Particleboard can be made from a variety of natural fibers, although wood remains the most
important raw material due to its relative quantity and year-round availability. However,
rising demand for forest resources for a variety of purposes has resulted in a wood supply
crisis. As a result, alternative raw materials are required. The purpose of this research is to
look into the effects of utilizing natural fibers on the physical and mechanical properties of
particleboard. Using three mix designs with ratios of 97:3, 95:5, and 93:7 raw material –
binder with a target density of 1.0 kg/cc. The particleboards were tested for Physical
Properties such as Thickness Swelling and Water Absorption, as well as Mechanical
Properties such as Internal Bonding, Modulus of Rupture, and Face Screw Holding. All of
the tests were performed in accordance with the requirements of the Philippines National
Standard (PNS) 230:1989 for type-200 high-density board. Based on the results, it was
found out that among all the mix design ratios specifically in Thickness Swelling
Determination Test, the two (2) mix designs did meet the required standards with 7.90%
and 18.31% while in Water Absorption Determination Test, all the mix design did not meet
the required standard. In Internal Bond Test, the mix design one (1) and two (2) with 11.32
kg/cm2
and 10.81 kg/cm2
, respectively, passed the required standard. The modulus of
rupture test result showed that all the mix designs did not meet the required standard. And
the face screw holding test, only the mix design two (2) achieved values of 55.27% which
met the minimum PNS standard of 50%.
