This publication presents the experimental and numerical methods to model the devolatilization process of a glass‐fibre‐reinforced polyester/balsa‐cored sandwich material on small scale. The fundamental modelling of the source term in pyrolysis‐based fire simulations requires as input data the thermochemical properties of solid fuel and the kinetic parameters of the devolatilization process. First, the thermal decomposition of both elements composing the sandwich structure was studied by thermogravimetry coupled with gas analysis, in air and pure nitrogen atmospheres at several heating rates, in order to define a comprehensive multi‐step reaction pathway. A differential equation system is defined to model these decomposition processes. The kinetic parameters were then estimated by solving the system of equations by an inverse problem. Second, the fire behaviour of each element was studied separately and then combined in the sandwich structure on the cone calorimeter. In addition, numerical simulations with Fire Dynamics Simulator were performed to gradually assess the ability of the model(s) to reproduce each element composing the sandwich structure. Numerical and experimental results are compared and then discussed. Overall, the model provides a good agreement with the experimental data and encourages to model higher scales.

“…Another approach is therefore to assess the characteristic depth of thermal diffusion δ t (t).I t i s d e fi n e d b y δ t (t) > A √ α s t where α denotes the thermal diffusivity (m.s −2 ). A is a constant (between 1.13 and 4) which evolves from one author to another [Dusimberre (1998), Dembsey & Jacoby (2000)]. This equation is only valid for simple radiative thermal ignition and does not consider heat loss by emissionq ′′ re which depends on the surface emissivity.…”

“…Lightweight materials, such as glass-reinforced polyester (GRP), are necessary for aircraft and marine interior panels. Their unique characteristics [1][2][3] of interest are: high strength-to-weight ratio; durability and resistance to the marine environment; ease of maintenance and repair; toughness, particularly at low temperatures; and low thermal conductivity compared with metals.…”

A series of experiments were conducted to study the fundamental fire and thermal properties of glass-reinforced polyester (GRP) panel material. Both bench-scale and room-scale tests were performed. The GRP was characterized using TGA, DSC, and cone calorimetry. Several predicting models, such as heat release index model, FO-categories model, and minimum energy release rate for flashover model, were used to classify the GRP and forecast the flashover time based on the test results in the cone calorimeter at 50 kW/m 2 irradiance. Four experiments were conducted in GRP panels lined ISO 9705 room with a small wooden crib as an ignition source. Flashover time and panel burning time was compared with model study and thermal analysis results.
