“…This trend is also maintained when analysing fully bio-based composites with varying natural fibre reinforcement in a biosynthesized polymer matrix [51]. However, results of Dissanayake suggested that flax fibres may require similar or higher energy due to the intense use of agrochemicals [46].…”

“…Fourteen LCAs dealing with natural reinforcing fibres have been selected and reviewed [36,[42][43][44][45][46][47][48][49][50][51][52][53]. Most of them compared natural fibres composites with synthetic fibres composites (such as GFRP) for the same applications to demonstrate the competence of the natural counterparts.…”

“…Then usable fibres were extracted from dried stems during scutching, the mechanical separation of fibres from the woody core and bark. Scutching was followed by hackling, a process to remove impurities and residual sugars by combing them out [46]. Some gaps were usually reported within inventory of this raw material processing stage, which could be relevant for impact assessment results.…”

The forecast of growing air transport in the upcoming decades faces the challenge of an increasing environmental impact. Aviation industry is working on promising technologies to mitigate this environmental impact. Lightweight design is a strong lever to lower the fuel consumption and, consequently, with it the emissions of aviation. High performance composites are a key technology to help achieve these aims thanks to their favourable combination of mechanical properties and low weight in primary structures. However, mainly synthetic materials such as petrol based carbon fibres and epoxy resins are used nowadays to produce composite in aviation. Renewable materials like bio-based fibres and resin systems offer potential environmental advantages. However, they have not found their way into aviation, yet. The reasons are reduced mechanical properties and, especially for the use of natural fibres, their flammability. Improvements of these shortcomings are under investigation. Therefore the application of bio-based and recycled materials in certain areas of the aircraft could be possible in the future. Good examples for applications are furnishings and secondary structures. The motivation for this paper is to give an overview of potential environmental properties by using such eco-materials in aviation. Life cycle assessment (LCA) is a tool to calculate environmental impacts during all life stages of a product. The main focus is laid on the bio-fibres flax and ramie, recycled carbon fibres and bio-based thermoset resin systems. Furthermore an overview of environmental aspects of existing composite materials used in aviation is given. Generally, a lack of LCA results for the substitution of synthetic materials by bio-based/recycled composite materials in aviation applications has been identified. Therefore, available information from other transport areas, such as automotive, has been summarized. More detailed LCA data for eco-composite materials and technologies to improve their properties is important to understand potential environmental effects in aviation. aviation, composite, natural fibre, recycled carbon fibre, bio-resin, cabin interior, secondary structure, life cycle assessment (LCA) Citation:Bachmann J, Hidalgo C, Bricout S.

“…Previous LCA studies of natural fibre composites (NFC) are limited. Comparative studies have been based on mass-to-mass comparisons ignoring differences in stiffness between the compared materials [3]. Alternatively, they have resorted to use of simplified micromechanical models for calculating the mechanical properties of the composites [4], not suitable to represent the behaviour of natural fibre composites due to their special characteristics compared to synthetic fibre composites, as pointed out in [5].…”

Natural fibre composites (NFC) are gaining interest in manufacturing because they address some of the environmental problems of traditional composites: use of non-renewable resources, and large impacts related to their production and disposal. Since natural fibres are not yet optimized for composite production, it is crucial to identify the most appropriate applications, and determine the optimal fibre/matrix ratio. A methodology is proposed for early-stage decisions support on selection of bio-composite materials. Results help identify the application with the largest reduction in environmental burden and show that the fibre/matrix combination with the lowest environmental burden also has the best mechanical properties Lifecycle; Composite; Eco-design Methodology
