In this study, the tensile properties and fatigue life of woven jute–glass hybrid–reinforced epoxy
composite were investigated experimentally. Various types of composites with different constituents
(jute, glass and hybrid composites) were prepared and tested according to ASTM(D3039 and D3479)
standards. Tests included: tensile test for determining the monotonic tensile strength and modulus,
and tension-tension fluctuating cyclic loading with a frequency of 5 Hz and stress ratio of 0.1 for
measuring the fatigue life and stiffness degradation. The results showed that jute fibre could partially
replace glass fibre within the polymeric hybrid composites towards the production of more ecofriendly
composites although there was a relative decline in composite’s tensile properties and fatigue
life. Incorporation of jute fibre within the hybrid composite reduced the fatigue sensitivity (stiffness
degradation) of the composite. A comparison between glass and hybrid composites indicates that
composite’s stiffness after 10 000 cycles reduced 21% (glass composites), 16% (30:70 of jute:glass
hybrid composites), and 12% (45:55 of jute:glass hybrid composites). Results suggested that the ecofriendly
and cheap natural fibres such as jute could be successfully hybridised with glass fibre for
structures subjected to cyclic loading.
