| Abstract: | The relationship between the microstructure developed during injection molding of a PES/TLCP blend and its properties was investigated . The resulting injection molded structure had a distinct skin-core morphology, where TLCP fibres composed the skin layer and sherical and ellipsoidal particles or "stalamite"ones comprised the core section . The blend exhibits excellent mechanical properties due to in situ formed fibers of the disperse TLCP phase in PES matrix. The blend tensile strength reduces with increasing the melt temperature and the shear rate. |
