“…The physical–chemical compositions of OHF and PPSF were determined according to Klaai et al. [ 16 ] Prior to the chemical analysis for cellulose, hemicellulose, and lignin, the flours samples were oven‐dried at 105°C for at least 4 h and kept in a desiccator.…”

“…Several studies showed that for composites of PLA and natural fibers, mechanical properties, namely, tensile and flexural moduli, increased due to natural fiber addition. Klaai et al [16] indicate that the increase in the prickly pear seed fiber (PPSF) content from 0% to 20% (by weight) increased Young's modulus, while it gradually decreases the tensile strength and the elongation at break for the elaborated composites (PLA/PPSF). According to Barczewski et al, [17] the tensile strength decreased from 69 MPa (pure PLA) to 40.8 MPa for composite filled with 30 wt% of chestnut shell (CN), elongation at break value determined for pure PLA, equal to 4.8%, decreased to 1.5% for highest CN content.…”

Currently, food waste is a major concern for businesses, governments, and consumers. Fruit processing creates many of by‐products, from undesirables to fruit skins, seeds, and fleshy parts. These by‐products make up to 30% of the initial mass of processed fruit. This goal can be achieved by transforming fruit waste into reinforcement and integrating it into polymeric materials. In this work, olive husk flours (OHF) and prickly pear seed flours (PPSF) are used as reinforcements of poly (lactic acid) (PLA) matrix. Initially, the physico‐chemical, particle size, spectroscopy (FTIR), and thermal characterization of its fibers are studied and compared. Then, the composite materials studied are manufactured with a twin‐screw extruder having a fiber content of 10%, 20%, and 30% by weight; its properties have been studied and compared. The characterization of these two fibers shows that the quantity of cellulose is greater in the OHF and that the latter is more thermally stable. For the composite material, the PLA /OHF are the most responsive in thermal and mechanical behaviors since their degradation temperatures are closer to pure PLA and the tensile modulus is higher compared to the PLA/PPSF composites. The equilibrium water uptake value is higher for composites reinforced with OHF than systems with PPSF.

“…The author noticed that cactus/polyester composites exhibit a substantially greater flexural modulus than their tensile counterparts, as well as good energy dissipated per unit volume over low cycles and high loading levels. Similarly, Klaai et al 7 studied the use of prickly pear seed fibers as reinforcement in polylactic acid biocomposites. Spectroscopic (FTIR), thermal, morphological, and mechanical characterizations, as well as water absorption tests, were performed and compared.…”

In this research, the role of prickly pear short fiber and red onion peel wrinkled biocarbon nanosheets toughened epoxy resin composite was investigated. The main aim of this research was to find the effectiveness of adding biocarbon along with prickly pear fiber in the load‐bearing, thermal and electrical conductivity behavior of the epoxy resin composite. The biocarbon nanosheets were prepared for this present investigation from red onion peel waste using the pyrolysis process. The composites were characterized by American society of testing and materials (ASTM) standards and compared with previous results. The highest tensile strength and flexural strength were observed for 3 vol.% of biocarbon nanosheets up to 60% and 40% respectively than pure epoxy. Izod impact toughness and hardness values also increased with the inclusion of reinforcements by 5 vol.% around 93% and 90% correspondingly. Similarly, relative permittivity and dielectric loss enhanced about to 6.4 and 0.74 for 5 vol.% of biocarbon nanosheets. The thermal conductivity also improved with the addition of biocarbon nanosheets and maximum values up to 0.42 W/mK. This enhanced dielectric, mechanical, and thermally active composites might be employed as a microwave shielding material in electronic devices, automotive, and industrial applications for communications equipment that require shielding material with good mechanical properties.
