“…In [66] similar (UD and woven specimens, P(St-co-GMA) nanofibers) but only minor improvements have been found: their open holed specimens' tensile strength registered a tensile strength 5% higher than that of the control sample. In [22] and [60], samples are tested under tensile-tensile fatigue loads, and present very similar improvements: nanomodified samples had 10 to 30 and 3 to 50 times longer lives, respectively. Three works in literature have been found dealing with tensile properties of nanomodified GFRP laminates, and they do not show the same agreement registered for carbon fibers.…”

“…The most used polymer is the PVA, and tests on carbon fibers present a very close range of results: [22] (PW laminates), [59] (UD laminates), and [60] (PW CF/VE composites), where 12, 9, and 11% improvement in tensile strength have been reported, respectively. In [66] similar (UD and woven specimens, P(St-co-GMA) nanofibers) but only minor improvements have been found: their open holed specimens' tensile strength registered a tensile strength 5% higher than that of the control sample.…”

“…• resin reinforcement [23,60,[87][88][89][90][91][92][93][94], detected by several authors, using a different type of polymers. In [94] it is demonstrated that using an hybrid electrospinning-electrospraying method (electrospraying uses polymers with much shorter chains which end deposited as particles rather than fibers), a resin containing 0.13% weight content of fiber was 700% stronger, 250% stiffer, and more ductile than the non-modified one.…”

“…The main issues with the use of CNT and CNF are linked to health dangerousness [85] and difficulties in mixing and homogenizing with the matrix [86]. Authors considered out of the scope of this literature, and therefore did not treat, studies on nanofibers embedded in pure matrix [60,[87][88][89][90][91][92][93][94], on the single nanofiber [95][96][97][98], and on numerical simulations of nanomodified composites [65,[99][100][101][102].…”

In the last few decades nanofibers have been developed and introduced in a vast number of industrial and research applications. One of their most effective use is as interleaved reinforcement for composite laminate materials against delamination. Nanofibrous mats have the ideal morphology to be embedded between two plies of a laminate, and a vast and deep research has been carried out investigating their effect on the global behaviour of a composite laminate. This review is the first of its kind to date which presents a detailed state-ofthe-art on the effect of nanofibrous interleaves into composite laminates with focus on the mechanical performances and behaviours of nanomodified materials. A detailed description of the working mechanisms of the nanointerleave under different load cases is presented, and a comparative analysis between papers in literature will provide readers with a powerful tool to understand and use nanofibers for reinforcing purposes.

“…The CNF can be used in drug release and energy storage applications, due to its nanostructure (Dima et al 2016;Pan et al 2016). It can also be mixed with other materials and made into composites, due to its strong mechanical properties and web-like network that can improve the interfacial adhesion (Shao et al 2015;Barari et al 2016a;Barari et al 2016b). The CNF could be a great candidate to produce binderless particleboard.…”

Wet-formed particleboard bonded with cellulose nanofibrils (CNF) was prepared in this work. The effects of density, CNF addition ratio, pressing method, and particle size on the bending strength were evaluated. The results showed that density had the most important effect on the modulus of elasticity (MOE), while the CNF addition ratio had the most important effect on the modulus of rupture (MOR). For panels with low density (< 640 kg/m 3 ), the MOE and MOR did not change much with the configuration changes between particle size and pressing method. This was due to the synergistic effect of incomplete compression and poor bonding in the core area using a constant thickness (CT) pressing method, and lower face density and higher core density using a constant pressure (CP) pressing method. For panels with medium density (640 kg/m 3 to 800 kg/m 3 ), the combination of larger particles, higher CNF addition ratio, and CT pressing method contributed to the highest bending strength. Further increase to high density (> 800 kg/m 3 ), the pressing method's effect was more important, compared to panels with low and medium densities. With increased density and CNF addition ratio, panels were able to meet lowdensity and some medium-density standard MOE and MOR requirements.

Cellulose microcrystal improved interphase of ramie fiber‐reinforced epoxy resin composites

et al. 2017

This article investigated the effect of cellulose microcrystal (CMC) and low molecular polyamide (PA650) on the mechanical and water absorption properties of ramie fiber‐reinforced epoxy composites. Results showed that coating mixture of CMC and PA650 (CMC/PA650) on the surface of ramie fiber improved the interfacial adhesion strength of ramie fiber/epoxy composites. As a result, the flexural strength, flexural modulus, and interlaminar shear strength of PA650/CMC‐coated ramie fabric‐reinforced epoxy composites (CPRFC) were 10.6%, 8.1%, and 7.4% higher than those of ramie fabric without coating reinforced epoxy composites (RFC). Additionally, saturated water absorption of CPRFC was reduced by 40.5% and 31.5% than that of RFC and PRFC, it seems that a water‐resistant interphase exists in the CPRFC and it is more efficient at the early stage of water immersion. However, without filling of CMC in PA650, lowest flexural modulus and highest flexural strain of the composites were found. POLYM. COMPOS., 39:E2207–E2216, 2018. © 2017 Society of Plastics Engineers
