Abstract

Additive manufacturing is one of the greatest advancements in manufacturing of the last century, however it has only been applied in a limited fashion to electroactive materials. One such material is the polymer, polyvinylidene-fluoride (PVDF). PVDF is capable of being additively manufactured into its piezoelectric form by extrusion through an electric field. Being able to predict the properties of additively manufactured PVDF by carefully tailoring the electric field-assisted extrusion process could lead to huge advancements in the sensing and actuation capabilities in aerospace, bio-medical, and other industries. This study shows the mechanical properties of the extruded fibers can be predicted by accounting for the size of the extruded fibers and the extrusion path used to create the fibers.

Biography

Andrew Hedlund is a graduating senior in Aerospace Engineering with a focus on mechanics and advanced materials. He was awarded the Opportunity for Undergraduate Research Experience Fellowship last year for his work on the precursor to the project described above. He is also a Distinguished Undergraduate Research Fellow in the Mechanical and Aerospace Engineering Department at MS&T. As such he has furthered his research on piezoelectric materials designing MEMS and integrated electromechanical systems for a corporate sponsor.
