This paper describes the results of a joint study undertaken by the U.S. Army Materials Technology Laboratory (AMTL) and the Factory Mutual Research Corporation CFMRC) on fiber reinforced composite materials (FRC) for use in a composite combat vehicle. 

The generation of material vapors can be quantified in terms of 1) relationship between weight loss and sample temperature. AMTL used thermogravimetric techniques for such quantification (J ), and 2) the relationship between the generation rate of material vapors and the heat flux. Factory Mutual Research Corporation (FMRC) has developed a technique using FMRC s Small-Scale Flammability Apparatus (2-10), which was used for the quantification.

Factory Mutual Research Corporation (FM) is also an insurance rating company (for profit). FM rates and approves heater systems, other components, and assembled machinery for use in industrial applications insured by the Factory Mutual Insurance Company. Unlike UL, FM approves products for use in facilities insured by their parent company (and other insurance companies). 

For this reason, attention is now being accorded to the notions of combustion time, heat released, and the opacity, corrosivity and toxicity of smoke. There are many ways to assess these risks but one of the most comprehensive methods is the one developed in the U.S. by A. Tewarson of Factory Mutual Research Corporation, which was the object of a proposal in lEC publication lOB, France 38, May 1984. In its present form, the method does not take account of the corrosivity or toxicity of smoke, but its scope could always be broadened to correct this.

Factory Mutual Research Corporation (AIChE/CCPS, 1994) 5%, 10%, and 15% of the heat of combustion of the quantity of fuel present in the cloud, dependent on the reactivity of the material. Higher reactivity gives a higher efficiency. Use the following efficiencies for the highly reactive materials specified diethyl ether, 10% propane, 5% acetylene, 15%.
