Development of an impact- and solvent-resistant thermoplastic composite matrix, phase 3 [PDF]

open access: yes
The polyimide from BTDA 1,6-hexanediamine and m-phenylenediamine was selected from a prior study for the present study. Methods to prepare prepreg which would provide low void composites at low molding pressures from the thermoplastic polyimide were ...

Study of catalyst cured LaRC-160/Celion 6000 composites [PDF]

open access: yes
LaRC 160 polyimide was modified with a high temperature peroxide catalyst, USP-138, in an attempt to reduce the final cure temperature to below 316 C. This effort was directed at obtaining a material for 177 C use that would cure at similar temperatures ...
