J. Mar. Sci. Eng. 2020, 8, 26 13 of 28 Reinforced polymeric composites are considered an attractive alternative over conventional materials. This is particularly related to the superior corrosion resistance, high strength to weight ratio, and flexibility. The ability to tailor the mechanical properties controlling the type, quantity, and direction of the reinforcing material makes the composite tube an ideal candidate for applications in high-pressure conditions [20,21,35]. On the other hand, they must be weighed down in subsea applications (e.g., submerged pipes) and have a low resistance to abrasion. The used resins are both thermosetting and thermoplastics. Thermosets have found widespread use in offshore oil and gas, even if they typically exhibit more limitations than thermoplastics. Indeed, even if thermosets are relatively cheaper in terms of raw material and manufacturing, their shelf life is significantly limited. Furthermore, they offer higher mechanical properties and thermal stability than thermoplastics. On the other hand, the latter show better chemical resistance and lower water absorption, which makes them particularly suitable for offshore usages, combined with a notable recyclability [22]. A qualitative comparison between typical thermosetting and thermoplastic resins are reported in Tables 2 and 3.
