Abstract

In 2022, Indonesia produce 3.2 million tons of pineapples. Besides the fruit, pineapple leaves can be used as composite materials. Combining pineapple leaf fibers with glass fibers offers a potential high-strength material. This study examines how different mass fractions of these fibers affect composite strength for car bumper alternatives. The highest tensile strength (116.40 MPa) was found in a specimen with 18.52 g Pineapple Leaf Fiber, 43.89 g Glass Fiber, 38.70 g Epoxy, and 18.14 g Hardener. However, the T-test showed no significant effect of mass fraction on tensile strength (0.123 > 0.05). For flextural strength, the highest value (136.45 MPa) was in a specimen with 11.25 g Pineapple Leaf Fiber, 26.67 g Glass Fiber, 23.52 g Epoxy, and 11.02 g Hardener, with no significant effect of mass fraction (0.784 > 0.05). The highest impact strength (57.61 kJ/m²) was found in a specimen with 9.36 g Pineapple Leaf Fiber, 22.18 g Glass Fiber, 19.56 g Epoxy, and 9.17 g Hardener. Unlike the other tests, the mass fraction significantly affected impact strength (0.001 < 0.05).
