“…While the DC conductivity originates from the translational motions of charge carriers, the conductivity dispersion is related to their correlated short-range transport and, naturally, shifts to higher frequencies with temperature. On the other hand, the step-like feature of conductivity in the middle frequency range is related to the relaxation at the interfaces between regions of different conductivity [ 21 ], i.e., PLA matrix and glass fibers. This result indicates that the PLA matrix in the composites is not continuous but is strongly intersected with the glass fibers which block the charge carrier transport.…”

The aim of this study is to investigate the influence of different glass fibers made of commercial silicate, borosilicate, and laboratory-made iron–phosphate compositions, on the preparation of polylactic acid (PLA) composites and their structural and physical properties. The thermal, structural, and electrical properties of prepared PLA–glass fiber composites were studied using differential scanning calorimetry, X-ray diffraction, microscopy, and impedance spectroscopy. The structural as well as morphological, thermal, and electrical properties of all PLA–glass composites were found to be very similar and independent of the composition and aspect ratio of glass fibers. All types of glass fibers improve mechanical properties, increase thermal stability, and decrease the electrical conductivity of PLA, thereby producing mechanical strong electrically insulating composite material with potential in various applications.
