Abstract

The existing phenolic resins used in aircraft interiors are being phased out owing to occupational health concerns. Our research partner, Zodiac Aerospace, needs new materials capable of meeting mechanical as well as flame, smoke, and toxicity (FST) requirements of aircraft interior applications. Novel benzoxazines have been synthesized to achieve these requirements and tailored to both resin transfer molding (RTM) and prepreg processing applications. RTM is a closed-molding composite manufacturing process capable of producing high tolerance parts, but it requires carefully matched viscosities and pressures to achieve these standards. We have customized an RTM system for this application.Prepreg manufacturing is commonly used for aircraft interior applications, and earlier Zodiac grants helped developed a small-scale treater to produce and test prepreg. As part of this research, both water-based and solvent-free benzoxazine systems were formulated for prepreg manufacturing. Target temperatures and viscosities were identified for each of these applications. A rheometer was used to measure resin viscosities as well as cure kinetics, which was supplemented with studies using differential scanning calorimetry. Resin performance was also assessed by testing FST using a vertical burn chamber.
