For the first time, Layer-by-layer (LbL) assemblies made with carbon nanofiber (CNFs) are shown to improve the fire performance of polyurethane foam. The (359 ± 36) nm thick four bilayer coating of polyethyleneimine/CNF (cationic layer) and poly(acrylic
It is desirable to replace Halon 1301, CF3Br, as the fire suppressant used in cargo bay fire suppression. Unfortunately, some candidate agents for replacing Halon 1301, in particular C2HF5, C3H2F3Br, C6F12O, were found to create greater pressure rise in an

In large-scale fires, the input of energy to burning materials occurs predominantly by radiative transfer. The in-depth absorption of radiant energy by a polymer influences its ignition time and burning rate. The present investigation examines two methods

Scientists are shifting their attention towards technology sustainability and sustainable materials, specifically in terms of energy and environmental impacts. The flame retardant community is also more concerned about these aspects. The recent banning of
Fire resistive materials (FRMs) serve a critical function in insulating (steel) structures to limit steel temperature rise during a fire exposure. This paper provides an overview of FRMs, focusing on the measurement of their thermophysical properties

Polyhedral oligomeric silsesquioxane (POSS) and cellulose were reacted in the ionic liquid, 1-ethyl-3-methylimidazolium acetate (EmiAc). Side reactions between the EmiAc and each reactant were prevalent, but use of water as the coagulating solvent produced

Estimation of the time available for escape (ASET) in the event of a fire is a principal component in fire hazard or risk assessment. Valid data on the yields of toxic smoke components from bench-scale apparatus is essential to accurate ASET calculations
This is the first reported use of Layer-by-Layer (LBL) assembly to fabricate thin film coatings on polyurethane foam, of incorporating carbon nanofibers (CNF) into LBL fabricated coatings, and of using LBL fabricated coatings to reduce the flammability of

Two different numerical simulation tools, Fire Dynamic Simulator FDS and ThermaKin, are investigated with respect to their capability to predict the mass loss rate of polymer materials exposed to different fires. For validation, gasification apparatus and

The versatility of polymeric materials, as demonstrated in such features as high strength, low weight, ease of processing, and capability to form into complex shapes, have led to their widespread industrial application in aircraft structures

The effects of the thermal properties of three flooring materials on the spread rate of polymer melt over the surface were studied using a model based on the Particle Finite Element Method (PFEM). The high thermal conductivity of steel keeps the steel

The capability of the Particle Finite Element Method (PFEM, developed by CIMNE) to model the complex fire behaviour of polymers in the UL 94 scenario was investigated. For validation, a series of four PC/ABS blends were chosen, which covered different UL
