Characterization of thermoplastic polyamide composite matrix material
The research described here involves a study for a representative matrix resin, the J1-polymer (a polyamide) proposed by DuPont. The research was conducted in parallel with related studies, primarily by other personnel, of graphite fiber/J1-polymer unidirectional composites. X-ray and transmission electron microscopy studies were conducted to examine the structure/morphology of the neat resin. Thermal analysis by differential scanning calorimetry was used to investigate the effects of different heating and cooling rates and various processing conditions. Dynamic mechanical properties of the neat resin were characterized. The fundamental mechanisms of deformation and failure, including creep, crack growth and fracture behaviors, were examined both at room temperature and at elevated temperature. A number of the techniques were extended to characterize the composite as well as the neat resin.
