“…A significant number of ecological conditions must now be considered, and a resource of this type is more environmentally friendly than any other common filler when being obtained, processed, used and neutralised. [3] According to the calculation by Carusa et al [4], the present cost of obtaining plant fibres is one-third of that of glass fibres, one-fourth of aramide fibres and as much as one-fifth of carbon fibres.…”

The purpose of this work was to obtain environmentally friendly natural fibre composites (NFC) from high-density polyethylene (PE-HD) foil and either finely ground sunflower husk or pistachio shells, which both possess physico-mechanical characteristics similar to wood-polymer composite. The composites were prepared from waste materials without the use of additives. It was found that 66% of the sunflower husk grains were from 180 to 850 μm in size, and 88% of the pistachio shell particles were less than 63 μm in size. With the use of a rolling mixer, six mixtures were produced with filler shares amounting to 5, 15 and 30 wt.% of sunflower husk and 15, 35 and 55% of pistachio shell, from which dumbbell-shaped samples were formed via injection processing. The produced materials were analysed for their mechanical properties (impact strength, hardness, tensile strength, Young's modulus and DMA). The morphologies and chemical composition of the filler as well as the morphological properties of the composites (SEM) were also investigated. The chemical constitution and shape of the filler particles affected the investigated properties of the obtained NFC, and the results were especially significant for the properties of impact strength, stiffness and tensile strength.

Due to the dominating advantages of natural fibres such as biodegradability, eco-friendliness, nominal cost, low density and high specific strength, they are being used opposite to synthetic fibres in many industrial applications. Despite many advantages, these fibres face some limitations such as higher moisture uptake, quality variations, low thermal stability, and poor compatibility with polymeric matrix. To overcome these limitations, chemical treatments of these fibres were found to be the most suitable method to improve adhesion with polymers, increase their strength and water absorption resistance, and improve their composite properties also. Among chemical treatments, alkali treatment is the most widely used and versatile surface modification method of the natural fibres. A good number of research works have been carried out on effect of alkali treatment on the properties of natural fibres and its composites, which motivated for this review. In this paper, the effect of alkali treatment on the properties of natural fibres has been reviewed. In addition, the physical and mechanical properties, thermal analysis and tribological behaviour of its biocomposites are also reviewed. It was concluded that alkali treatment of natural fibres could provide enhanced properties of various bio-composites up to a great extent.

“…Employing natural fibres in fibre reinforced composites has many notable advantages over synthetic fibres, such as lower weight, lower cost and lower carbon footprint [4]. Natural fibre-reinforced composites have therefore received much attention in recent years from composite manufactures and end users in various sectors, including construction [5] and automobile [6], with demand growing at 20-25% year on year [7].…”

Semi-consolidated thermoplastic tapes were produced by spreading flax and polypropylene matrix fibres using a newly developed technology. This lightweight tape was structurally stable and contained 38% flax fibres by volume. The tapes were processed in unidirectional and woven fabric format for composite fabrication. We found that the flax/PP tape-based composites had 60-110% higher flexural modulus and 35-65% higher tensile modulus compared to flax/PP yarn based thermoplastics. Thermoanalytical results showed that the heating conditions used in the tape-making process did not degrade the flax fibres and PP matrix. We conclude that such semi-consolidated flax/PP tapes enable the achievement of properties not seen before for yarn-based composites, and therefore are an important step forward in optimising the reinforcing effect of natural fibres in composite applications.
