Abstract
Offshore platforms and other marine structures have long been anchored with steel cables, however, synthetic fiber cables have recently become a very advantageous alternative for the oil and gas industry. The smaller mass and smaller submerged area required, with equivalent mechanical resistance, presented decisive characteristics of the synthetic compounds in front of the steel. Throughout this recent update of offshore anchorage, studies on the mechanical performance of synthetic materials under real conditions become increasingly important to understand the behavior of this new alternative. The objective of this work is to investigate the influence of the hydrolysis phenomenon on the mechanical strength of polyamide fibers. Two specific temperatures (70 ° C and 80 ° C) were defined for the immersion of filaments in salt water. After the immersion periods, the rupture stress results were obtained. It was observed during the study that a new variable denominated here like "rest time" directly influences the value of the rupture tension increasing it proportionally to the time immersed. This fact can change ways of making fiber and open up a new field of study.
