Conclusions
-
1.
The weight loss of the materials investigated in the 300–1100°C interval ranges from 10−4 to 10−6 g/(g·sec).
-
2.
The WSS-base material begins to experience vigorous breakdown (by smouldering) on heating to 550°C, while all of the remaining carbon materials tested neigher ignite, more smoulder when air is admitted to the furnace in the 300–1100°C temperature interval (holding time of 15 min).
