Cone calorimeter evaluation of reinforced hybrid wood

Abstract

Combustion performance for three types of wood–aluminum composites was investigated using cone calorimetry tests. The results revealed that time to ignition of the specimens was increased and more than 100 times after the lamination of 1.6-mm-thick aluminum alloy sheet on the surface (from 17 to 1990 s). And residual mass of the wood–aluminum composites was improved and almost quadrupled (from 21.795% to 81.664%). The peak heat release rate, average heat release rate, total heat release, and mean mass loss rate of wood–aluminum composites with 1.6-mm-thick aluminum alloy sheet on the surface were decreased to 70.18%, 48.71%, 24.27%, and 80.60%, respectively. However, yields of both CO and CO₂ are slightly improved with the increase in the thickness of aluminum alloy sheet because of incomplete combustion. The application of aluminum alloy sheets to the wood-based composites is an effective method for improving the combustion performance.
