  • Description: Decomposition products generated by fiberglass composites used in construction were identified using Fourier transform infrared (FT-IR) spectroscopy. This bench-scale study concentrated on identification and quantification of highly toxic species. Identifying compounds evolved during thermal decomposition provides an excellent warning system for early fire detection as well as an evaluation of product fire safety performance. Material fire behavior depends on many factors. Ventilation, radiant heat flux, and chemical composition are three factors that can be modeled. Physical observations of composites during thermal decomposition with simultaneous identification and quantification of evolved gases offer researchers in both material development and fire safety an advancement in the state-of-the-art for material testing. Gas analysis by FT-IR spectroscopy identified toxic effluent species over a wide range of exposure temperatures (100 to 1000 °C). Decomposition products were identified by monitoring gaseous species evolving during pyrolysis and combustion. Fiberglass composites with melamine, epoxy, and silicone resins were profiled. Formaldehyde, methanol, carbon monoxide, nitric oxide, methane, and benzene were identified prior to physical evidence of decomposition. Spectral quantification identified toxic concentrations of formaldehyde, carbon monoxide, nitric oxide, ammonia, and hydrogen cyanide as thermal decomposition progressed.
