Summary

A model composite system was synthesized through in-situ polycondensation of Polyamide 6 around nanoscopic inorganic particles, whose size and concentration were varied. The filler influence on the crystallinity of the composite and its state of dispersion were characterized. The mechanical characterization was carried out below and above the glass transition of the chosen matrix, from the elastic region up to the ultimate properties. This was completed by scattering experiments under synchrotron radiation, while the sample were deformed in-situ.
