“…Before considering the use of graphene-base materials, the application of NLFs as reinforcement of polymer matrix composites for ballistic protection was investigated [ 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 158 , 159 , 160 , 161 , 162 ]. The ballistic performance of these composites was found to be in the same order of magnitude of commonly used materials such as Kevlar TM and Twaron TM , which are aramid-based fibers, or Dyneema TM and Spectra TM , produced with UHMWPE.…”

A novel class of graphene-based materials incorporated into natural lignocellulosic fiber (NLF) polymer composites is surging since 2011. The present overview is the first attempt to compile achievements regarding this novel class of composites both in terms of technical and scientific researches as well as development of innovative products. A brief description of the graphene nature and its recent isolation from graphite is initially presented together with the processing of its main derivatives. In particular, graphene-based materials, such as nanographene (NG), exfoliated graphene/graphite nanoplatelet (GNP), graphene oxide (GO) and reduced graphene oxide (rGO), as well as other carbon-based nanomaterials, such as carbon nanotube (CNT), are effectively being incorporated into NLF composites. Their disclosed superior mechanical, thermal, electrical, and ballistic properties are discussed in specific publications. Interfacial shear strength of 575 MPa and tensile strength of 379 MPa were attained in 1 wt % GO-jute fiber and 0.75 wt % jute fiber, respectively, epoxy composites. Moreover, a Young’s modulus of 44.4 GPa was reported for 0.75 wt % GO-jute fiber composite. An important point of interest concerning this incorporation is the fact that the amphiphilic character of graphene allows a better way to enhance the interfacial adhesion between hydrophilic NLF and hydrophobic polymer matrix. As indicated in this overview, two basic incorporation strategies have so far been adopted. In the first, NG, GNP, GO, rGO and CNT are used as hybrid filler together with NLF to reinforce polymer composites. The second one starts with GO or rGO as a coating to functionalize molecular bonding with NLF, which is then added into a polymeric matrix. Both strategies are contributing to develop innovative products for energy storage, drug release, biosensor, functional electronic clothes, medical implants, and armor for ballistic protection. As such, this first overview intends to provide a critical assessment of a surging class of composite materials and unveil successful development associated with graphene incorporated NLF polymer composites.

“…In particular, a new trend for designing “greener materials” made of natural lignocellulosic fibers (NLFs) is revealing potential materials for the reinforcement of composites for engineering applications [ 4 , 5 , 6 , 7 , 8 ]. Indeed, several NLF-reinforced polymer matrix composites exhibit promising results in different industries, such as the automobile [ 9 , 10 ], aerospace [ 11 ], packing [ 12 ], and building [ 13 , 14 , 15 ] industries, as well as, more recently, even as impact-resistant materials for use against high-energy ammunition [ 16 , 17 , 18 , 19 , 20 ].…”

Fibers extracted from Amazonian plants that have traditionally been used by local communities to produce simple items such as ropes, nets, and rugs, are now recognized as promising composite reinforcements. This is the case for guaruman (Ischinosiphon körn) fiber, which was recently found to present potential mechanical and ballistic properties as 30 vol% reinforcement of epoxy composites. To complement these properties, Izod impact tests are now communicated in this brief report for similar composites with up to 30 vol% of guaruman fibers. A substantial increase in impact resistance, with over than 20 times the absorbed energy for the 30 vol% guaruman fiber composite, was obtained in comparison to neat epoxy. These results were statistically validated by Weibull analysis, ANOVA, and Tukey’s test. Scanning electron microscopy analysis disclosed the mechanisms responsible for the impact performance of the guaruman fiber composites.

Different materials require specific test-piece dimensions and designations for their mechanical characterization, present either in ASTM, ISO, or DIN norms. Natural polymers or bio-fibers are materials that have lignocellulosic fibrils that can be mechanically characterized as single fibers, which tend to be bundles of thinner hollow fibrils. In this work, a new approach has been applied to the unique natural fiber Luffa cylindrica, also called loofah or scourer, as loofah dumbbell test-pieces (LDTs) similar in length to the Type IV ASTM D-638 samples for unreinforced or reinforced plastics. 60 LDTs of 120 mm and 40 mm in length and width respectively were cut by hand, with and without alkali treatment (aqueous 2%NaOH), in transversal and longitudinal directions, to be characterized using testing speeds of 1 mm/min and 50 mm/min, SEM, XRD, statistics, and Weibull analysis. The resultant force vs. elongation/stress vs. strain graphs revealed a high variability of LDTs, and mercerization was found to increase their mechanical resistance. SEM images confirmed a microtubular cellular structure, XRD exposed an increment in crystallinity after alkali treatment, and Weibull indicated the probability of failure in 10 samples per configuration.
