“…The background work and procedure of the GA optimisation for a generic hydrofoil had been presented earlier by Herath et al [40,41]. Based on the past literature [42][43][44] and the previous work on hydrofoil [45,46], a real-coded GA combined with an elitist strategy was applied for better efficiency and faster convergence. Two elites were passed to the next generation, and half the number of the remaining sequences were produced using crossover and the other half by mutation until the final convergence is reached in GA.…”

Fibre reinforced composites materials offer a pathway to produce passive shape adaptive smart marine propellers, which have improved performance characteristics over traditional metallic alloys. Automated fibre placement (AFP) technology can provide a leap forward in cyber-physical automated manufacturing, which is essential for the implementation and operation of smart factories in the marine propeller industry towards Industry 4.0 readiness. In this paper, a comprehensive structural health monitoring routine was performed on an AFP full-scale composite hydrofoil to gain confidence in its dynamic and structural performances through a number of active and passive sensors. The hydrofoil was subjected to constant amplitude flexural fatigue loading in a purpose-built test rig for 105 cycles. The hydrofoil was embedded with distributed optical fibre sensors, traditional electrical strain gauges and linear variable displacement transducers. Both microelectromechanical system and piezoelectric accelerometers were used to conduct experimental modal analyses to observe changes in the modal response of the hydrofoil at regular intervals throughout the fatigue program. The hydrofoils modal response, as well as the stiffness measured using both displacements and strains, remained unchanged over the fatigue loading regime demonstrating the structural integrity of the hydrofoil. The optical fibre sensors endured the fatigue test cycles showing their robustness under fatigue loads. Furthermore, the sensing systems demonstrated the potential of being utilised as a useful maintenance tool combining their adaptability with automated manufacturing during manufacturing through integration within the hydrofoil, a structural test framework for performance measurement, data acquisition and analytics for visualisation, and the prospect of decision making for maintenance requirement during any onset in structural performance.

“…Distributed sensors are suitable to monitor strain fields over a section or the whole structure [34,35]. Accordingly, they are beneficial for the health monitoring of large composite structures, including hydrofoils, where strains need to be monitored at multiple locations or sections [36,37].…”

“…One example is the use of carbon fiber prepreg to manufacture a five-blade propeller with a diameter of 250 mm, using the compression molding process [12]. The introduction of Automated Fiber Placement (AFP) is another promising alternative, and this has been shown to result in optimal mechanical properties of composite hydrofoils [13,14]. Studies on thermoplastic composite blades are also possible using this process.…”

“…The use of automated fiber placement (AFP) is increasing, as it offers the possibility to produce very complex shapes with tight process control [ 1 ]. Initially developed for high performance aerospace applications, the capability for efficient manufacture of complex structures can also be applied to marine components such as hydrofoils [ 2 ], propellers [ 3 ], and tidal turbine blades [ 4 ]. These structures tend to be thicker than aerospace composites, so through-thickness properties are more critical.…”

Automated fiber placement (AFP), once limited to aerospace, is gaining acceptance and offers great potential for marine structures. This paper describes the influence of manufacturing defects, gaps, and overlaps, on the out-of-plane properties of carbon/epoxy composites manufactured by AFP. Apparent interlaminar shear strength measured by short beam shear tests was not affected by the presence of defects. However, the defects do affect delamination propagation. Under Mode I (tension) loading a small crack arrest effect is noted, resulting in higher apparent fracture energies, particularly for specimens manufactured using a caul plate. Under Mode II (in-plane shear) loading there is a more significant effect with increased fracture resistance, as stable propagation for specimens with small gaps changes to arrest with unstable propagation for larger gaps.
