Senior Scientist · University of Delaware · company speakers →

Dr. John Tierney is a Senior Scientist at the Center for Composite Materials in the University of Delaware. Dr Tierney holds a Ph.D. in Materials Science and Engineering from the University and has an honors bachelor’s degree in mechanical engineering from the National University of Ireland. Dr. Tierney has extensive experience in design and processing composites and has been conducting research in innovative processing methods for manufacturing composites parts, which include automated fiber placement, discontinuous fiber processing (TuFF), pultrusion, induction lamination, VARTM processing, prepreg production, autoclave manufacturing, OOA processing, filament winding, and high-speed thermoforming. His work has focused on modeling material behavior as well as process optimization for manufacturing composites using numerous analytical and FE based methods. Dr. Tierney is lead inventor of TuFF (Tailored Universal Feedstock for Forming), a process that aligns discontinuous fibers to produce aerospace grade parts. Dr. Tierney was lead design for NASA’s next generation xEMU spacesuit HUT design. Dr. Tierney was task lead at enhancing soldier Protection to defeat evolving threats. This includes establishing processing-microstructure- performance relationships for the design, optimization, and manufacturing of UHMWPE composites. Dr Tierney was also task lead on composite manufacturing technologies for aerospace performance at automotive production rates using high speed thermoforming with NASA. Dr. Tierney is lead software engineer at UD-CCM and developed a generic set of design tools called CDS (Composite Design and Simulation Software) and the SMARTree infrastructure that represents the core of all analytical software tools for composites processing, mechanics, and design at CCM. These applications are currently distributed to sponsoring DoD agencies as well as industry and academic institutions worldwide.
