Experimental Study on Mechanical Behavior of Polypropylene-based Blends with Talc Fillers

by Pham Thi Hong Nga and Van-Thuc Nguyen

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 6, Page # 571–576, 2020; DOI: 10.25046/aj050669

Abstract:

In this report, polymeric composites made from Polypropylene (PP) and talc powder were studied. The talc powder with different portions of 10%, 20%, 30% by weight was used to create samples. The samples were examined by the tensile test and the flexural test according to ASTM D638 and ASTM D790. The surface morphology of the…

by Altamashuddinkhan Nadimalla, Siti Aliyyah Masjuki, Siti Asmahani Saad, Ean Lee Woen, Siti Maisarah Ali and Naseer Ulla

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 1, Page # 302–306, 2020; DOI: 10.25046/aj050138

Abstract:

In fast charging station for Battery Electric Vehicles (BEVs) the three-phase PWM (Pulse Width Modulation) inverters generate parasitic Differential-Mode Voltages (DMV) and Common-Mode Voltages (CMV). Parasitic voltages are a side effect of using the width modulation to shape the phase-to-phase inverter’s voltage. In this article the authors present a mathematical description of the differential-mode (DM)…
