Advancements in Composite Materials: Development and Experimental Analysis of Banana and Bamboo Fiber Reinforced Polyester Composites

The development of bamboo and banana‐reinforced polyester composite was the subject of the investigation. For a hybrid polymer composite, two cellulosic fibers are used as reinforcement because of their affordability, availability, and environmentally beneficial waste disposal. Furthermore, the highly fibrous and hydrophilic fibers are collected locally, which enables them to create a strong bond with the polyester polymeric matrix in the form of particle fibers. Thus, the purpose of this study is to examine the application of banana and bamboo fiber in composite construction. Composites were made by hand lay‐up method using a waste natural resource mixture of banana and bamboo fiber for reinforcement. Samples that have been separated and developed are evaluated for their thermal and mechanical characteristics. All processes are showed in the graphical abstract in Figure 1. Using the hybrid composite to its advantage, three samples were created and examined. According to the data, the composite with the excess bamboo fiber exhibits greater performance than the other two samples. In conclusion, when combined with bamboo fiber in small amounts, banana fiber’s adequate elasticity can improve the qualities. The sample exhibits favorable proper‐ ties in the bend, impact, and thermal conductivity tests.
