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
Effect of enzyme and oxidative treatments on the properties of coarse wool and mohair

Author: Barkhuysen, FA ; Chapple, Stephen A ; Blunt, J ; Lemon, H Date: Sep 2005 The main disadvantage of coarse wool and mohair is their harshness, making them unacceptable to the consumer. The best way to improve the softness of coarse fibres is by a chemical treatment. In this regard, a variety of options are available ... Read more
Effect of expandable graphite on thermal and flammability properties of poly(lactic acid)-starch/poly(E-caprolactone) blend systems

Author: Mngomezulu, ME ; Luyt, AS ; Chapple, Stephen A ; Mathew, Maya J Date: Sep 2018 The effect of expandable graphite (EG) on the flammability and thermal stability of a poly(lactic acid) (PLA)-starch/poly(E-caprolactone) (PCL) blend was investigated. The samples were prepared by melt-mixing and characterized by thermogravimetric ... Read more
Exploration of nano-finished non-wovens for potential use in protective clothing for agricultural workers in South Africa

Author: Zwane, PE ; Chapple, Stephen A ; Masarirambi, MT Date: 2011 The global trade requirements have made protective clothing paramount in the agricultural sector. The aim of the study was to find the views of farmers on the use of protective garment for the agricultural sector in South Africa, and to measure ... Read more
Flame retardant treated flax fibre reinforced phenolic composites: Ageing and thermal characteristics

Author: Molaba, TP ; Chapple, Stephen A ; John, Maya J Date: Jan 2018 In this study, flax composites were prepared from flax fabric and phenolic resin. Chemical treatments were imparted to the fabric to improve adhesion between the fabric and the phenolic matrix. Diammonium phosphate was applied to improve the ... Read more
Influence of precursor ratios on the properties of cotton coated with a sol-gel flame retardant

Author: Chapple, Stephen A ; Ferg, E Date: Nov 2006 Cotton has many desirable properties, but is flammable. The flame retardant treatment of cotton is an important textile process. To study the effect of a sol-gel phosphate-based flame-retardant coating on fabric properties (flammability, ... Read more
Mechanical, thermal, and fire properties of biodegradable polylactide/boehmite alumina composites

Author: Das, K ; Ray, Suprakas S ; Chapple, Stephen A ; Wesley-Smith, J Date: May 2013 Boehmite alumina (BAl) was investigated in terms of its use as an filler to improve the inherent properties of polylactide (PLA). Composites of PLA with different loadings of BAl were prepared by melt-blending. Morphological analysis using ... Read more
Poly(lactic acid)-starch/expandable graphite (PLA-starch/EG) flame retardant composites

Author: Mngomezulu, ME ; Luyt, AS ; Chapple, Stephen A ; John, Maya J Date: Jan 2018 This work reports on the effect of commercial expandable graphite (EG) on the flammability and thermal decomposition properties of PLA-starch blend. The PLA-starch/EG composites were prepared by melt-mixing and their thermal stability, volatile ... Read more
