Abstract: This paper considers the mass loss rate, specific extinction area, Heat Release Rate (HRR), Effective Heat Combustion (EHC), Total Heat Release (THR) and Ignitability Efficiency (IE) as the fire-hazard indices of Wood-Based Composites (WBCs). Fire-retardant dipped paper plays a major role in the flame resistance of WBCs. An optimized cone calorimeter is developed, and the flame-retardant properties of plain and modified WBCs are assessed. The HRR curves reach the wave crest at a high rate with no distinct peaks in the period of 81 s to 320 s. EHC histograms are slightly low, where their increasing tendencies are not apparent within the time range of 110 s-320 s. However, the relatively small THR of modified Medium-Density Fiberboard (MDF) indicates that it emits less heat with a minor fire risk. We conclude that IE follows the order: MDF with dipped paper ⪅ plywood with dipped paper ⪅chipboard with dipped paper, with the chipboard showing the largest combustion risk.
