“…In this reference epoxy resin system, with the application of ammonium polyphosphate (APP) as additive flame retardant, the V-0 could be reached only at 5 mass% P-content, while DOPO proved to be incompatible with the pentaerythritol-based epoxy component as even at 4 mass% of P-loading, the UL-94 classification remained HB. Optimization and Scale-Up of the Synthesis of TEDAP in ReactIR-Apparatus Based on the comparison of LOI and UL-94 results (Table III) and previous flame-retardancy results on TEDAP, [17][18][19] optimization and scale-up of the synthesis of TEDAP was carried out.…”

“…The authors also aimed at finding an alternative route to produce the phosphorus-containing reactive amine curing agents previously synthesized, 17 in particular N,N 0 ,N 00 -tris(2-aminoethyl)phosphoric triamide (TEDAP), which found its use not only as flame retardant, 18,19 but also as base material for pH-reversible supramolecular hydrogels 20 and for preparation and stabilization of gold nano-and microcrystals. 21 …”

The flame-retardant efficacy of phosphorus-containing reactive amine hardeners for epoxy resins is well-known; however their synthesis often applies hazardous, objectionable reagents. The aim of this work is to develop an effective synthesis method for the preparation of P-containing amines, which can act as flame-retardant crosslinking agent in epoxy resins. The syntheses and testing of an aliphatic and two aromatic amines are described: curing properties, glass transition temperature, thermal stability, and flameretardant performance of the amines are studied. On the basis of these results, the scaling-up and the optimization of the synthesis of the phosphorus-containing aliphatic amine hardener in ReactIR TM in situ FTIR apparatus is discussed.

In this review article, different approaches of enhancing flame retardancy of polymeric composite material and their effect on different composite properties are analysed critically. The mechanisms of fire spreading on composite materials are also discussed. Flame retardancy of polymeric composite material can be enhanced either by enhancing the fire performance of constituents of composite i.e. matrices and reinforcing agents or by providing a protective flame retardant (FR) coating around the composite material. Fire performance of reinforcing material is improved by treating with FR-chemicals while the fire performance of polymer matrices can be improved by incorporating micro and nano FR-fillers or by introducing FR-compound into polymer backbone. The flammability of micro and nano filler added polymeric composites and newly developed polymer derivatives and their effect on composite properties like mechanical, thermal have been discussed. However, the development of flame retardant polymer composite is still at nascent stage and for further development, it is necessary to work on the development of non-health hazardous, environment friendly flame retarding agents which will be able to enhance the fire performance of composite materials at very low concentration levels.

“…All blends consisting of EP, CE and phosphorus-containing flame retardant reached the V-0 UL-94 classification and exhibited intensive intumescent charring and increased residual mass. Although the carbon fibre reinforcement plies hinder the solid phase intumescent mechanism of the phosphorus flame retardant [22], as the reinforcement itself is inflammable under the conditions of the flame retardancy tests, the composite specimens showed even better flame retardant properties than the polymer matrices alone. In composite specimens 40 mass% of PT-30 alone was sufficient to reach the V-0 UL-94 rate.…”

Abstract. Cyanate ester/epoxy resin (CE/EP) carbon fibre reinforced composites consisting of diglycidyl ether of bisphenol A (DGEBA) and novolac type cyanate ester (CE) were prepared and reactively flame retarded using epoxy functional adduct of DGEBA and 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO). Effect of cyanate ester and flame retardant (FR) ratio was determined on matrix viscosity, matrix and composite glass transition temperature (T g ), as well as composite mechanical properties including storage modulus, tensile, bending, interlaminar shear and Charpy impact properties. Although the epoxy resin (EP) and FR decreased the T g , even the flame retarded CE/EP blends had at least 22°C higher T g than the benchmark DGEBA composite. As for the mechanical properties, as a result of higher interlaminar shear strength suggesting better fibre-matrix adhesion, the CE/EP blends managed to over-perform the reference CE in most cases: The 2% phosphorus (P)-containing CE/EP composite had 25% higher tensile strength than the CE reference. The bending strength of the blends remained in the same range as the reference, while the impact resistance significantly increased in comparison to CE, especially in flame retarded composites.
