N2 - This investigation aims to study the influence of various environments, such as groundwater, seawater, mineral water and sub-zero, on reinforced polyester/S-glass/sisal composites with nano clay (NC). Composites with a configuration of S-glass/sisal/sisal/S-glass (GSSG) with different wt% of NC, such as 0, 2, 4, and 6, were manufactured using the hand lay-up method. For 6 days, the composites were conditioned in different environments like seawater, mineral water, groundwater at room temperature, and sub-zero environments at −17°C. The influence of these environments on the tensile and flexural properties of manufactured composites was studied. Composites with 4% NC displayed higher tensile strength, while composites with 2% NC exhibited maximum flexural strength for all the environments. It was perceived that the weight gain was maximum in seawater (0.1857 g) and minimum in mineral water (0.06 g) and sub-zero (0.101 g) conditions for 6% NC condition. Tensile and flexural strengths were reduced by 27% and 24% when samples were submerged in seawater compared to other environments. TEM images for 4 wt% of NC and 6 wt% of NC were studied for dispersions of NC in Polyester, and the effect of NC mixing with polyester was understood for the hybrid polymer composites. Highlights: A novel hybrid composites were fabricated using a double stirring process. The ultra-sonication led to uniform distribution of nanoparticles. The mechanical properties and the effect of environments on these properties are studied. SEM images revealed the aging due to various environments. The hybrid composites can store mineral water and the sub-zero environment.
