed for improvement to gain better

understanding and responses, especially for the hybrid composites consist of natural
fibres. Based on this concern, the following works are suggested to be carried out in

the future to further discover the behaviours and analysis of the static and dynamic
characteristics of polymeric composite materials:

1. Mechanical properties characterisation such as tensile, flexural, quasi-static
indentation, low velocity and SHPB tests are suggested to perform at elevated

temperature instead of at room temperature to examine the effect of temperature
differences on the properties of natural fibre-based hybrid composite laminates.

2. As far as environmental issue is concerned, physical properties characterisation
such as water uptake and moisture absorption tests are suggested to be carried

out. Furthermore, natural fibres are hydrophilic in nature and is the main

drawback when dealing with natural resources.

3. Design of experiment (DOE) is suggested to be included in the future research
to get the correlation between factors or parameters involved and help

researchers in identifying the significant contributors. As a result, it will help
researchers in predicting the desired outcomes and eliminate the occurrence of

trial and error in doing experimental test and it will save time and money.

4. For dynamic test, the author would like to suggest for dynamic tension using the

same apparatus used in dynamic compression. Dynamic tensile strength and
