“…Fatigue life simulations and testing are important considerations for composite materials used for marine applications, especially for highly functional and structural applications, such as offshore oil and gas drilling, marine propellers, and composite risers [92][93][94]. Several methods have been described to reduce the fatigue degradation of NFRP composites, including using coupling agents, nanoscale fillers, and epoxy elastomer blends and decreasing the variance of elastic properties between laminate ply interfaces [95][96][97].…”

Environmental emergency awareness has been gaining momentum in recent years in the composite manufacturing industry, with a new generation of composite materials minimizing their harmful environmental impacts by employing more sustainable manufacturing processes and, where possible, replacing synthetic materials with more sustainable bio-based materials, thus more efficiently using energy and material resources. In this context, natural fiber composites are proposed as appealing candidates to replace or reduce the use of synthetic fibers for reinforcing polymers in several industrial fields, such as the marine sector, where composite usage has been extensively studied in recent years. This review aims to present a thorough overview of the usage of natural fiber composites for marine applications, discussing the most relevant criteria required for applications where water exposure is expected. For this purpose, the review outlines the natural fibers and matrices used, analyzes the resultant composites’ mechanical properties, and presents the fiber treatments required before manufacturing, as well as the main manufacturing processes adopted for natural fiber composite production. The advantages and disadvantages of natural fibers compared to synthetic fibers are also presented, including economic and environmental credentials. Finally, a list of marine components with natural fiber reinforcements developed in recent years is reported.

“…However, introducing thick laminated structures, mainly in marine applications, created new challenges in NDE. Although there are a few studies in the literature on the inspection of thick laminates, most of them are limited to composites with a thickness of less than 10 mm or composites that contain near-surface defects [5,11,12]. Based on a recent review by Ibrahim [1], despite considerable efforts being made on several fronts, there remains the need to develop NDE methods for the accurate inspection and characterization of internal defects in thick composites.…”

Application of Acoustic Metamaterials in Pulse-Echo Ultrasonic Evaluation of Thick Hybrid Composite Laminates

Significant challenges exist in inspecting thick composite laminates for manufacturing defects and operational damage. This is due to acoustic attenuation and impedance mismatch at the interface between the different composite layers. An innovative concept for enhancing ultrasonic testing of such composite laminates is introduced in this study. The proposed solution exploits the ability of acoustic metamaterials to cloak virgin composite. Herein, we show that by incorporating carefully designed metamaterials in a pulse-echo ultrasonic testing setup, the position and size of a delamination in a thick hybrid composite laminate can be determined accurately.
