What is it about?
Pineapple Leaf Fibers (PALF) is a lignocellulosic fibers extracted from pineapple leaf and used to replace synthethic fibers such as fiberglass in acoustic panels. This paper discover the engineering and acoustic properties of ultra lightweighted pineapple leaf fibers (PALF) - natural rubber latex binder (NR) composite to be used as acoustic sound absorber in the future.

Why is it important?
This study has investigated the acoustic performance of PALF board with and without inclusion natural rubber latex binder with thickness of 10 mm, 20 mm, and 30 mm. The composite reaches optimum density between range of 485 kg/m3 to 518 kg/m3. The summary of findings was composite with thicker samples have good sound absorption properties at mid and high range frequencies. Studies shown weak relationship between density, thickness and sound absorption performance in PALF-NR composite. P60NR40 board samples with 20 mm and P100NR0 with 20 mm thickness are the most suitable to be used as sound absorber panel for with and without binder composite since the NRC value of the composite are among the highest NRC values.
Perspectives
It was a great pleasure to work with all co-authors who help in the produce this paper in terms of theoretically and technically. I hope this article contributes benefit to the acoustic sound absorber panel manufacturer to produce more biodegradable, sustainable and safe working environment towards industrial workers and occupants.
