Investigation on Surface Modification of PLA Composites by Adding Graphene Using Heat Assisted Friction Stir Process

Abstract

Conventional materials have significant limits when it comes to their ability newlineto concurrently possess high strength and stiffness while maintaining low density. newlineApplications that require outstanding performance and low specific weight are driving newlinethe development of composites. The exceptional abilities of composite materials in part newlineintegration are evident, as numerous metallic components are effectively replaced by newlinecomposites. Polymers have the advantage of being able to alter their physical properties newlineto suit specific applications with a simple change in composition. This makes them an newlineexcellent material option for implants, as well as a viable alternative to metals and their newlinealloys. newlineIn recent years, there have been notable advancements in biomaterials and newlinetechnology. As a result, the body is increasingly using them to replace missing or newlinedamaged hard tissues, such as in dental and orthopaedic implants. Biomaterials, such newlineas polymers, ceramics, and metals, are commonly used in a variety of biomedical newlineapplications, such as joint replacement and bone regeneration, as well as for medical newlineimplants, due to their extensive benefits newline
