Fire Retardancy of Upholstered Furniture Composites Can Be Predicted Using Thermal Ignition Models

University of Canterbury Research Repository (University of Canterbury) · 2001

Key Findings

01The thermally thin theory provides a reasonably good comparison to measured ignition data for fabric-foam composites.
02The thermally thick theory is less accurate for predicting ignition compared to the thermally thin theory.
03The Flux Time Product (FTP) index appears to differentiate between melting and charring fabrics, with values below 1.0 for melting and above 1.0 for charring fabrics when a linear correlation is achieved.

Application

Design takeaway

Incorporate predictive thermal ignition models, particularly the thermally thin theory, into the material selection and design process for upholstered furniture to enhance fire safety.

How to apply

When designing upholstered furniture, use the principles of the thermally thin theory to estimate ignition times and critical heat fluxes for chosen fabric-foam combinations. Compare these predictions with experimental data or material specifications where available.

Project actions

Method & Evidence

AimCan the time-to-ignition and critical heat flux of upholstered furniture composites be accurately predicted using thermal ignition models?

MethodExperimental and Modelling

ProcedureFourteen fabric-foam composite combinations, representative of those used in New Zealand furniture, were tested using the ISO Ignitability Test (ISO5657). Time-to-ignition data were statistically analyzed. The thermally thin and thermally thick theories were applied to predict ignition characteristics, and results were compared to experimental data.
