Multifunctional 3D Printable Polymer-Metal Composites

Ongoing
Recent advances in additive manufacturing (AM) have positioned metals and polymers as two key materials. Typically, AM of these two materials involves incompatible methods and conditions. The novel multifunctional polymer-metal composites in this project incorporate low-melting alloys with

Precursor Material Qualification

Completed
To develop, utilize, and analyze methods of characterizing the precursor materials in additive manufacturing in both virgin and recycled states with the goal of advancing measurement science to benefit the AM community. The components of principal interest will include the rheological, size

Metrologies for Non-linear Materials in Impact Mitigation

Ongoing
Overview This project develops fundamental structure-property measurements on model materials and novel material chemistries from quasi-static to dynamic rates. The goal is to foster a materials by design approach for novel energy dissipation and force re-direction mechanisms. Processing-Structure
