A Study of the Fire Performance of Timber-Walled Compartments
The work focuses on the construction of a partial compartment with 3-ply veneer laminates and analysing the fire performance of the laminated natural composite structure. Instead of the typical L-shaped slots, the compartment was built with traditional joints that were constructed using Ados F2, a high-performance general-purpose contact adhesive composed of polychloroprene. The significant aspect of this study is the fire-performance of the sample at a larger scale with certain variabilities from the ASTM E1354 standard, to suit the current requirements. The compartment was constructed with a vertical front wall of size 300 mm × 300 mm and two parallel side walls each having size of 300 mm × 70 mm. The fire performance of the structure was evaluated by performing a modified cone calorimeter test where the cone was held in a vertical position. The tests were conducted under 35, 50 and 69 kW/m2 heat flux values. The results show a comparatively low peak heat release rate, which can be directly attributed to the distance of the burner and the sample, along with significant temperature gradient along the surface of the main wall and an average burn time of 93 s and 84.3 s for 50 and 69 kW/m2 heat flux values, respectively, with no burning experienced for the flux value of 35 kW/m2. The study indicates that the fire properties of plywood, although having limiting criteria in building structures where fire is a key issue, can be used for benchmarking the future studies to introduce fire safety in plywood structures.
