“…The decrease in the RCF-reinforced modulus was much larger due to the aging compared to the raw material ones. A decreasing Young´s modulus because of moisture absorption due to high humidity or because of increased temperatures have also been seen in the studies by Arif et al [ 42 ] and Basso et al [ 10 ]. Both studies have shown a correlation of cracks and damages with aging and the fracture behavior, resulting in a lower Young’s modulus and tensile strength.…”

“…Several studies have already examined cellulose fiber-reinforced bio-based polyamides, e.g., PA4.10, PA6.10, PA10.10, and PA11. They have shown significant increases in all mechanical properties, especially that the notched impact strength increases depending on the fiber content [ 10 , 11 , 12 ]. In addition, the relationship between the fiber-matrix adhesion and the mechanical properties has also been addressed in different studies [ 13 , 14 , 15 , 16 ].…”

With regard to the sustainability and biological origin of plastic components, regenerated cellulose fiber (RCF)-reinforced polymers are expected to replace other composites in the future. For use under severe conditions, for example, as a housing in the engine compartment, the resistance of the composites and the impact on the fiber and fiber-matrix adhesion must be investigated. Composites of bio-polyamide with a reinforcement of 20 wt.% RCF were compounded using a twin-screw extruder. The test specimens were manufactured with an injection molding machine and aged under conditions of high humidity at 90% r. H, a high temperature of 70 °C, and water storage using a water temperature of 23 °C for 504 h. Mechanical tests, single-fiber tensile tests (SFTT), single-fibre pull-out tests (SFPT), and optical characterization revealed significant changes in the properties of the composites. The results of the SFPT show that accelerated aging had a significant effect on the bio-polymer and an even stronger effect on the fiber, as the single-fiber tensile strength decreased by 27.5%. Supplementary notched impact strength tests revealed a correlation of the impact strength and the accelerated aging of the RCF-reinforced composites. In addition, it could be verified that the tensile strength also decreased at about 37% due to the aging effect on the RCF and a lowered fiber-matrix adhesion. The largest aging impact was on the Young’s modulus with a decrease of 45% due to the accelerated aging. In summary, the results show that the strengthening effect with 20 wt.% RCF was highly decreased subsequent to the accelerated aging due to hydrolysis and debonding because of the shrinkage and swelling of the matrix and fiber. These scientific findings are essential, as it is important to ensure that this bio-based material used in the automotive sector can withstand these stresses without severe degradation. This study provides information about the aging behavior of RCF-reinforced bio-based polyamide, which provides fundamental insights for future research.

“…The nylon 6,6 with 50 wt.% glass fibre reinforcement represent high tensile strengths and elastic modulus. The highest value of strength and modulus were perceived for the glass fibre composites, attributable to higher strength, stiffness, better interfacial bonding of glass fibre (Basso et al, 2019;Mortazavian and Fatemi, 2015).…”

The aim of this study is to enhance the tensile and flexural strength of polyamide (nylon 6, 6) by incorporation of glass fibre. Nylon has high elasticity, strength, toughness and maintain mechanical properties at elevated temperatures. The method employed for enhancement of properties is by the reinforcement of glass fibre. Glass fibre is the most extensively used reinforcement material. It is a lightweight, extremely solid, durable, low cost material that moderafly stiff. The composition of glass fibre was kept at 0 wt.%, 30 wt.% and 50 wt.% in nylon 6,6 blend. Initially, samples were manufactured by injection molding of nylon 6,6 and glass fibre. The pressure and velocity profiles at 0 wt.%, 30 wt.% and 50 wt.% reinforced nylon 6,6 are also compared. The samples thus formed were checked for shrinkage. The samples were tested for their tensile and flexural properties. The mechanical properties of polyamide (nylon 6,6) significantly improves by increasing glass fibre reinforcement.
