Development and study of the thermal and electrical behaviour of TGDDS epoxy nanocomposites for high-performance applications

Abstract

The present work focuses on a comparative study of the thermal and electrical behaviour of N,N 0 -tetraglycidyl diaminodiphenylsulphone (TGDDS) denoted as 'B' to find the suitability for its use in high-performance applications. The synthesis of the tetraglycidyl epoxy was done and they were characterized by FT-IR (Fourier transform infrared spectra) and nuclear magnetic resonance spectra ( 1 H-NMR and 13 C-NMR). Nanoclay and POSSamine nanoreinforcements denoted as N1 and N2 were incorporated into the synthesized epoxy resins. Curing was done using diaminodiphenylmethane (DDM) and bis(3-aminophenyl)phenylphosphine oxide (BAPPO) curing agents denoted as X and Y, respectively. The thermal behaviour of the tetraglycidyl resins and their corresponding nanocomposites was studied by thermogravimetric analysis (TGA). The electrical behaviour, namely dielectric strength, comparative tracking index (CTI), volume resistivity, surface resistivity and arc resistance of the nanocomposites were also studied and the interesting results obtained are discussed.

Enhanced microwave shielding and mechanical properties of multiwall carbon nanotubes anchored carbon fiber felt reinforced epoxy multiscale composites

“…Epoxy resins are well established as thermosetting matrices for advanced structural composites, displaying a series of promising characteristics for a wide range of applications owing to their excellent mechanical properties, low cost, ease of processing, good adhesion to many substrates, and good chemical resistance Meenakshi and Sudhan 2011;Ruban et al 2013). Several fibrous reinforcements, e.g.…”
