Abstract
Five resin systems, Epon 813, Derakane 510A, Hetron 197AT, Hetron 27196 and Hetron 692TP-25 were mixed one at a time with four different fire retardants and made up into composite panels. The four fire retardants were: 10% zinc borate, 25% alumina trihydrate, 5% Nyacol and 5% antimony trioxide. Tensile and impact tests were carried out at room temperature and -40C on specimens cut from each of the 20 panels. Half of the specimens were immersed in sea water for 60-65 days prior to tensile or impact testing. The fire retardants affected the mechanical properties of each resin system differently, but no significant trend emerged.
