interfacial bond. Consequently, the cracking at the initial stages has damaged the

matrix and the E-glass layers, before being transferred to the jute fibre. The presence
of E-glass on the next layer adjacent to the jute layer would slow down and blunt the

damage propagation, as shown in Figure 4.12. This observation is in line with the
observation in the previous study on jute/epoxy, jute/vinyl ester and jute/polyester,

where the failure mode starts with the tearing of the fibre, followed by matrix cracking
[46]. In addition, the jute laminate fractures easily occur in the bending mode,

compared to E-glass laminate, which typically debonds layer by layer in the mid span

of the specimen [160].
