Abstract
This research is studying the effect of reinforcement the acrylic resin (PMMA) by two types of nanoparticles, which included: Walnut shell (WSP) and Talc particles (TP) that practical sizes are (40.8 and 29.2 nm) in individually form, and utilize at three various concentrations (0.1, 0.2 and 0.3wt.%), to improve in the mechanical properties of composite materials. The results showed that the Tensile and Hardness shore D properties became better with increasing the concentration of nanoparticles. The highest value of (tensile strength, modulus of elasticity and elongation at break) was (28 MPa. 1.28 GPa and 2.35%) for (PMMA: 0.3% WSP) composite specimens. And the highest value of hardness shore D was (77) for (PMMA: 0.3% WSP) composite specimen.
Highlights
This research focuses on the development materials used for manufacturing prosthetic which used the new materials that are eco-friendly and low - cost. Used the natural particles and synthetic particles to manufacturing prosthetic. A comparison of mechanical properties between environmentally friendly materials and industrial materials.
