Agave nonwovens in polypropylene composites: mechanical and thermal studies

Author: John, Maya J ; Sikampula, N ; Boguslavsky, L Date: Mar 2015 Blends of agave fibres with wool waste, pineapple leaf fibres and polypropylene fibres were manufactured by needle-punching technique. Composites were prepared with polypropylene matrix by the process of compression moulding. The effects of ... Read more
Characteristic effects of alloying elements on ß solidifying titanium aluminides: A review

Author: Raji, Sadiq Abiola ; Popoola, API ; Pityana, Sisa L ; Popoola, OM Date: Jul 2020 The high strength-to-weight ratio property of titanium aluminide (TiAl) based intermetallic alloys makes researchers regard this type of material as a potential replacement for the heavier superalloys of nickel. These alloys have been applied ... Read more
Effect of accelerated thermal ageing on the selective solar thermal harvesting properties of multiwall carbon nanotube/nickel oxide nanocomposite coatings

Author: Roro, Kittessa T ; Mwakikunga, Bonex W ; Tile, N ; Yalisi, B ; Forbes, A Date: May 2012 Varying amounts of dispersed multiwalled carbon nanotubes in NiO have been used to develop composites that absorb the solar energy very well but lose very little through emission. Determination of absorptance, asol, and emissivity, ether, ... Read more
GaN nanostructures-poly(vinyl alcohol) composite based hydrostatic pressure sensor device

Author: Linganiso, EC ; Rodrigues, R ; Mhlanga, SD ; Mwakikunga, Bonex W ; Coville, NJ ; Hümmelgen, IA Date: Dec 2013 The wide band-gap semiconductor material gallium nitride was synthesized using a one step microwave-assisted solution phase technique. The synthesized GaN nanocrystals showed an intense ultraviolet-blue emission typical of GaN materials. ... Read more
Image processing towards the automated identification of nanoparticles in SEM images

Author: Botha, Gerda N ; Wessels, Gert JC ; Botha, Natasha ; Van Eden, Beatrice Date: Jan 2019 SEM images are crucial in the characterisation of material properties. These images can be very hard to interpret without any prior knowledge of the material. This paper discusses a pre-processing method for assisting convolutional Neural ... Read more
Multiwall carbon nanotube/nickel oxide nanocompositecoatings: Sol-gel deposition and characterization

Author: Roro, Kittessa T Date: Sep 2011 Due to their unique electronic and optical properties nanocomposite materials have wide range of applications in solar energy conversion. In this study, multiwalled carbon nanotubes (MWCNTs)/Nickel oxide (NiO) nanocomposites were successfully ... Read more
A review on melt-state viscoelastic properties of polymer nanocomposites

Author: Hyoung, JC ; Ray, SS Date: Oct 2011 The mixing of polymer matrices with nanoparticles to form composite materials has been an area of great research interest. The mechanical and rheological properties of such composite materials are directly related to the properties of the ... Read more
Sisal fibre pull-out behaviour as a guide to matrix selection for the production of sisal fibre reinforced cement matrix composites

Author: Mapiravana, Joseph ; Dlamini, Mandla Date: Dec 2011 Natural fibre reinforced cement composites are promising potential materials for use in panelised construction. The structural properties of these composite materials are yet to be fully understood. As the role of the natural fibre is to ... Read more
Solar absorption and thermal emission properties of multiwall carbon nanotube/nickel oxide nanocomposite thin films synthesized by sol-gel process

Author: Roro, Kittessa T ; Tile, N ; Mwakikunga, Bonex W ; Yalisi, B ; Forbes, A Date: May 2012 Multiwall carbon nanotubes (MWCNTs)/nickel oxide (NiO) nanocomposites were successfully prepared by a sol–gel process and coated on an aluminium substrate. The MWCNTs were chemically functionalized and then added into NiO alcogels, and magnetic ... Read more
Strategic opportunities and challenges for composites R&D in South Africa - a CSIR perspective.

Author: Du Preez, WB ; Corderley, G Date: Dec 2007 The utilisation and prominence of composite materials have been increasing significantly over the past decade in technologically demanding industry sectors, such as aerospace and automotive. It has been accompanied by growing needs for research ... Read more
Synthesis, characterization and optimization of poly(p-phenylenediamine)-based organoclay composite for Cr(VI) remediation

Author: Mdlalose, L ; Balogun, Mohammed O ; Setshedi, K ; Tukulula, M ; Chimuka, L ; Chetty, A Date: Apr 2017 The contamination of the water supply with high levels of heavy metals from various human and industrial activities continues to present a major environmental problem. Heavy metals such as hexavalent chromium (Cr(VI)) are of particular concern ... Read more
