Abstract

In this study, two types of carbon fiber reinforced polymer (CFRP) flame retardant composites, CFRP@Mat EG-GF and CFRP@Mat EG-GF-MW (EG, GF, and MW are the acronyms of expandable graphite, glass fiber and mineral wool, respectively), were prepared via compression molding, with expandable graphite-based mat incorporated at the surface of the CFRP. The results showed that compared with the control CFRP, both CFRP@Mat EG-GF and CFRP@Mat EG-GF-MW passed vertical burner test and 45° burner test according to FAR25.853. Moreover, the limiting oxygen index (LOI) values of both CFRP@Mat EG-GF and CFRP@Mat EG-GF-MW were increased, and the peak of heat release rate (PHRR) and total heat release (THR) were reduced. Besides, CFRP@Mat EG-GF-MW had higher flame retardancy than CFRP@Mat EG-GF . This was attributed to the formation of a more stable and dense carbon layer structure. The mechanical test results showed that the tensile strength of CFRP@Mat EG-GF-MW was higher than that of CFRP@Mat EG-GF .
