Burning material behaviour in hypoxic environments: An experimental study examining a representative storage arrangement of acrylonitrile butadiene styrene, polyethylene bubble wrap, and cardboard layers as a composite system

Cone calorimeter and controlled atmosphere cone experiments were conducted on various samples. The intent of the tests was to examine behavior uniform composite samples in a range thicknesses, irradiances, oxygen concentrations. Single, layers acrylonitrile butadiene styrene (ABS) compared mix, comprising ABS with surface layer cardboard secondary polyethylene bubble wrap (intended represent potential storage arrangement). horizontal have been tested at irradiances 25 50 kW/m2 concentrations 20.95%, 17%, 15% significant variables. Results for arrangement indicated correlations, previously observed works others, such as relationships typically described between applied heat flux, ignitability, release rate effect introduction hypoxic conditions. However, results shown change significantly when arranged feature layers. A hypothesized cause behavioral change, namely soot char residual introduced from incomplete combustion layer, highlights further important variables that require consideration material testing under Such variables, specific behaviors sample orientation, must be sufficiently captured design methodologies systems reliant upon It is concluded capturing wider burning materials conditions will introduce resilience help optimize fire protection/prevention methods.
