The Center for Novel High Voltage/Temperature  (HV/T) Materials and Structures  evaluates, designs, models, and develops novel high voltage and high temperature materials and structures for energy transfer, aerospace, automotive and other applications.

Center Mission and Rationale

The mission of the Center is to design, create, and study new advanced materials as well as evaluate existing materials and structures for a range of engineering applications. We use state-of-the-art experimental and computational tools to conduct the multiscale characterization and modeling of such materials to obtain reliable predictive models. The Center has an interdisciplinary and diverse environment for faculty and students to work jointly with companies and organizations on novel materials and structures. The Center can provide research support to electric utility, aerospace, nuclear, military, environmental, automotive, health and other industries interested in the application of novel HV/T materials in their design practices. Various novel high voltage/temperature materials and structures for high energy transmission and other related applications with superior resistance to in-service conditions are being studied. Our ultimate goal is to provide outstanding research service to industries utilizing novel materials and structures subjected to extreme HV/T loading conditions.

Research program

Multiscale Design and Development of Novel HVT Materials

There is a need for new HVT materials with improved properties for a range of technological applications. The goals are: (i) To design and develop new conductive materials for electromagnetic shielding and other applications; (ii) To design and develop new alloys for improved conductivity, strength, and corrosion resistance; (iii) To develop new silicone rubber RTV materials with improved resistance to in-service aging.

Advanced Manufacturing of HVT Materials

New manufacturing techniques can reduce cost, accelerate production, allow complicated designs, and offer tailored properties. This project will explore the effect of powder oxidation on mechanical properties of titanium parts made by Additive Manufacturing (AM). It will also research manufacturing of metal and polymer materials and the design of novel AM foams including tailoring microstructures during the AM process. Lastly, it will look at manufacturing of materials for aging prevention of fiber reinforced polymer matrix composites (PMC).

Prevention of Environmental Degradation of HVT Materials and Structures

Materials subjected to long-term exposure to harsh environments can experience significant degradation in properties. The goal of this project is to explore ways to help mitigate the effects of aging on material durability. This can be done by modifying the material constituents, or by using coatings. Specifically, this project focused on the aging of polymer nanocomposites, corrosion resistance of coatings, and the corrosion resistance of basalt fiber composites. 

Impact Damage Prevention of HVT Materials and Structures

There are several goals and objectives of this base project. In particular, we investigate effects of mechanical impacts on HV transmission infrastructure. We also design inspection, monitoring, and reliability assessment methods for impact damage and develop feasible protections against impact damage from a variety of sources ranging from negligence to terrorism. We will also develop a novel impact resistant structure - material system that can resist high velocity impacts.

Health Monitoring of HVT Structures

The needs are: (i) Standard and novel HTLS conductors, HV insulators, transformers, airframe structures … can fail (sometimes catastrophically) in service. (ii) Novel health monitoring techniques need to be developed. (iii) New models of failure are also needed for better monitoring. The goals are: (i) To develop novel health monitoring techniques for HVT applications; (ii) To develop comprehensive electro-thermo-mechanical full-scale models of conductors/cables and related HV/T structures to understand mechanical responses of cables and other systems due to heterogeneous material structures (e.g. nanocomposites…).
