Carboxyl-Terminated Butadiene-Acrylonitrile-Modifl Epoxy Resin and Its Graphite Fiber-Reinforced Composite... 

The purpose of the present investigation was to study the trimerization of aromatic nitriles under the conventional resin/fiber composite fabrication conditions using p-toluenesulfonic acid as a catalyst. Trimerization parameters investigated included reaction temperature, pressure, time, and concentration of catalyst. The influence of the nature of aromatic nitriles on trimerization was also studied. Also presented are preliminary results on the use of the catalytic trimerization of the nitrile-terminated imide oligomers to fabricate graphite fiber reinforced composites. 

Polvimide/Graphite Fiber Reinforced Composite. Since aromatic nitrile-terminated imide oligomers are similar in nature as p-cyanophthalanil and possess the same functionality as terephtiijilonitrile, they ould be able to trimerize smd form the s-triazine ring containing polymers under the similar reaction conditions. 

Fig. 5.66 Reflected light micrograph of polished carbon fiber composites are shown fibers are white, voids (holes) are black, and the resin is gray in color due to surface reflectivity. A section of a graphite fiber reinforced composite (A) shows a complex arrangement of fibers with uniform wetting and packing. Single ply carbon fiber panels (B) embedded in epoxy and polished are uniformly packed. Higher magnification micrographs show detail is possible by this technique for fibers oriented parallel (C) and perpendicular (D) to the polished surface.
