“…The most common polyethylene types are low-density polyethylene (LDPE) and high-density polyethylene (HDPE). LDPE provides several advantages in the automotive industry such as fuel savings, chemical resistance, ease of processing, corrosion resistance, and electrical insulation, as reported in a previous study [ 30 ]. However, the use of recycled LDPE (rLDPE) as a polymer matrix for producing reinforced composites can be a serious environmental problem owing to the non-biodegradable properties of LDPE.…”

The search for renewable alternatives for petroleum products that can be used in industrial applications is increasing. Each year, several tons of bio-derived industrial waste is produced and most of it is burned or placed in landfills. Olive pits (OP) have unique characteristics such as abundance, renewability, and biodegradability, which can be utilized to develop new types of biocomposites. One of the most promising uses of OP is that they can reinforce the mechanical properties of polymeric biocomposites. This study describes the preparation of recycled low-density polyethylene (rLDPE) that is filled with OP flour (10, 20, 30, and 40 wt.%) using a twin-screw extruder. The effects of the chemical treatment of the OP surface (sodium hydroxide (NaOH) and dimethyl sulfoxide (DMSO)) on the bio-filler/polymer compatibility along with the produced composite’s chemical, physical, mechanical, and thermal properties have been explored. Overall, the reinforced composites that were obtained with alkali-treated OP have better biocomposite properties. This indicates an improved compatibility between the bio-filler and matrix. The results are promising in terms of using OP flour in developing green composites.

In this study, poly(lactic acid) (PLA)/pistachio shell (PS) biocomposites were fabricated by melt functionalization through a one-step compatibilization process in varying PS filler rates (0–30%). To enhance interfacial adhesion, alkaline-silane pre-treatment was applied to PS, and PLA was grafted with maleic anhydride (MA). The effect of filler ratio, pre-treatment, and maleation steps on the mechanical, thermal, and morphological properties of biocomposites was investigated. The tensile and flexural analysis showed that composites with optimum mechanical properties were obtained by blending 20% of pre-treated PS with maleated PLA. Mechanic and thermal analyses were performed to examine fiber/matrix surface compatibility. The mechanical analysis of biocomposites, such as tensile/flexural strength and modulus were determined with a universal testing machine. Thermal analysis and thermal degradation of biocomposites were determined by using Differential Scanning Calorimetry and TG/DTG. Morphological analysis performed by SEM proved that the composites prepared by maleated PLA and pre-treated PS showed better adhesion between the fiber and the matrix.

“…The reason for this might be explained by the fact that a higher amount of fiber reinforcement improves the interfacial strength properties but not the impact resistance of the composite [34,35]. The impact resistance of the fiber-reinforced composites is generally affiliated with the specific properties of the fiber and resin system, the amount of impact energy conveyed to the composite sample, and the interface properties of the fiber/matrix system [36][37][38]. The effect mechanism of the fiber material amount on the impact resistance of textile reinforced composites is more sophisticated than tensile and flexural strengths properties due to the impact resistance of energy distribution during stress.…”

Braiding technique is one of the most cost-effective and versatile methods to manufacture braided preforms for producing textile reinforced composites which have been utilized in a number of applications such as aerospace and automotive sectors. Carbon fiber is one of the most common reinforcing fibers having high strength and modulus used in high-performance composites. In this study, epoxy resin was modified with 3 – aminopropyltriethoxysilane (APTES) and 3 – aminopropylmethyldimethoxysilane (APMDMS) in order to enhance interfacial adhesion between matrix and carbon fiber. Composites were produced by vacuum-assisted resin infusion method (VARIM) using braided carbon fabrics and epoxy resin which was treated with silane at different concentrations (from 0.0% to 1.0%). Braided fabrics were manufactured from a high-strength standard modulus type of carbon fiber and using a radial braiding machine. According to the mechanical results, the ideal (optimum) concentration of APTES and APMDMS for the matrix modification has been around 0.5 wt% of the epoxy system. Also, the mechanical properties of APTES-treated epoxy composites are slightly higher than those of APMDMS-treated epoxy composites at the same concentration. When it is compared to silane untreated composite, 0.5 wt% of APTES/APMDMS silane treated epoxy/carbon braided composites have led to an increase of 7.71/6.16 and 7.65/6.05 % in tensile and flexural strength while the corresponding increase has resulted in 17.48/13.51 and 16.63/13.33 % in terms of tensile and flexural modulus, respectively. Impact testing results indicate that 0.5 wt% of APTES and APMDMS composites are improved 6.87 and 4.31 % compared to untreated composites, respectively.
