Development and characterization of new phosphorus based flame retardant tetraglycidyl epoxy nanocomposites for aerospace application

A study was made in the present investigation on the development and characterization of triphenyl phosphine oxide based phosphorus tetraglycidyl epoxy nanocomposites denoted as 'C' and to find out its suitability for use in high performance applications. The synthesized resin was characterized by Fourier transform infrared spectra (FT-IR) and H-1, C-13 nuclear magnetic resonance (NMR) spectra. Nanoclay and POSS-amine nano-reinforcements denoted as N1 and N2 were incorporated into the synthesized epoxy resin. Curing was done with diaminodiphenylmethane (DDM) and (3-aminophenyl) phenylphosphine oxide (BAPPO) curing agents denoted as and , respectively. Mechanical, thermal, flame retardant, water absorption behaviour and electrical properties of the epoxy nanocomposites were studied and the results are discussed.
