Bio-based structural composite materials for aerospace applications

Author: John, Maya J ; Anandjiwala, RD ; Wambua, P ; Chapple, Stephen A ; Klems, T ; Doecker, M ; Goulain, M ; Erasmus, Louwrence D Date: Sep 2008 Currently, one of the research programs at CSIR is focused on developing composites from natural fibre and phenolic matrices to be used as side panels in aircraft structures. Efforts are underway to solve the issues related to strength, ... Read more
Enhanced adsorptive degradation of Congo red in aqueous solutions using polyaniline/Fe0 composite nanofibers

Author: Bhaumik, M ; McCrindle, RI ; Maity, Arjun Date: Jan 2015 In this study, a simple approach was described for the fabrication of composite nanofibers (CNFs) of polyaniline/Fe0 (PANI/Fe0) using a template-free method for the reductive degradation and removal of Congo red (CR) from aqueous solutions. ...

Laser metal deposition of titanium aluminide composites: A review

Author: Abdulrahman, KO ; Akinlabi, ET ; Mahamood, RM ; Pityana, Sisa L ; Tlotleng, Monnamme Date: 2018 Development of additive manufacturing (AM) from three dimensional printers with ability of producing parts having no need for tooling continue to wax stronger in the manufacturing field. Laser metal deposition, a technique in AM is usually ... Read more
Mechanical and microstructural evaluation of laser assisted cold sprayed bioceramic coatings: potential use for biomedical applications

Author: Tlotleng, Monnamme ; Akinlabi, E ; Shukla, M ; Pityana, Sisa L Date: Feb 2014 Coatings of commercial pure titanium (CP)-Ti and HAP bio-ceramic were synthesised on Ti-6Al-4V substrate using laser assisted cold spray (LACS) deposition technique. The LACS system comprised of 4.4 kW Nd:YAG laser system, AT-12000HPHV 5000PSI ... Read more
Open source implementation of a user material subroutine for composite materials

Author: Botha, Natasha ; Inglis, H Date: Sep 2018 The modeling and simulation of composite materials requires the incorporation of anisotropic material models, as well as appropriate failure criteria or damage models. This was normally done by developing in-house codes or writing additional ... Read more
Polyaniline-clay composite-containing epoxy coating with enhanced corrosion protection and mechanical properties

Author: Motlatle, Abesach M ; Ray, Suprakas S ; Scriba, Manfred R Date: Nov 2018 The corrosion of steel is a worldwide industrial problem. In this study, we demonstrate that polyaniline (PANI), an extensively studied additive for organic coatings that affords corrosion protection, can be imbedded in epoxy, as a pigment ... Read more
Removal of boron from aqueous solution using magnesite and bentonite clay composite

Author: Masindi, Vhahangwele ; Gitari, MW ; Tutu, H ; De Beer, Morris Date: Mar 2015 The removal of boron from industrial effluents using the composite was studied in batch equilibration technique. The effects of equilibration time, adsorbent dosage, concentration and pH on removal of boron were investigated. The experiments ... Read more
Selective removal of Cr(VI) from aqueous solution by polypyrrole/2,5-diaminobenzene sulfonic acid composite

Author: Kera, Nazia H ; Bhaumik, M ; Ballav, N ; Pillay, K ; Ray, Suprakas S ; Maity, Arjun Date: Aug 2016 A polypyrrole/2,5-diaminobenzenesulfonic acid (PPy/DABSA) composite, synthesised by the in situ oxidative polymerization of pyrrole in the presence of DABSA, was studied as an adsorbent for the removal of Cr(VI) from aqueous solution. The ... Read more
