“…Damping alleviates the relative motions in an object and converts kinetic energy into heat or other disposable energy types. It has been experimentally proven by Duc et al [2014] that the loss factor which was measured by temperature sweep tests of flax fiber composites was significantly higher than that of glass and carbon fiber composites. In the study by Duc et al [2014], the matrix resin, fiber volume fraction and fiber architecture were kept the same in order to compare the vibration damping properties of natural fibers with that of synthetic fibers.…”

Natural fibers are extracted from natural resources such as stems of plants. In contrast to synthetic fibers (e.g., carbon fibers), natural fibers are from renewable resources and are eco-friendlier. Plant fibers are important members of natural fibers. Review papers discussing the microstructures, performances and applications of natural plant fiber composites are available in the literature. However, there are relatively fewer review reports focusing on the modeling of the mechanical properties of plant fiber composites. The microstructures and mechanical behavior of plant fiber composites are briefly introduced by highlighting their characteristics that need to be considered prior to modeling. Numerical works that have already been carried out are discussed and summarized. Unlike synthetic fibers, natural plant fiber composites have not received sufficient attention in terms of numerical simulations. Existing technical challenges in this subject are summarized to provide potential opportunities for future research.

“…It is evident that the components of composites tend to decrease the molecular mobility (Ariawan et al 2015). Additionally, the gradual decrease in the Eʹ as the temperature increased indicated the highly crosslinked density of the composites, which meant a tighter network structure and higher stiffness (Saba et al 2016a;Duc et al 2014). This was due to the fact that the chain motions were perturbed in the immediate vicinity of the cross-links (Sreekala et al 2005).…”

“…The reinforcement of vinyl ester with jute fibre increases Eˊ values of the composites as a result of more interfacial stress transfer. In a different study, the DMA properties of natural flax fibre reinforced polypropylene, polylactic acid (PLA), and epoxy composites were found to be better than those of carbon and glass composites (Duc et al 2014). The best compromise between stiffness and damping was reported in the case of flax fibre reinforced in semi-crystalline biodegradable PLA.…”

,ePhenolic-based sugar palm fibres (SPFs) were used as a filler for composites that were fabricated by hot pressing. The composites were prepared using various volume loadings of SPFs. Dynamic mechanical analysis (DMA) was carried out to evaluate the storage modulus (Eʹ), loss modulus (Eʺ), and tan delta as a function of temperature. The SPFs were treated by seawater for 30 days and a 0.5 alkaline solution for 4 days. The phenolic composites with 30% volume loading of SPFs were used to determine the effect of treatments on the DMA properties of the composites. The obtained results indicate that incorporating a SPF filler notably increased the Eʹ and Eʺ properties and decreased the damping factor of the phenolic composites. Both treatments affected the DMA results. However, the alkaline-treated composites showed higher DMA properties compared with the seawater-treated and untreated fibre composites.

“…Apart from wet-impregnation [8,12,28], NFRP composites based upon thermosetting matrices have been successfully processed via the relatively inexpensive infusiontype manufacturing methods such as resin infusion under flexible-tooling (RIFT) [10,22,29] or closed mould resintransfer moulding [12,18,20]. Although moisture in natural fibres, present when the NFRP composite is manufactured, is generally considered to be detrimental to the fibre-matrix interface adhesion, drying the fibres prior to infusion has not been conventionally practised.…”

“…The exciting potential of NFRP composites based upon textile-woven fibres and employing thermosetting polymeric matrices has encouraged efforts to provide data on other engineering properties such as fatigue [8][9][10], compression [11], damping [12], fracture toughness [13][14][15], impact [16,17], and thermal/flammability [7,18] properties. The effects of various types of fibre architecture, such as the weave form, lay-up, and mixtures of fibre types [10,11,13,19], have also been reported.…”

Tough, natural-fibre composites based upon epoxy matrices

et al. 2015

Flax fibres and cellulose fibres were used to manufacture composites with particle-modified epoxy matrices in order to develop 'green' composites which possess relatively high values of interlaminar fracture energy, G c . The flax used had a unidirectional architecture of continuous yarns spun from short, interlocked fibres. The regenerated cellulose consisted of continuous and nontwisted pure cellulose fibres in a plain-woven architecture. The natural-fibre-reinforced-polymer (NFRP) composites employed an anhydride-cured diglycidyl ether of bisphenol-A epoxy as the matrix. The epoxy polymeric matrix was modified with (a) silica nanoparticles, (b) rubber microparticles, and (c) a combination of both of these types of particles to give a hybrid-toughened epoxy matrix. The composites were manufactured via a resin infusion under flexible-tooling (RIFT) process. Preliminary studies on the NFRP composites manufactured using the initial-RIFT process clearly showed the deleterious effect that moisture present in the natural fibres had upon the properties of the NFRP composites, since the trapped water cannot escape from the composite panel. Hence, an optimised-RIFT process was developed whereby the natural fibres were dried in a fan oven prior to being employed in the RIFT process. This reduced the water content of the fibres from around 9 to 10 wt% to about 1 wt%. Significant improvements in the physical and mechanical properties were recorded for the NFRP composites manufactured using this optimised-RIFT process. Indeed, in particular, very dramatic improvements in the G c of the NFRP composites were measured, especially when the epoxy polymeric matrix was modified using the silica nanoparticles and/or rubber microparticles. For example, a steady-state propagation value of G c of about 1935 J/m 2 was measured for the flax-fibre composite with the hybrid epoxy matrix, compared to values of 1110 and 535 J/m 2 for the flax-fibre and glass-fibre composites based on the unmodified (i.e., the 'control') epoxy matrix, respectively.
