Flexural test was done on woven jute/glass reinforced epoxy. The presence of

glass layer at the outer surface of sandwich jute/glass reacts as a strong skin and
contributed to increase the overall bending properties in comparison to jute composite

[34].

The effect of hybridisation on flexural loading between jute and glass

toughened epoxy was investigated. Result showed that the hybrid composite positively

influenced the flexural properties in comparison with its parental constituent [89].

Flexural test was done on jute fibre-reinforced polypropylene (PP) composite

with fibre weight fraction was set at 0.5. Result showed that the tested specimen
recorded the flexural strength and modulus of 56 MPa and 1.5 GPa, respectively [51].

Effect of stacking sequence and hybridisation between basalt/aramid were
investigated on four points bending test. Results showed that the sandwich-like

sequence (seven basalt layers as a core and three layers of aramid as a skin) exhibited

superior flexural properties in comparison with intercalation sequence. However, post
impact flexural strength of the tested specimen with intercalation sequence showed the

most favourable degradation pattern with small delaminations observed between
dissimilar layers instead of major delaminations occurred in the tension side at the

basalt and aramid interfaces [90].

Flexural properties between pure jute and hybrid specimen of jute/glass were
compared on flexural strength and modulus. The presence of glass fibre in jute/glass

hybrid composite contributed in increasing flexural strength and modulus from 115.61
to 366.38 MPa and 18.70 to 23.40 GPa, respectively [60].

Atiqah et al. [83] studied the hybrid composite of kenaf/glass toughened

unsaturated polyester resin on the flexural loading. It is remarkable that the flexural
modulus was found to be increasing with the decrease of glass loading up to certain

condition and drastically drop down after the volume fraction of kenaf fibre exceed
the optimum level. As found in tensile, kenaf/glass with volume fraction of 15/15
