- ¹Samples were 12-ply laminate using #1581 or 7781 glass (otherwise they were neat resin samples).
- ²Sample can also be cured for 1 hour at 77°F + 2 hours at 212°F
- ³The combustible resin content of each laminate shall be verified to 28 to 33.6 percent by weight (the resin content can be verified using the burn out method typically employed for fiberglass reinforced materials). For flammability testing, two ply fiberglass fabric laminate shall be used with the warp direction the same for each ply.
