“…Meanwhile, the flexural modulus of PBAT/ WBL composites and PBS/WBL composites increased from 360 to 534 MPa and 569 to 779 MPa, respectively, as the loading of WBL increased from 5 wt% to 15 wt%. This is due to the high stiffness of the fibers compared to the matrices [25][26][27]. This finding suggests that WBL fiber influences flexural strength.…”

Wet blue leather is a waste produced by the leather industry. It is a difficult waste product to dispose of, and if not disposed of properly, it will affect the environment and cause toxicity. Therefore, recycling was considered as an alternative to waste disposal. In this study, polymer composites were prepared from two types of polymers, poly(butylene adipate-co-terephthalate) (PBAT) and poly(butylene succinate) (PBS), and wet blue leather (WBL). A twin screw extruder and injection molding were used to prepare the composites. The effect of polymer type and WBL content (5, 10, and 15 wt%) on mechanical properties, thermal properties, flammability, MFI, water absorption, and morphology was investigated. All the polymer composites showed an increase in tensile and flexural strength, Young’s modulus, and water absorption but decreased in elongation at break, impact strength, and flammability compared to neat polymers.

“…Additionally, the natural fibers' inherent flexibility can be harnessed to produce sockets that allow for a more natural range of motion, enhancing the overall comfort and usability for the end user. The ability to customize the mechanical properties of NFRP based on the type and proportion of natural fibers used allows for a high degree of adaptability to diverse prosthetic needs [18].…”

This review systematically examines the burgeoning field of natural fiber-reinforced polymer (NFRP) composites in prosthetic socket fabrication. The review begins by exploring the historical context and recent shift towards sustainable and biocompatible materials in prosthetics, with a specific focus on NFRP. It delves into the composition and properties of NFRP, detailing the types of natural fibers used and the characteristics of these innovative composites. The review highlights the advantages of NFRP in prosthetics, notably their biocompatibility, sustainability, and mechanical properties that are pertinent to prosthetic applications. The technical aspects of fabricating prosthetic sockets with NFRP are examined, discussing both traditional and advanced manufacturing techniques and design considerations that take into account anatomical and biomechanical factors, as well as the need for customization. The clinical outcomes and user experiences with NFRP prosthetic sockets are evaluated, focusing on their durability, functionality, and comparison with traditional materials. User-centric perspectives, including comfort, satisfaction, and adaptation challenges, are also considered. Crucial challenges and limitations in the field are identified, such as technical and fabrication complexities, consistency and quality control issues, as well as clinical and practical barriers like accessibility, cost, and the necessity for specialized training. The review outlines future directions and research needs, emphasizing potential innovations in NFRP, integration with emerging technologies, and the importance of translational research and interdisciplinary collaboration. The review underscores the significant role NFRP could play in advancing prosthetic technology, envisioning a future where prosthetic design is not only user-friendly and functional but also sustainable

“…The whole measured data from a 3point bending test device was obtained at room temperature (25 ± 2℃) and the number of specimens used in this test is (5) via utilizing a hydraulic press (Type Leybold Harris No. 36110) employing a short beam as well as applying gradually a load till the occurrence of specimen fracture [31]. Figure 7 shows the standard specimen of the maximum shear strength test and the specimens before and after the maximum shear strength test [32].…”

By blending heat-cured polymethylmethacrylate (PMMA) resin with two different types of polymers, which are polyamide (PV) type ( 6) and polyvinylpyrrolidone (PVP) type (K30), added separately with various weight fractions (0, 2, 4 and 6%) to heat-cured PMMA resin as blend matrix, attempts have been made in this study for developing the PMMA resin properties employed for prosthesis complete denture. Sisal powder and coconut powder, two different types of natural powders, were added separately to the polymer blend matrices with varying weight fractions (2%, 4%, and 6%) to prepare composite specimens. Hand lay-up methods were used for preparing all specimens. This study covered the flexural test using the 3-point bending method, the impact test using the Izod method, and the maximum shear stress test using the 3-point bending method.According to the results, adding polymer blends and reinforcing powders boosts the impact strength, while lowering flexural modulus, flexural strength, and maximum shear stress. The composite specimens made of (PMMA-2% PVP-6% sisal) manifested the best impact strength and value (11.875 KJ/m 2 ). These findings lead to the conclusion that using PMMA-based biocomposites with polyamide and polyvinylpyrrolidone blends improved impact strength for denture applications, which is one of the most important properties of these applications.
