Summary
Building insulation polymers generally possess high ignitability, flammability, and toxic volatile emission in the event of a fire. Owing to the rapid increase of mega-scale or high-rise buildings in cosmopolitan cities, the massive application of polymer composites in numerous commercial materials and products has already been determined as the major cause of severe fire incidents including the Grenfell Tower fire incident in 2017 and Neo200. The burning of polymer composites involves multiple coupled and non-linear physical and chemical phenomena. While full-scale fire experiments may be conducted for the assessment of fire behaviour, they are extremely expensive, destructive, and produce many pollutants. A generalised predictive fire model is yet to be developed to simulate the all-inclusive phenomena and flame retardancy. Many developments have remained in the improvement of the gas-phase models involving the fluid interactions with the fire dynamics, turbulence, and radiation effects. To address this significant knowledge gap, reactive MD simulations (ReaxFF) were used to characterise the detailed pyrolytic process.
