Special Issue Information

Dear Colleagues,

Fiber-reinforced composites have been employed in marine applications for decades, beginning with the manufacturing of ships and vessels. At present, composites are employed in all areas of the marine sector and for a variety of components and structures, including hulls, bearings, propellers, hatch covers, railings, vessels of all types, valves, and other subsea structures. Indeed, the replacement of metals and wood with fiber-reinforced polymer (FRP) composite materials in components and structures offers known advantages, e.g., enhanced corrosion resistance, a lighter weight, no or reduced maintenance, durability, and design flexibility.

On the other hand, the growing of the market for composites has brought about several challenges concerning the development of innovative FRP materials, the establishment of new design guidelines, the development of efficient manufacturing, and development of tools for computational analysis.

The Special Issue aims to highlight recent developments in the area of fiber-reinforced composites in marine applications, including, but not limited, to the following:

  • fiber-reinforced composite manufacturing;
  • marine composite sandwich structures;
  • marine renewable energy devices;
  • composites in oil and gas applications;
  • underwater constructions;
  • underwater repair;
  • light marine structures;
  • durability of composites in a marine environment; and
  • life cycle assessment and disposal of marine composites.

As guest editors, it is our pleasure to invite you to make a valuable contribution to this Special Issue, which aims to present new results from this rapidly expanding field.

Keywords

  • advanced composite materials
  • hybrid composite materials
  • GFRP, CFRP and AFRP manufacturing
  • light marine structures
  • marine renewable energy
  • underwater construction
  • repair

Currently, the properties of composites have been harnessed on pipelines in the marine offshore industry. In this study, marine bonded composite hose (MBCH) is presented. It is aimed at understanding the stress/strain distribution on marine bonded hoses using local design pressure under burst and collapse cases. This study also investigates composite material modelling, hose modelling, liner wrinkling, helical spring deformation, and two MBCH models—with and without ovalisation. The ovalized model is considered the simplified model in this research. A mesh study was carried out on meshing the hose layers. In this study, local design pressure was considered and not operational pressure. This finite element model was adopted to predict the deformation and mechanical response behaviour of MBCH. From this study, composites could be considered to improve conventional marine hoses. The study findings include identification of buckled sections on the hose and stressed zones on the helix reinforcement. Highly reinforced hose ends are recommended in ends of the MBCH as they had maximum stress and strain values. Full article

Composite materials are used in various industries such as marine, aircraft, automotive, etc. In marine applications, composites are exposed to seawater, which can affect their mechanical properties due to moisture absorption. This work focuses on the durability of composite materials under the short-term effect of seawater ageing. The specimens were prepared from glass fiber/epoxy using a hand lap-up method and stitched in the z-direction with Kevlar fiber. The specimens were submerged in seawater for 24 and 35 days. A significant decrease in maximum load was found as specimen immersion time in seawater increased. The seawater ageing also affected fracture toughness with a reduction of 30% for 24 days immersion and 55% for 35 days. The ageing also caused the swelling of composites due to moisture absorption, which increased the weight of the specimens. Compared to the dry specimens, the weight of the specimen for 24 days increases to 5.2% and 7.89% for 35 days’ seawater ageing. The analysis also showed that due to seawater ageing, the de-bonding rate increased as the number of days increased. Full article

This study aimed to investigate the feasibility of using polypropylene fiber-cement-stabilized coastal clay as base-course material or foundation material for city sustainable development by assessing its mechanical performance. The influence of the number of freeze–thaw cycles and curing ages on the mechanical properties of ordinary cemented clay (OCC) and polypropylene fiber-cemented clay (PCC) was investigated by using unconfined compressive test. The experimental results show that the addition of fiber with 1% content can increase the strength as well as the ductility of cemented clay by 12.5% and 15.6%, respectively. The strength of PCC and OCC at 22d age was 1.5 times than at 7d age. Under differently timed freeze–thaw cycles, the mechanical performance of PCC is improved, and, better than that, OCC improves by 11.8% in strength, 16.5% in strain and by 5% in degree of damage, indicating that fiber can improve the freeze–thaw resistance of cemented clay. The frost resistance of PCC and OCC increases with the increase in curing age. Finally, the variation of strength of OCC was explained through the change of micro-structure while the strength enhancing mechanism of polypropylene fiber for cemented clay was also revealed.
