摘要

The objective of this study was to perform a multifaceted analysis of the behavior of natural fibers geotextiles from Typha domingensis, Eleocharis sp., and Syagrus coronata under environmental stressors over 120 days. Twenty-four fibers samples were selected, each 7 cm length, under field exposure, from the mentioned species. The majority of these samples underwent treatment with waterproofing acrylic styrene resin at two concentrations: 0.324 mg/mL (0.0324%) for a single layer and 0.648 mg/mL (0.0648%) for a double layer, while control samples remained untreated. Fracture analysis was conducted using digital processing of scanning electron microscopy images, revealing diferent degrees of resistance to degradation influenced by different treatments and exposure times. Typha domingensis fibers treated with the higher concentration resin (0.0648%) showed a remarkable reduction in cracking, presenting an improvement of 350.6% in durability compared to untreated fibers. Eleocharis sp. fibers treated with a double layer of resin (0.0648%) demonstrated better resistance to degradation, with a fracture reduction of 75.36% compared to untreated fibers and a notable improvement over the single-layer treatment (0.0324%). No statistically significant difference between the single-layer and double-layer resin treatments was observed in Syagrus coronata fibers, which nevertheless displayed inherent resistance to degradation even without treatment. Typha domingensis fibers exhibited better physical performance, probably due to their favorable morphological and structural characteristics and intrinsic composition. These findings highlight the critical role of additives and protective treatments in enhancing the durability and mechanical strength of geotextiles, while underscoring the distinct responses of different fiber species to chemical additives.
