Investigating the Effect of TiO2, CaCO3, and Al2O3 on Mechanical Properties of LDPE Polymer Composites Fabricated by Injection Moulding Technique | Chapter 9 | Technological Innovation in Engineering Research Vol. 4

In this study, CaCO3, Al2O3, and TiO2 reinforced LDPE composites that were inexpensively and efficiently functionally moulded into the shape of an ASTM-compliant die using an injection moulding machine are analysed. A variety of mechanical characteristics are evaluated on the produced specimens. This paper describes the characterisation and manufacture of Polymer Matrix composites that can be utilised as artificial bone implant materials. Bone damage can be repaired or replaced with artificial bone materials. Over the past three decades, a wide variety of implant materials, including metal alloys, ceramics, polymers, and other materials, have been created. The main concerns with metallic bone implants are stress shielding and bone regrowth. These challenges could be solved by polymeric bone implants. Polymer composites are a viable option practically everywhere because of their low cost, increased strength, and simplicity of manufacture. However, they have very little wear resistance and hardness when employed in their native state. In the current study, TiO2, Al2O3, and CaCO3 are employed as reinforcements while LDPE (Low Density Polyethylene) serves as the polymer matrix, providing information on the mechanical characteristics of polymer matrix composites. The samples were created using an injection moulding machine in accordance with ASTM standards, using varied amounts of reinforcement in the polymer matrix. Tensile and flexural impact tests are conducted.
