Study of the thermal behaviours of intumescent silicate materials
… Karl Fischer (KF), Mass Spectrometry (MS) and Cone Calorimetry (CC) techniques. Scanning Electron Microscopy (SEM) was also employed to study the sample morphologies. In this study, spectral data were analysed by multivariate Target Factor Analysis (TFA) to determine the relative evolution …

High Performance Materials Containing Nitrile Groups
… in the formation of heterocylic rings. TGA and cone calorimetry demonstrated that these networks have excellent thermo-oxidative stability. Further goals were to develop halogen-free, flame retardant monomers for improving the thermo-oxidative resistance of polystyrene and …

Nano-filled Epoxy: Mechanical and Fire Behavior and Modeling of Nanocomposite Columns Under Fire
… are measured. Flammability tests made by cone calorimetry are used to determine the Heat Release Rate, Mass Loss Rate, time to ignition, to Peak of heat Release rate and to flameout, and total smoke and heat released. A mathematical modeling of the stability of columns, made of the same …

Synthesis and Characterization of Phosphorus Containing Poly(arylene ether)s
… have improved fire resistance. Preliminary cone calorimetry measurements support this conclusion. In addition, the phosphine oxide group in the backbone was reduced to a phosphine and successfully converted to a phosphonium bromide ionomer. The resulting system was further chemically …

Experimental Evaluation of JP-8-Based Fire Resistant Fuels
… for both fuels. As a supplementary study, cone calorimetry testing was performed to determine effective heats of combustion. Results from experimentation demonstrated that the energy content of the FRF is not of primary importance to engine performance or flame resistance. All data, …

Synthesis and characterization of new polycarbonate material systems
… were determined by differential scanning calorimetry and thermogravimetric analysis. The glass transition temperature, as well as the residual char yield at elevated temperatures was found to increase with an increase in the phosphorus monomer content as measured by the two respective …

Polydimethylsiloxane Modification of Segmented Thermoplastic Polyurethanes and Polyureas
… fire resistance of the modified polyurethanes by cone calorimetry showed that the peak heat release rate of the 15wt% siloxane modified samples dropped 67wt%, compared with the polyurethane control. However, the peak heat release rate did not further change with increasing siloxane content. …

The Chemistry of Dimethacrylate-Styrene Networks and Development of Flame Retardant, Halogen-Free Fiber Reinforced Vinyl Ester Composites
… and dispersed into the vinyl ester matrix. Cone calorimetry showed reductions in the peak heat release rate comparable to the brominated resin.

Phase selective flame-retardant laminates
… by the superior performance of this laminate in cone calorimetry, which showed reduced peak of heat release rate (pHRR) and maximum average rate of heat emission (MARHE) values, indicating lower fire hazards. The third approach introduces protective interlayers – such as WHIPOX ceramic composite, …

Synthesis and Characterization of New Aryl Phosphine Oxide and Ketone Containing Poly(arylene Sulfide Sulfone)s
… with increasing sulfone content. TGA and micro cone calorimetry analyses showed that the semi-crystalline materials with high ketone content had much higher char yields and significantly lower heat release rate and total heat release, compared to the poly(phenylene sulfide sulfone) and …

Development of fire retardant timber treatments
… has been studied using microscale combustion calorimetry and cone calorimetry. Residue analysis has been carried out using scanning electron microscopy coupled with electron dispersive x-ray analysis. Existing fire retardant timber treatments were applied to timber specimens. All three …

Mg-Al Layered Double Hydroxide: A Potential Nanofiller and Flame-Retardant for Polyethylene
… methods, like limited oxygen index (LOI), cone-calorimetry and UL-94 vertical and horizontal burn tests. The cone-calorimetric investigation shows that the nanocomposites have significantly lower burning rate and heat released during combustion. With increasing concentration of LDH though …

Development of pyrolysis models of composite materials for fire safety engineering
… to establish a model that is able to predict cone calorimetry results. ThermaKin predicted the burning rate of PE/MA, as a good agreement between the experimental and simulated curves was achieved. Sensitivity analysis was performed to investigate the influence of the variation of the material …

Studying the Effect of Zinc 3-(Dibutylamino) Propionate (ZDAP) Additive on Fire Retardant, Mechanical, and Physical Characteristics of Epoxy-Amine Networks
<p>Epoxy-amine networks are useful as structural materials but are inherently flammable. To enhance the fire performance of epoxy-amine, Nazarenko research group developed zinc 3-(dibutylamino)propionate (ZDAP) as a fire-retardant additive. This zinc-salt-based fire retardant is an …
