Advancements in Fibre-Reinforced Polymer Laminates: Mechanical Property Requirements for Marine Applications

Abstract

Fibre-reinforced polymer (FRP) laminates play a vital role in marine applications, thanks to their exceptional strength-to-weight ratio, corrosion resistance, and long-lasting durability in challenging environments. This paper explores the progress made in FRP laminates, focusing on their mechanical characteristics, production methods, and effectiveness in marine environments. This study investigates the tensile, flexural, and compressive strength of FRP. This is vital for the retention of structural integrity in dynamic sea environments as well as the maintenance of fatigue and impact resistance. New manufacturing processes, including cryogenic drilling, vacuum-assisted resin transfer moulding (VARTM), and hybrid FRP-metal laminates, enhance mechanical performance and lower processing flaws. Evaluation of the material durability within saline and moist conditions emphasizes protective coatings and the insulation layer against galvanic corrosion. FRP laminates possess improved performance under marine conditions as compared to the conventional materials. This implies suitability for the manufacture of vessels, offshore structures, and underwater reinforcing. The following paper is a major contribution in reporting the complex evolution of FRP laminates to promote durability and high performance in marine engineering applications.
