Effect of Moisture on the Resistance of Sansevieria Cylindrica-Reinforced Vinyl Ester Composites

The research is intended to determine the absorption behavior of a newly fabricated, sansevieria cylindrica-reinforced vinyl ester composite (SCVEC) under a different immersion medium. For this purpose, seawater, distilled water, and groundwater was taken. The samples of untreated and sodium hydroxide (NaOH)-treated SCVEC with varying fiber content and fiber length was subjected to water absorption studies. The diffusion coefficient, permeability coefficient, and sorption coefficient were determined to study the kinetics of water molecules penetrating the SCVEC. The results show that SCVEC can resist seawater effectively compared to other medium. This is because of the salt molecule, which disables the secure transport of water molecules into the composite. NaOH-treated composites showed better results compared to the untreated composites irrespective of immersion medium. Scanning electron microscopic studies reveal the water absorption mechanism of SCVEC materials.
