Current–voltage Characteristic Behaviour of dense Zn2SnO4-ZnO ceramics
Journal of The European Ceramic Society, 2007Co-Authors: Y. Iglesias, M. Peiteado, J. De Frutos, A.c. CaballeroAbstract:Abstract The present work deals with the electrical characterization of undoped Zn2SnO4 (ZTO) and SnO2-doped ZnO bulk ceramics in order to clarify the role played by the ZTO spinel type phase in the electrical response of these materials. For this purpose, SnO2-doped ZnO materials with SnO2 concentrations of 0.1, 1 and 10 mol% have been prepared by co-precipitation and undoped ZTO powders have been prepared by a classical mixing oxide procedure. ZTO materials with 90–92% of the theoretical density have been obtained and non-linear Behaviour is observed for ZTO- and SnO2-doped ZnO materials. For SnO2-doped ZnO the appearance of non-linear I–V Behaviour is mainly dominated by the formation of the ZTO phase and the interfaces associated to its presence. ZTO shows a NTC Behaviour that is in disagreement with the PTC Behaviour previously reported in the literature.

investigation of the Behaviour of a chopped strand mat woven roving foam klegecell composite lamination structure during charpy testing
Materials & Design, 2014Co-Authors: Ahmad Mubarak Tajul Arifin, Siti Norul Huda Sheikh Abdullah, Md Rafiquzzaman, Rozli Zulkifli, Dzuraidah Abd Wahab, Amir ArifinAbstract:Abstract This paper presents the investigation of the Characteristic Behaviour of polymer matrix composites under Charpy impact conditions with different design configurations of the laminate structure. The aim of this study was to evaluate the capability of different lamination designs for composite materials, in term of contact load, energy absorption, deflection and damage Behaviour. In this study, laminated panels were fabricated using chopped strand mat (CSM), woven roving fabric (WR) and foam-PVC Klegecell as reinforcement with a combination of epoxy or polyester resin, respectively. Structural panels of composite laminates were produced using a hand lay-up technique. Each configuration design was impact tested to failure. Finite element analyses (FEA) were employed in this study to correlate the experimental value of energy absorption with simulation results. The Characteristics of different reinforcement types, matrix type, hybrid type, architecture and orientation type were studied. These Characteristics need to be considered, due to their affecting the Characteristic Behaviour of the composite lamination structures. Based on the results, it was found that differences in configuration design of the lamination structure of the polymer matrix composites do influence the strength and weakness of the materials.
