Summary: Engineered wood products including particle boards have huge global demand requiring enhancement for end users’ benefits. This study produced particle boards using Bamban Grass Stem (BGS) and Unsaturated Polyester Resin (UPR). The BGS and UPR were fabricated into a Particle board utilizing hand tools for manual methods of preparation of raw materials from harvesting to pulverizing and drying. The board density is 0.8 g/cc with five mix design ratios of 46:54, 48:52, 50:50, 52:48, and 54:46 of UPR to BGS manually mixed and cured for three days. Test results following the Philippine National Standard (PNS) showed satisfactory values on Internal Bond (IB) with 54:46 design obtaining 1.47 MPa against 0.28 MPa of PNS, 52:48 design with Relative Density (RD) of 1.96% compared to PNS maximum value of 10%, 52:48 design of most minor Thickness Swelling (TS) of 1.68% against PNS 12% maximum value, and Water Absorption with 50:50 at 24.07% water absorption against 40% limit. The minimum values of PNS for Modulus of Rupture were not met with 5.82 MPa versus 10.5 MPa. Similarly, only the 54:46 design passed the maximum value allowed in the Moisture Content Test with 12.2% compared to 14%. However, the result of the Technological University of the Philippines Evaluation Instrument comprising 42 respondents shows the particle board is “Very Acceptable” with a mean rating of 4.26. This metrics concludes that the BGS and UPR at the mentioned mix- design ratios can create a particle board with room for improvements to increase its mechanical properties and acceptability.

Engineered wood products including particle boards have huge global demand requiring
enhancement for end users’ benefits. This study produced particle boards using Bamban
Grass Stem (BGS) and Unsaturated Polyester Resin (UPR). The BGS and UPR were
fabricated into a Particle board utilizing hand tools for manual methods of preparation of
raw materials from harvesting to pulverizing and drying. The board density is 0.8 g/cc with
five mix design ratios of 46:54, 48:52, 50:50, 52:48, and 54:46 of UPR to BGS manually
mixed and cured for three days. Test results following the Philippine National Standard
(PNS) showed satisfactory values on Internal Bond (IB) with 54:46 design obtaining 1.47
MPa against 0.28 MPa of PNS, 52:48 design with Relative Density (RD) of 1.96%
compared to PNS maximum value of 10%, 52:48 design of most minor Thickness Swelling
(TS) of 1.68% against PNS 12% maximum value, and Water Absorption with 50:50 at
24.07% water absorption against 40% limit. The minimum values of PNS for Modulus of
Rupture were not met with 5.82 MPa versus 10.5 MPa. Similarly, only the 54:46 design
passed the maximum value allowed in the Moisture Content Test with 12.2% compared to
14%. However, the result of the Technological University of the Philippines Evaluation
Instrument comprising 42 respondents shows the particle board is “Very Acceptable” with
a mean rating of 4.26. This metrics concludes that the BGS and UPR at the mentioned mix-
design ratios can create a particle board with room for improvements to increase its mechanical properties and acceptability.
