Abstract: Today, many FRP fabricators are challenged with finding and retaining qualified and experienced operators to meet current production demands. To address these needs, Ashland introduced Derakane™ Signia™ (DS) epoxy vinyl ester resin technology. This resin is based on the historical legacy of Derakane’s (D) performance but with modernized features such as lower styrene emissions, improved usability, fabrication efficiency, and longer shelf-life. DS features create a foundation for further benefits downstream, such as greatly reduced styrene odor in finished parts, cure kinetics that reduce manufacturing steps and surface cure characteristics that lead to reduced grinding. Combined, these features provide better overall shop cleanliness and a more desirable workplace.

Our results show that there is a considerable shift in tan δ peak location (damping peak), which is associated with the glass-rubber transition. At a high loading of polyaniline copolymer (SPNEAC), the glass transition temperature of the nanocomposites decreased with increasing SPNEAC content, however at low weight fraction of the copolymer of about 0.25wt%, a slight increase in the Tg to 406.3 ˚C was obtained.
