Study of self-healing capability of composite material with phase changing paraffin wax and graphene

Abstract

The main aim of this research work was to conduct an experimental study of self-healing capability of the composite material by using phase changing material. The phase changing material utilized was “paraffin wax” for healing the material made up of the carbon fiber and epoxy. Three combinations of carbon fiber reinforced epoxy with phase changing materials were prepared i.e., plain carbon fiber epoxy without any phase changing material, carbon fiber epoxy with paraffin wax and carbon fiber epoxy with paraffin wax nano graphene. The fabrication of the carbon fiber composite material inside the capsulation has been done by keeping the 3d model. To identify the structural properties of the material some tests were done i.e., the tensile test and flexural test at normal room temperature and pressure. Damage was produced at the center of each specimen with the help of a Barcol hardness test machine. The Specimens were tested without indentation damage, immediately after indentation damage and after 48 hours of producing damage.
