摘　　要：为了提高玻璃纤维增强聚合物基复合材料(GFRP)的阻燃性能,采用由微流控技术制备的FR-PN@ETPTA阻燃微胶囊改性环氧树脂基GFRP。采用垂直燃烧试验、锥形量热试验和落锤试验,研究阻燃微胶囊FR-PN@ETPTA对GFRP阻燃性能、燃烧性能和抗冲击性能的影响。试验结果表明:阻燃微胶囊FR-PN@ETPTA能明显提高GFRP的阻燃性能,相比FR-PN阻燃剂,添加阻燃微胶囊FR-PN@ETPTA的GFRP表现出更好的燃烧行为,当添加量为10wt%时,阻燃效果最佳;阻燃微胶囊FR-PN@ETPTA的加入能有效降低阻燃剂对GFRP抗冲击性能的负面影响,添加了10wt%阻燃微胶囊FR-PN@ETPTA的GFRP抗冲击性能最佳。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.
