“…Because the sisal and coconut powders have lower flexural strengths than the matrix, in this case, as a result, the composite specimens' flexural strength is reduced, where the composite flexural strength weakens as the percentage of coconut content rises [33]. Also, the composite flexural strength decreases with increasing the sisal powder's weight fraction [34]. Additionally, Figures 9 and 10 elucidate that the specimens' flexural strength values when sisal powder is added are higher than those for flexural strength when coconut powder is added.…”

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.

“…Figure 10 and Figure 11 reveal the relation between the weight fraction of sisal and coconut powder for each of the 2% PA-PMMA and 2% PVP-PMMA blend matrices and the tensile strength of composite specimens, respectively, where the tensile strength values for these matrices dropped when the content of sisal and coconut powders was increased. This phenomenon is attributed to the fact that sisal and coconut powders possess lower tensile strengths compared to the blend matrix, and it is further compounded by the occurrence of agglomeration within the matrices [29,30]. Thus, the lower value of tensile strength is 73 MPa for 2% PVP-PMMA-6% coconut composite material.…”

Removable complete dentures are still a therapy of choice for a variety of medical professionals and patients even in an era of implant and fix prostheses. This article focuses on comparing complete dentures manufactured using various denture base materials. Heat-cured polymethylmethacrylate, used for prosthetic complete denture composites, was blended separately with Polyamide (PA) type 6 and Polyvinylpyrrolidone (PVP) type K30. These blends were prepared with various weight fractions (0%, 2%, 4%, and 6%) and reinforced with sisal and coconut powders, each added individually with varying weight fractions (2%, 4%, and 6%). The tensile test was carried out to achieve tensile strength, modulus of elasticity, and elongation percentage values. The numerical part depends on the Finite Element Method (FEM), conducted by using Ansys Workbench-2020 R2. According to the experimental data, the tensile strength, elastic modulus, and elongation of polymer blends increase at a 2% weight fraction of PA and PVP particles, and then decrease with higher PA and PVP particles' weight fraction. However, they decrease with increasing weight fraction of coconut and sisal particles. The highest tensile strength and elastic modulus are 86 MPa and 2.531 GPa, respectively, for PMMA-2% PA, and the greatest elongation percentage is 5.28% for PMMA-2% PVP. These findings lead to the conclusion that the addition of polymer blend materials to PMMA resin is a promising approach for improving tensile properties in applications such as complete or partial denture bases, addressing an ongoing challenge.

The current work aims to investigate the mechanical properties of rare oxide reinforced Mg alloy based MMCs. Magnesium matrix considered in the study is AZ91D alloy, whereas rare earth oxides reinforced were CeO2 and Y2O3. The Y2O3 particulate reinforcement percentage was varied from 1 to 3% in the steps of 1% to study its influence on mechanical properties of MMCs. Stir casting route was adopted to fabricate sample for study. Microstructure analysis illustrated the uniform distribution of particulate in matrix alloys. The obtained results revealed the enhanced mechanical properties such as tensile strength, yield strength, elongation and hardness of MMCs due to increased percentage of reinforcement. Fractography analysis of fracture surfaces demonstrated the microcracks and cleavage were dominant in pure alloy. While particle debonding, extensive plastics deformation were prominent in-addition to microcracks in MMCs.
