Flammability Testing of Flame-retarded Epoxy Composites and Phenolic Composites

摘要

Flame-retarded epoxy composites and phenolic composites containing fiberglass, aramid (Kevlar ~R 49), and graphite fiber-reinforcements were tested using the NASA upward flame propagation test, the controlled-atmosphere cone calorimeter test, and the liquid oxygen (LOX) mechanical impact test. The upward flame propagation test showed that phenolic/graphite had the highest flame resistance and epoxy/graphite had the lowest flame resistance. The controlled-atmosphere cone calorimeter was used to investigate the effect of oxygen concentration and fiber reinforcement on the burning behaviour of composites.
