Thaero LLC, a US-based leader in high deposition rate hybrid manufacturing, specializes in aerospace-grade metal-matrix nanocomposites. Our mission is to strengthen the nation's defense industrial base through the commercialization of advanced materials. Collaborating with top US universities, National Laboratories, government agencies, and leading equipment manufacturers, we aim to advance frontier technologies. Utilizing scalable additive manufacturing techniques, we develop high-temperature nanomaterial-infused alloys essential for defense, space, and nuclear sectors. Our extensive IP portfolio includes eight exclusively licensed patents from FIU, covering hybrid friction stir additive manufacturing, cold spray additive manufacturing, wire arc additive manufacturing/direct energy deposition, ultrasonic casting, and thermal spray. Our applications include lightweight structural alloys, terrestrial and hypersonic vehicles, lunar and Martian landers, lightweight ballistic materials, high-temperature alloy structures, high thermal conduction aviation components, and radiation-hardened alloys. We innovate by integrating Boron Nitride Nanotubes (BNNTs) into lightweight alloys, creating a multifunctional super metal matrix nanocomposite. This material offers exceptional properties such as radiation shielding, increased mechanical strength, enhanced ductility, improved wear resistance, superior thermal conductivity, and electrical insulation, maintaining thermal stability above 900 degrees Celsius in air. Thaero aims to revolutionize aerospace manufacturing through technological advancements and strategic partnerships, enhancing national defense and driving innovation across industries.
