“…This is due to the low thermal stability of the lignocellulosic reinforcement, whose degradation onset temperature begins around 234 °C, which affects the overall thermal stability of composites negatively. Besides, the increased filler content in composites results in a reduced weight fraction of the BioEP resin, causing a more significant decrease in T0 as the filler content increases [20]. As shown in Figure 4a, the FF showed four typical degradation stages of lignocellulosic materials.…”

“…Different contents (10,20,30, and 40 wt%) of CFF and FFF were added to the liquid epoxy resin Resoltech ® 1070 ECO and were mixed at room temperature in a planetary mixer KAPL 5KPM5 from KitchenAid (Benton Harbor, MI, USA) with a total volume of 4.8 L. First, the FF was added to the mixer with the biobased resin and was subjected to initial homogenization at 40 rpm for 5 min. Then, Resoltech ® 1074 ECO hardener was added in the stoichiometric ratio (100:35 wt/wt) to the BioEP/FF mixture and subjected to a second mixing cycle at 60 rpm for 2.5 min.…”

“…As expected, the lowest flexural strength is obtained in composites reinforced with 40 wt% of CFF and FFF, obtaining a flexural strength of 22.5 and 22.9 MPa, respectively, which represents a decrease of 76.4% and 75.9% in comparison to the flexural strength of the unfilled BioEP resin (95.2 MPa). This decrease in flexural strength is due to the lack of adhesion between the lignocellulosic filler and the surrounding matrix, which causes stress concentration phenomena that promote breakage [20]. Another issue with a high influence on the mechanical properties of composites is the filler aspect ratio.…”

“…There are many research works that have focused on the effect of different types of lignocellulosic particles on the properties of both thermoplastic and thermoset matrices. For example, interesting works have been developed with rice husks [9][10][11], peanut shells [7,12,13], almond shells [14][15][16], hazelnut shells [17,18], date palm seeds [19], lemon peel [20], Posidonia oceanica [21,22], olive stones [23], among others. Most of these lignocellulosic particles come from agricultural by-products or wastes that are currently used for animal feeding and just left on controlled landfills.…”

“…Specifically, the effect of particle size and the content of flaxseed flour on the mechanical, morphological, thermal, and water absorption properties of the bioepoxy/flaxseed flour composites, has been investigated. In the present work, four compositions (10,20,30, and 40 wt%) and two-particle sizes (CFF and FFF) were investigated.…”

In the present work, green-composites from a partially biobased epoxy resin (BioEP) reinforced with lignocellulosic particles, obtained from flax industry by-products or wastes, have been manufactured by casting. In this study, the flaxseed has been crushed by two different mechanical milling processes to achieve different particle sizes, namely coarse size (CFF), and fine size (FFF) particle flaxseed flour, with a particle size ranging between 100–220 µm and 40–140 µm respectively. Subsequently, different loadings of each particle size (10, 20, 30, and 40 wt%) were mixed with the BioEP resin and poured into a mold and subjected to a curing cycle to obtain solid samples for mechanical, thermal, water absorption, and morphological characterization. The main aim of this research was to study the effect of the particle size and its content on the overall properties of composites with BioEP. The results show that the best mechanical properties were obtained for composites with a low reinforcement content (10 wt%) and with the finest particle size (FFF) due to a better dispersion into the matrix, and a better polymer-particle interaction too. This also resulted in a lower water absorption capacity due to the presence of fewer voids in the developed composites. Therefore, this study shows the feasibility of using flax wastes from the seeds as a filler in highly environmentally friendly composites with a wood-like appearance with potential use in furniture or automotive sectors.

The production of degradable packaging materials is a task that can be no longer postponed. Moreover, high amounts of agricultural wastes are landfilled without any recycling. In this research, the possibility to formulate particulate composites made of biopolymers filled with coffee waste with acceptable physical and mechanical characteristics that will degrade is investigated. The addition of this agricultural waste, by reducing the requested amount of biopolymer, can decrease the overall price of the material presently the main limiting factor to the use of biopolymers in the packaging industry. Silverskin, the integument of coffee beans discarded during the roasting process, after a milling step, is added up to a 30 wt% either to polylactic acid (PLA) or to a blend of PLA and polybutylene succinate. The filler can be homogeneously dispersed in both systems. The data shows that the silverskin filler increases the elastic modulus but decreases the tensile strength of the material and helps the development of crystal phase in the matrix. The thermal stability and the hydrophobicity of the materials stay almost unchanged on filler addition. Moreover, data shows that the addition of silverskin increases the materials susceptibility to microbial attack.

Development of sustainable and lighter‐weight materials with low or zero carbon footprint is the major research field in 21st century. The current research has been focused on the development of hybrid composite materials from organic wood particles and graphene nanoparticles (GNPs) along with epoxy resin as matrix material. A constant 5% weight percentage of wood particles has been maintained, while GNPs weight percentages have been varied from 0% to 1% by weight with an equal interval of 0.25. The effects of GNPs addition on wood particle reinforced epoxy composite have been examined by performing different structural, physical, mechanical, thermal, and dynamic mechanical testings. The addition of GNPs up to 0.75% resulted in the increment of 28% hardness, 42.04% tensile strength, 34.24% flexural strength, 22.47% impact strength, and 16.3% fracture toughness, and 129.61% conductivity compared with wood composites (GPC‐0.0). Similar observations have been observed for dynamic mechanical analysis where, the GPC‐0.75 composites recorded maximum storage modulus (2.54 GPa), viscous modulus (0.27 GPa), and glass transition temperature (97°C). Further increments of graphene percentage (GPC‐1.0) resulted in agglomeration between particles and revealed decrements properties. The structural analysis of wood particles and GNPs have been examined with X‐ray diffractometer, Fourier transforms infrared spectroscopy, and thermogravimetric analysis. The developed composites showed better interfacial bonds between matrix and reinforcements that reduce the void and moisture contents as well as improved the fracture behavior. Therefore, these filter‐hybrid composites may be used for energy harvesting, solar cells, electronic gadgets, sensor, and heating equipment.
