This study used a hand layup process to create tri-layer hybrid composites composed of snake grass fiber (SGF) and jute fiber (JF). Two types of hybrid composites were investigated: jute/snake grass/jute (J/S/J) and snake grass/jute/snake grass (S/J/S). The fabricated composites were subjected to mechanical characterization and water absorption studies to verify their compatibility for various applications. The outcome revealed that the J/S/J hybrid sample shows the highest tensile and flexural strength at 68.46 and 78.62 MPa, respectively. This is due to stacking the maximum-strength JF as an exterior layer in the hybrid J/S/J sample. Meanwhile, the S/J/S composite shows a very high impact strength value of 4.45 kJ/mm2 due to the placement of SGF at the outermost layer. It leads to absorbing more impact energy at sudden load applications. Water absorption studies revealed that the S/J/S composite absorbed more moisture than the J/S/J composite. Furthermore, the S/J/S composite exhibited greater biodegradability than the J/S/J composite based on soil burial experiments. From this study, it can be concluded that the J/S/J composite is suitable for structural applications because it has higher tensile and flexural qualities. In contrast, the S/J/S composite can be employed under damping conditions because it has better impact strength.

In the recent decades, natural fiber reinforced composite (NFRC) plays a vital role in most of the engineering applications including automobile and structural. The demand for novel natural fiber increasing steeply in recent times. Current research work aimed to develop hybrid sansevieria trifasciata fiber (HSTF)/polyester composite, and researchers combined untreated sansevieria trifasciata fibers (USTFs) with NaOH treated sisal fibers (NSTFs) and combined them with a polyester matrix. The reinforced effect of HSTFs was shown to be superior to that of NSTFs. It has the tensile strength of 48.47 MPa, the flexural strength of 69.17 MPa, and the impact strength of 16.34 kJ/m2. The thermal behaviour of the composite increased because of chemical treatment and hybrid composition. Polyester/HSTFs show superior mechanical properties compared to other developed samples.
