Flame retardancy analysis of epoxy resins containing nonphosphorus flame retardants in terms of the FRI values as a function of NP type and content. Symbols are indicative of different types of NP type of FR used. Hollow symbols are indicative of fiber-incorporated composites with details earlier given in the bottom of Table 1 as notes a to h.
