Abstract
The thermal properties of epoxy composites filled with boric acid fine powder at different percentage were studied. Epoxy composites were prepared using epoxy resin ED-20, boric acid as flame-retardant filler, hexamethylenediamine as a curing agent. The prepared samples and starting materials were examined using methods of thermal analysis, scanning electron microscopy and infrared spectroscopy. It was found that the incorporation of boric acid fine powder enhances the thermal stability of epoxy composites.
Highlights
Epoxy resins are one of well-known thermosetting polymers and used as construction material, for coating and adhesive applications, which can be reinforced with additives for obtaining high strengths and good chemical resistances

They noted that the addition of bentonite increases the thermal stability of the UP resin. %) the addition of clay had no effect on the thermal stability of the epoxy matrix, whereas for higher concentration Carrasco and Pagès [2] showed that, at low clay contents (up to 5 wt. %) the addition of clay had no effect on the thermal stability of the epoxy matrix, whereas for higher concentration (10 wt. %)
