Experimental research conducted by RMUTT’s faculty member and researcher turns leftover palm fibers into industrial-grade soundproofing boards. Highly durable and flexible, palm fibers have been used in the production of furniture. Considering these properties, Kittichart Homaswin, the researcher, saw potentials of palm fibers as an effective soundproofing material.

The process involves heat pressing leftover palm fibers at high pressure, setting the density at 200-400kg/cubic meters, temperature of 150 degrees Celsius, pressure of 25-30kg/cubic meter, thickness of 12.5mm. and 20mm., for 8 minutes. Then, apply 5 to 7 per cent pMDI adhesive.

After sound testing, the final product has better soundproofing property than other products available in the market. The palm fiber boards can absorb up to 29.42 per cent of the noise, at the density of 400kg/cubic meter, th

ickness of 20mm, while other soundproofing boards in the market can absorb up to 26.46 per cent. In terms of sound frequency, the palm fiber boards can absorb medium to high frequencies (500Hz-2,000Hz).

According to the results, the palm fiber boards with the density of 400kg/cubic meter and 5 per cent and 7 per cent adhesive meet the United States Library of Congress’ strength and mechanical properties of soft boards. The 5 per cent adhesive is suitable for industrial production.
