“…S7b) display four broad peaks. The peak at 750 cm -1 , which stems from C-O-P vibrations, 20 vanishes in the PNC2 800 spectrum, probably due to very low carbon content in this sample. Nevertheless, stretching vibrations corresponding to phosphate groups, ν(P-O-P/ PO4 -3 ), can be observed at 926 cm -1 , along with a peak at 1240 cm -1 which stems from a P=O stretching vibration.…”

“…Melamine poly(zincphosphate) and its aluminium and magnesium analogues were studied as synergistic agents associated with AlPi in glass fibre-reinforced PA66. The mechanism of action in flame retardancy was reported by Naik et al [118]. The authors disclosed the possible degradation pathway, relying on the chemical species they identified in both condensed and gas phases.…”

Future materials in the field of thermoplastics require a lower impact on the environment. Actual thermoplastic materials also require "greener" additives for thermal and fire resistance profile. In this work, some of the recent solutions for halogen-free flame retardants were discussed in the context of viable routes with economical and industrial relevance. The fire retardant mechanism was discussed in order to imagine new solutions for future additives. Some of the main (inorganic, organic or hybrid) flame retardants can be used as common platform for the next classes of thermoplastic composites (synthetic, natural, or bio-based). The new generation of flame retardants (based on the emerging solutions) will have to surpass two major barriers: the cost effectiveness and the need for high concentration (which usually affects other properties).

“…At present, comprehensive nomenclature of flame retardants include halogen-based [24,25] and phosphorusbased [26][27][28][29][30] substances. Recent achievements in flame retardant development are represented by organometallic [31], e.g. ferrocene [18,[32][33][34], and organosilicon (e.g.…”

In the present work we have studied the thermal stability, flammability, and fume evolution of epoxy matrix composites with different types and amounts of hardeners, fillers, plasticizers, and fire retardants. It is shown that chemical composition of fillers has little effect on the flammability of epoxy composites when the content of mineral fillers is less than 45 % by mass. Smoke formation decreases linearly with increase of the filling degree. It is shown that to obtain low-combustible materials the oxygen index should exceed 31 %. It was found that the optimal concentration of industrial brominated fire retardants is 8-10 % by mass. To reduce the flammability of epoxy composites, additive brominated fire retardants in the form of a solution in N,N-dimethyl-2,4,6-tribromoaniline have been proposed. The high efficiency of acetyl-and α-hydroxyethyl ferrocene as a smoke suppressor of epoxy composites is shown.
