LaRC-160 - A new 550 F polyimide laminating resinA new addition polyimide, LaRC-160, based on liquid monomers has been prepared. The essentially solventless prepreg retains good drape and tack. Unidirectional HT-S composites were fabricated and tested before and after aging at temperatures between 505 K and 589 K (450 F and 600 F). Excellent retention of mechanical properties was realized after 2000 hours at 547 K (525 F). This material should be a candidate for solventless prepregging due to the liquid nature of the monomeric mixture.
