Abstract

Being biodegradable and user-friendly, the unique composite formed of natural fibres has amazing potential for weight reduction in materials while also lowering the cost of materials due to its low cost. However, natural fibres has a lower strength than polyester resin 100 percent, which is a disadvantage. Many research investigations have been conducted on two-hybrid composites that include natural and synthetic fibres. A fresh investigation of the mechanical behaviour of pineapple leaves reinforced by polyester resin (PLPR) composites was reported in the current work. Five eco-friendly ratios of natural and synthetic materials were produced utilising the mixing composites, which were constructed using the hand lay-up technique. These composites have the following weight ratios: 20% pineapple leaf and 80% polyester resin (20PL80PR), 40% pineapple leaf and 60% polyester resin (40PL60PR), 50% pineapple leaf and 50% polyester resin (50PL50PR), 60% pineapple leaf and 40% polyester resin (60PL40PR), and 80% pineapple leaf and 20% polyester resin (80PL20PR). Tensile, flexural, and impact tests were used to investigate the mechanical properties of the pictures of the powdered pineapple leaf obtained using a stereo microscope. Statistics were used to assess the data that had been collected. The mechanical behaviour of the PLPR composites according to the five ratios is seen through numerical calculations and graphical examples. The mechanical behaviour of PLPR composites will have an impact on the various ratios. The results showed that the composite with 60% pineapple leaf had better mechanical behaviour than the other composites due to the synergistic effect of reinforcements
