“…Alpha-grass stalks had 45% alpha-cellulose, 24.1% gamma-cellulose, 23.4% lignin, 7.6% extractives, and 3.2% ash contents (w/w). This composition agreed with other published studies (Belkhir et al 2013;Ben Brahim and Ben Cheikh 2007;Marrakchi et al 2011;Nadji et al 2006;Paiva et al 2007). However, other researchers found lower lignin contents (Bouiri and Amrani 2010).…”

Alpha-grass was studied as the reinforcement in a starch-based polymer matrix. Mater-bi®-Y was chosen as a matrix due to its Young's modulus, in line with that of polypropylene. The test specimens were injection molded and tensile tested. The obtained results were compared to glass fiber reinforced polypropylene. The reinforcing fibers increased the Young's modulus significantly, obtaining values up to 7.2 GPa, comparable to those obtained with reinforced polypropylene. The contribution of the fibers to the final composite Young's modulus was also studied, and it was found that was in line with other natural fibers contribution to polypropylene-based composites. Finally, it was found that the value of the efficiency factor of the module remained similar to that of natural fiber reinforced polypropylene.

“…28 Studies done by Brahim and Cheikh on alfa reinforced polyester composites with different fibre orientation (0°, 10°, 30°, 45° and 90°) found that the tensile strength and modulus decreased with an increase in angle from 150 MPa down to 18 MPa, and 122.3 GPa down to 5 GPa, respectively. 29 The decrease in modulus for the 10° orientation was found to be less than 7% when compared to the 0° (longitudinal direction), and was tremendously decreased for increasing angles up to the 90° (transverse direction). However, most researchers have focused on random orientation either in the form of short or long fibres, and only a few researchers have examined the yarn structure of fibres used as reinforcement.…”

“…Unidirectional composites with Young's modulus of around 30 GPa and tensile strengths of 550 MPa [242,243] were created (compared to a pure fibre strength of 700 MPa). As such, these composites sometimes out-performed those of traditional natural fibre composites by a factor of two and are among the highest ever reported for a natural fibre-reinforced composite [266][267][268][269][270][271][272][273]. In fact, as the process relies on selective dissolution of the outer fibre skins, the process works extremely well with natural cellulose, where the outer layers of the fibres, which are dissolved, mainly consist of disordered cellulose, while the core, which remains, consists of highly oriented cellulose [274,275].…”

Review: current international research into cellulose nanofibres and nanocomposites

This paper provides an overview of recent progress made in the area of cellulose nanofibre-based nanocomposites. An introduction into the methods used to isolate cellulose nanofibres (nanowhiskers, nanofibrils) is given, with details of their structure. Following this, the article is split into sections dealing with processing and characterisation of cellulose nanocomposites and new developments in the area, with particular emphasis on applications. The types of cellulose nanofibres covered are those extracted from plants by acid hydrolysis (nanowhiskers), mechanical treatment and those that occur naturally (tunicate nanowhiskers) or under culturing conditions (bacterial cellulose nanofibrils). Research highlighted in the article are the use of cellulose nanowhiskers for shape memory nanocomposites, analysis of the interfacial properties of cellulose nanowhisker and nanofibrilbased composites using Raman spectroscopy, switchable interfaces that mimic sea cucumbers, polymerisation from the surface of cellulose nanowhiskers by atom transfer radical polymerisation and ring opening polymerisation,
