Figure 1

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