the laminates? Is it reasonable to conclude that the hybrid composite is inferior by

characterising its behaviour in bending mode only? From open literatures, there are
lack of studies on the effect of materials selection in designing the composite structures

to resist tension and bending loadings. Also, the application of natural fibre hybrid
composite in resisting quasi-static indentation loading is less reported.

On the dynamic site, the performances of natural fibre hybrid composites are

less reported. From author point of view, an extensive investigation is needed to
promote and discover the capability of natural fibres for structural application. In

addition, the rate of loading applied is very substantial to configure the ultimate
capability of natural fibre hybrid composites. Furthermore, it is rarely found the

characterisation of natural fibre hybrid using SHPB in resisting dynamic loading. High
strain rates response of pure and natural fibre hybrid composites as well as the effect

of hybridisation are less reported on the dynamic behaviour.

1.3 Research Objectives

This study aims to investigate the static and dynamic behaviours of natural

fibre hybrid composites. The details of this study are as follows:

(a) To study the effects of stacking sequence and hybrid configuration on static

and dynamic behaviour of E-glass/basalt, E-glass/jute and E-glass/flax
composite laminates.

(b) To evaluate the effect of hybridisation on static and dynamic behaviour of E-
glass/basalt, E-glass/jute and E-glass/flax composite laminates and compare to

those of pure composite laminates.

(c) To investigate the effect of strain rate on dynamic response of hybrid and pure
composite laminates.
