Study of flame retardancy of carbon nanofiber paper sheets in glass fiber-reinforced polyester composites
In recent years, more severe requirement of budget and safety from industrial fields, especially space exploration and defense fields, demand a new class of materials whose characteristics can satisfy both various engineering requirement and strict safety standard. The latter demands materials to have good thermal properties and significantly improved fire retardant property. In this research, multifunctional materials with layered structures are made from polyester resin, glass fiber mats and carbon nanofibers (CNF). CNFP are added to the resin component of the composite laminates as additives in pulverised form and carbon nanofiber paper (CNFP) sheets respectively. Their flammability behaviors are investigated with cone calorimeter under well-controlled combustion conditions. Their heat release rate and other test parameters are compared and discussed, such as ignition time, heat release rate (HRR) and peak heat release rate (PHRR). Although its PHRR sharply increased to higher level for CNFP reinforced composite laminates, its HRR curve is lowered greatly in most flaming time. Therefore, the pre-incorporated CNFP may act as an excellent insulator and mass transport barrier, improving the flame retardant property.
