Globally, glass fiber composites have a wide application in industries such as automotive, marine, aerospace and many more. However, their use is not environmentally friendly due to their lack of degradability. Through this study, we search to demonstrate new, replaceable composites made from pure coir and coir-jute mixed composites. We will showcase their mechanical properties in parallel by comparing them with the standard mechanical properties of S-glass and E-glass composites. So, three types of mechanical testing were con-ducted: hardness (ASTM E10), impact energy (ASTM D256), and wear resistance (ASTM G99). The results were compared with typical E glass and S glass composites. Samples were made with 100% coir fiber reinforced with polyester and coir and jute fiber mixture (50:50) reinforced with polyester. The 100% coir and fiber composite showed 17.62% higher hardness values than E glass and 56.83% higher hardness values than S glass. The coir and jute fiber mixture composite showed 10.06% higher hardness values than E glass and 46.75% higher hardness values than S glass. However, both samples showed low impact energy absorption and higher percentages of wear resistance compared to E and S glass. The higher wear in the coir-jute hybrid highlights the need for additional optimization. These findings under-line the potential of coir-based composites as eco-friendly materials with re-markable mechanical properties. Improvements in wear resistance can be accomplished by introducing suitable filler materials and changing their compositions. The good conclusions from this research illustrate the potential of coir fiber-reinforced composites in numerous industries, contributing to the development of environmentally sustainable and resilient engineered materials.
