Abstract

Abstract: In order to improve the flame retardancy properties of glass fiber reinforced polymer composites (GFRP), FR-PN@ETPTA flame retardant microcapsules prepared by microfluidic technology were used to modify epoxy resin based GFRP. The effects of FR-PN@ETPTA flame retardant microcapsules on the flame retardant properties, combustion performance and impact properties of GFRP were investigated by vertical combustion test, cone calorimetry test, and drop hammer test. The test results indicate that FR-PN@ETPTA flame retardant microcapsules can significantly improve the flame retardancy properties of GFRP. Compared with FR-PN flame retardant, GFRP composites with FR-PN@ETPTA flame retardant microcapsules show better combustion behavior, and the flame retardant effect is the best when the addition amount of FR-PN@ETPTA flame retardant microcapsules is 10wt%. On the other hand, the addition of FR-PN@ETPTA flame retardant microcapsules can effectively reduce the negative effect of flame retardants on the impact resistance of GFRP. In addition, GFRP composites with 10wt% FR-PN@ETPTA flame retardant microcapsules have the best impact resistance.

Key words: microfluidic technology, flame-retardant microcapsule, glass fiber reinforced polymer composites, flame retardant properties, impact resistance
