Three important linear aromatic Pis, namely LARC-TPI, LARC-160, and LARC-13 were developed by researchers at NASA-Langley Research Center (37—39) (Fig. 2). 

Semicrystalline Polyimides. Semicrystalline polyimides containing carbonyl and ether groups have been synthesized by the group at the NASA Langley Research Center (37). One such material, designated LARC-CPI, which is an acronym for Langley Research Center—Crystalline Polyimide,...

Another system, developed by NASA Langley Research Center, reportedly shows improved thermal oxidative stability as compared with PMR-15 (117). The resin is named RP-46 and its chemistry is based on BTDE, NE and 3,4 -diaminodiphenylether (3,4 -ODA), and is formulated to a molecular weight of 1500g/mol as in PMR-15. The only difference to PMR-15 is that 3,4 -ODA replaced the MDA and therefore the improved thermal oxidative stability is attributed to this structural change.

In the mid-seventies, G. D. Brewer and R. E. Morris of the Lockheed California Company performed a study for NASA Langley Research Center to define the characteristics of a hydrogen fueled commercial airliner. This comparison was performed for airplanes with short, medium, and long ranges, carrying 130,200, and 400 passengers respectively. Table 7.3 shows the results of this study.
