Cutting edge material science company that is developing the next generation of high strength composites MoreLess
Boston Materials is a U.S.-based advanced materials company that develops and manufactures next-generation energy-transfer composites for high-performance electronics, aerospace, and electrified mobility sectors. Its flagship product, Liquid Metal ZRT®, combines vertically oriented carbon fiber (via proprietary Z-axis Fiber™ technology) with a liquid metal matrix to deliver a step change in thermal interface performance. In testing on kilowatt-scale devices such as data center GPUs, the material has demonstrated a device-level cooling improvement of 5-8 °C relative to conventional thermal greases, with a preform design intended for seamless “drop-in” integration into automated assembly workflows.
Beyond thermal interfaces, Boston Materials applies its Z-axis fiber approach to composite reinforcements. Its ZRT interlaminar reinforcement films serve to mitigate delamination in layered composite structures by bridging inter-ply interfaces and enhancing out-of-plane mechanical integrity. The company also pursues applications in hydrogen fuel cell technology, working on lightweight bipolar plates made from recycled carbon fiber composites to reduce weight and cost in fuel cell stacks.
Boston Materials maintains a manufacturing facility in Billerica, Massachusetts, where it deploys roll-to-roll processing lines capable of scaling production to meet industrial demand. Its materials are built with reclaimed carbon fiber, aligning with sustainability objectives. The company has attracted venture funding to accelerate expansion in semiconductor, aerospace, and electrified-vehicle markets, positioning itself as a bridge between materials science innovation and deployment in energy-intensive systems.
