Composition of the studied epoxy resin-based samples with natural additives.

Sample	Composition	Resin Content [%]	Starch Content [%]	Quercetin Content [%]
R	referential sample (epoxy resin with flame retardants)	100	0	0
R/S15	sample consisted of epoxy resin with flame retardants and 15 phr * of potato starch	87	13	0
R/S15/Q2	sample consisted of epoxy resin with flame retardants and 15 phr * of potato starch and 2 phr * of quercetin	85	13	2

* phr—parts per hundred resin with flame retardants.
