woven hybrid biocomposite mechanical properties of woven kenaf Bast Fibre oil palm empty fruit bunches hybrid reinforced poly hydroxybutyrate biocomposite as non structural building materials
Construction and Building Materials, 2017Co-Authors: Seyed Meysam Khoshnava, Raheleh Rostami, Mohammad Ismail, Abdul Razak Rahmat, Babatunde Ezekiel OgunbodeAbstract:Green or Biocomposite materials encompass biopolymers and natural fibers (NFs) from renewable resources, which is helped to eliminate non-renewable waste, reduce raw material usage, and lessen greenhouse gas emissions. This paper aimed to assess and develop specific biocomposite in terms of mechanical properties, which prepared by lamination and compression molding method. The woven kenaf Bast Fibre (KBFw) is deliberated as reinforcement in this study due to the high tensile strength which was hybridized with oil palm empty fruit bunches (EFB) due to high toughness of EFB for covering the impact properties of biocomposite. The polyhydroxybutyrate (PHB) is a common biodegradable polymer that is targeted as matrix for green composite. The triethyl citrate (TEC) was chosen as plasticizer for improving flexibility and handling of PHB films. The scanning electron microscope was used to understand and investigate the tensile-fractured surface of different hybrid biocomposite. The results show that the tensile and flexural properties would be increase when NFs with higher tensile strength was used as skin Fibre in term of hybrid composite. Conclusively, the flexural stiffness of biocomposite increase when the KBFw PHB biocomposite is hybrid with FEB reinforcement. The tensile and flexural test of KBFw/EFB hybrid reinforced PHB biocomposite with 11 layers (sample E) is determined that sample E has capability to replace with some wood and woody production.

The first plant Bast Fibre technology: identifying splicing in archaeological textiles
Archaeological and Anthropological Sciences, 2019Co-Authors: Margarita Gleba, Susanna HarrisAbstract:Recent research into plant Bast Fibre technology points to a Neolithic European tradition of working Fibres into threads by splicing, rather than draft spinning. The major issue now is the ability of textile specialists and archaeobotanists to distinguish the technology of splicing from draft-spun Fibres. This paper defines the major types of splicing and proposes an explicit method to observe, identify and interpret spliced thread technology. The identification of spliced yarns is evaluated through the examination of textiles from Europe, Egypt and the Near East. Through the application of this method, we propose that the switch from splicing to draft spinning plant Fibres occurred much later than previously thought. The ramifications of this shift in plant processing have profound implications for understanding the chaîne opératoire of this ubiquitous and time-consuming technology, which will have to be factored into social and economic reconstructions of the past.

Effects of plant growth regulator treatments on stem vascular tissue development in linseed (Linum usitatissimum L.)
Industrial Crops and Products, 2011Co-Authors: Ryan R. Mckenzie, Michael K. DeyholosAbstract:Abstract Linseed (Linum usitatissimum L.) is a widely grown source of industrial and edible oil. Other varieties of the same species (flax) are cultivated for the long, strong Bast Fibres of their stems. The Bast Fibres of linseed generally go unused, although there is growing interest in developing linseed into a dual-purpose flax from which both seed and Fibre could be utilized. Towards this objective, an improved understanding is required of the role of plant growth regulators in stem and Fibre development in linseed. We have tested the effects of applying varying combinations of gibberellic acid (GA3), the auxin indole-3-acetic acid, and a GA biosynthesis inhibitor (paclobutrazol) to an elite linseed variety (CDC Bethune). Results showed that GA stimulated stem elongation, stem expansion and the proliferation, expansion, elongation and cell wall thickening of xylem Fibres. The impact of GA on phloem tissues was less apparent, although GA had a positive effect on the number of Bast Fibres observed in stem transverse section, and GA3 application in combination with IAA increased the thickness of Bast Fibre secondary walls nearly two-fold. Other than the Bast Fibre cell walls, IAA treatments (alone or in combination with GA3) did not affect most aspects of linseed stem development, suggesting that the observed effects of GA were not mediated by cross-talk with IAA. The relationships defined here between GA, stem architecture, and Bast Fibre properties in linseed provide a useful framework for manipulation of Fibre properties through breeding, biotechnology, and field treatments.

Microarray analysis of Bast Fibre producing tissues of Cannabis sativa identifies transcripts associated with conserved and specialised processes of secondary wall development
Functional plant biology : FPB, 2007Co-Authors: Mary A. De Pauw, John Vidmar, Joann Collins, Rick A. Bennett, Michael K. DeyholosAbstract:The mechanisms underlying Bast Fibre differentiation in hemp (Cannabis sativa L.) are largely unknown. We hybridised a cDNA microarray with RNA from Fibre enriched tissues extracted at three different positions along the stem axis. Accordingly, we identified transcripts that were enriched in tissues in which phloem Fibres were elongating or undergoing secondary wall thickening. These results were consistent with a dynamic pattern of cell wall deposition involving tissue specific expression of a large set of distinct glycosyltransferases and glycosylhydrolases apparently acting on polymers containing galactans, mannans, xylans, and glucans, as well as raffinose-series disaccharides. Putative arabinogalactan proteins and lipid transfer proteins were among the most highly enriched transcripts in various stem segments, with different complements of each expressed at each stage of development. We also detected stage-specific expression of brassinosteroid-related transcripts, various transporters, polyamine and phenylpropanoid related genes, and seven putative transcription factors. Finally, we observed enrichment of many transcripts with unknown biochemical function, some of which had been previously implicated in Fibre development in poplar or cotton. Together these data complement and extend existing biochemical models of Bast Fibre development and secondary wall deposition and highlight uncharacterised, but conserved, components of these processes.
