“…For each composition, the HRR vs. time curves are characterised by an increase in HRR up to a maximum value PHRR (presented in Figure ), followed by a drop after this peak. The appearance of organoclay contributes to the reduction in PHRR as 1% of organoclay (in sample S1) can lower the PHRR to 80% compared to the baseline sample S0, and further reduction was observed at higher concentration of organoclay (in S3 and S5) which shows a good agreement with literature . Compared to the baseline sample S0, samples containing organoclay also improved the flame retardancy of the laminates in terms of THR (Figure ).…”

SUMMARY Organoclay glass fibre reinforced polymer (GFRP) nanocomposites are fabricated using the vacuum assisted resin transfer moulding. The unsaturated polyester resin is prepared with and without organoclay involving mechanical mixing, sonication, dilution solvent and heat treatment. Three levels of organophilic clay content are added, and its influences on the fire performance of composite samples are investigated. A novel numerical procedure combining pyrolysis analysis of the organoclay‐composites and the fire dynamic simulation of the combustion process are developed to validate the thermal responses obtained from the cone calorimetry experiments. Kinetic parameters obtained from the TGA tests and pyrolysis analyses are used as inputs for the models measuring the fire growth index and total heat release. To account for multilayer composite structure and organoclay distribution, three numerical models are proposed including composite (CPS), component (CPN) and CPN‐layer models. While CPS model assumes the homogeneity of the composite, later models consider multilayer effects with uniform (CPN model) or concentrated (CPN‐layer model) distribution of organoclay. Numerical results are compared with experimental ones in terms of total heat release, fire growth index. Finally, the fire resistance and total smoke release of the polyester/glass composites with the addition of organoclay will be evaluated taking into account influences of the fabrication processes.

“…In particular, polyhedral oligomeric silsesquioxanes (POSS) have gained attention due to the fact that they possess both organic and inorganic character and can be functionalised with a various number of reactive moieties. Previous research findings prove that addition of POSS to epoxy resin blends dramatically reduces water uptake [16], improves resistance to thermo-oxygen degradation [17], thermal stability and fire retardancy [18,19] and also such materials show remarkable resistance to atomic oxygen, which is critical for extraterrestrial exposures [20].…”
