TLDR
In this article, the authors present methods for manufacturing a functionally graded polymer material, which consists of preparing a melted polymer mixture comprising a thermoplastic polymer and a magnetic filler dispersed in the thermoplastics, molding the melted mixture and applying a magnetic field to a portion of the mixture to form a functional grade polymer material.Abstract:
Disclosed herein are methods for manufacturing a functionally graded polymer material. The methods comprise preparing a melted polymer mixture comprising a thermoplastic polymer and a magnetic filler dispersed in the thermoplastic polymer, molding the melted polymer mixture and applying a magnetic field to a portion of the melted polymer mixture to form a functionally graded polymer material. The resulting functionally graded polymer material has a magnetic filler gradient formed through a thickness of the material.read more
