Evaluate fire behavior GRP panel

Abstract

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.

“…The TTFO model can also be derived using all the 52 materials (TTFO-52). Similar to Equations (5) and (12), the functions for the division of Groups 1-4 and the further category division within Group 1 are given by Equations (13) and (14), respectively:…”

“…TTFO-52 uses functions (Equations (13) and (14)) and critical values (Table VIII) for group divisions that are quite different from those for TTFO-28 (Equations (5) and (12) and Table III). However, as seen in Table IX, the classification accuracy of TTFO-52 is quite similar to that in Table VI for TTFO-28, with just an improvement of 22% for FO-category 2.…”

“…With similar model inputs, Hansen and Hovde developed a model to discriminate which category a material belongs to [3]. These models are simple but practical and widely applied for material assessment [10][11][12][13]. However, none of these models has a high level of precision for classifying materials for all the four categories.…”
