FEATURE “Natural fibres” g…/… Industrial applications for natural-fibre-reinforced composites polluting emissions: around 50% of the UK’s CO2 emissions comes from civil constructions. More information The Second International Conference on Innovative Natural-Fibre Composites for Industrial Applications will take place in April 2009, declared Year of Natural Fibres by the FAO. The main topic will be applications for green composites. More information: www.diaa.uniroma1.it/docenti/ c.scarponi/conferenza2009/fibrenaturali09.html A step-by-step approach in aeronautical construction As far as aeronautical structures are concerned, the situation is radically different for several reasons: • high load levels, • mechanical and/or thermal and/or acoustic fatigue, • influence of environmental variables and additional durability, reliability and maintainability requirements, • need for reproducible mechanical characteristics and, more generally, “confidence” on a material’s performance, • certification requirements (except for ultralight aircraft). Fig. 3: Hemp/glass fibre rud-der prototype for the Storm 280 SI ultralight airplane. the interface to improve fibre-matrix adhesion. A number of chemical treatments improving adhesion are described in literature. Some of them were successfully tested, producing higher performance than untreated materials. RTM (Resin Transfer Moulding) is considered as a particularly suitable manufacturing technology for aeronautical construction, also because of its considerable cost/benefits advantages as compared with traditional vacuum bagging and autoclave technologies. The next step will involve electromagnetic characterization (for potential future applications in airplane radomes) and mechanical tests involving time-ambient variables, such as wet, hot and hot-wet tests. First, the idea is to introduce NFC in the construction of nonprimary structural parts for ultralight aircraft (the certification procedures are not applicable in this case) and to deal with “certified aviation” later. Thanks to their low weight and good insulating properties, NFC could be used for interiors components like hatboxes, seats, tables or sidewall panels, and for non-structural exterior applications such as radomes, fairings or wing-fuselage junctions. As a consequence, the substitution with a new material has a high impact on the costs and times required by the certification procedures. The process is usually long and costly, due to testing and numerical simulations. For these reasons, the University of Rome’s Dipartimento di Ingegneria Aerospaziale and Dipartimento di Ingegneria Chimica e dei Materiali decided to proceed slowly, step by step, to introduce NFC in aeronautical construction. The researchers focused on four main research lines in order to improve/determine: • quality of processes, • mechanical characteristics and their reproducibility, • impact strength, • Life Cycle Assessment (LCA) & environmental impact. In-depth studies were conducted first on jute (and jute/glass hybrid laminates) and later on hemp, processed with thermosetting and thermoplastic matrices. The aim was to achieve good chemical/physical and mechanical characterization, focusing on the differences and the reproducibility of mechanical properties among various production batches/stocks. A wide array of tests were performed, ranging from traction, compression and bending to impact. SEM analysis was used to investigate the microstructure and interfacial properties. The internal damage status of specimens tested at different loads was detected by acoustic emission and ultrasound technologies based on reflection. Additional research is required to study the basic materials, the chemical-physical compatibility between fibres and matrix, and Fig. 4: Bamboo fibre boat hull, hemp table, flax chair and jute-reinforced honeycomb core. To demonstrate the recent applications of such materials, several examples were presented at the above-mentioned conference in Rome, including a hemp/glass rudder prototype for an ultralight airplane (Figure 3), a composite boat hull, chairs, lamps, tables, seats, casings, boards, road signs, train interior parts, NFreinforced honeycomb cores, and more (see Figure 4).
