Characterization of Polyimide Matrix Resins and Prepregs [PDF]
Graphite/polyimide composite materials are attractive candidates for a wide range of aerospace applications. They have many of the virtues of graphite/epoxies, i.e., high specific strengths and stiffness, and also outstanding thermal/oxidative stability.

Development and fabrication of bismaleimide-graphite composites [PDF]
The successful fabrication of high temperature resistant composites depends mainly on the processability of the resin binder matrix. For two new bismaleimide type resins the processing of graphite fabric prepregs to composites is described.

Functional Dependences for Internal Friction Forces in Prepregs during Deformation
Механика машин, механизмов и материалов, 2011 For prepregs, which are orthotropic multi-layered structure on the basis of glass smooth weaving fabrics, having an ordered arrangement of yarn layers and impregnated with a resin in the uncured state of polymers at plane stress state, were found the ...
