The study, Effects of Pineapple Leaves Fiber as Reinforcement to Royal Poinciana Pod-
Isocyanate Board, aims to improve the physical and mechanical test results of the

previous research, Development of Royal Poinciana Pod-Isocyanate Board, while
utilizing pineapple leaves wastes as reinforcement. The last study failed to meet PNS
Specification for type 150 on Water Absorption, Thickness Swelling, Modulus of
Rupture, Face Screw Holding Test and Internal Bond Test. The mix designs of this study
are basing from the two (2) mix designs that had the best results of the previous research,
97:3 and 95:5, and reinforcing both designs with 5%, 10% and 15% of Pineapple Leaves
Fiber. The project underwent significant processes such as raw material collection, fiber
extraction, drying, shredding, sieving, mixing, molding, hot pressing, curing, testing and
evaluation to determine the acceptability of the board. Based on the physical test results,
only one mix design met the PNS for Water Absorption which is 27.82% while its
Thickness Swelling is 21.55% which did not pass the PNS as well as all the other mix
designs. For mechanical test results, none from the mix designs met the PNS for Modulus
of Rupture while all mix designs met the PNS for Face Screw Holding Test and Internal
Bond Test with best results of 77.12kg/cm2 and 8.33kg/cm2 accordingly. With an
average mean of 4.19 from 30 respondents, the project was rated descriptively as “Very
Acceptable.” Overall, the results from all mix designs showed improvement compared to
the previous study.
