The flammability of materials is a key component modern cladding fires. Vertical flame spread complex phenomenon which is, amongst others, function thermal inertia, ignition temperature, and heat release. recently published Cladding Materials Library contains the needed data to help engineers perform fire risk assessments on buildings. research has previously generally focused expensive time co...

A computational study is performed to investigate the effects of hydrogen addition on the fundamental characteristics of stretched methane/air premixed flame in an opposed flow configuration. The problem is of interest as a potential application to gas turbines and spark-ignition engines, where it has been anticipated that addition of a small amount of hydrogen will extend the lean flammability...

Standardized testing procedures and experimental studies in fire safety science specify repeat trials an effort to minimize the impact of statistical variation on presented results. Bench-scale flammability typically require a constant number – generally total three across all conditions. A series experiments was conducted quantify influence trial quantity Cone Calorimeter results; sets 100 ide...

Polyimide-graphene composites were synthesized by in-situ condensation polymerization and the thermal stability decomposition behavior of studied. Polyimides, because their aromatic backbone, are a class fire-retardant polymers. Their high char retention ≥50% at testing temperatures ≥600 °C makes them thermally stable The effect nanographene sheets on polyimide is presented in this paper. It sh...

Abstract Biological decomposition and wildfire are two predominant alternative processes that can mineralize organic C in forest litter. Currently, the relationships between fire still poorly understood. We provide an empirical test of hypothesized decoupling surface litter bed decomposability flammability, underlying traits trait spectra. employed a 41‐species set gymnosperms very broad evolut...
