Located within multiple interconnected labs on the PNNL-Richland campus, the Polymer and Composite Materials Laboratory comprises staff who collaborate with various organizations on advanced materials research. Offering support to academia, industry partners, Department of Energy (DOE) national laboratories, and others, the Laboratory's research focuses on the fabrication, testing, and characterization of polymers and reinforced composites to enhance durability, performance, and environmental compatibility.
Researchers specialize in innovative recycling and upcycling of carbon fiber composites, environmental degradation analysis, and hydrogen durability testing. Capabilities include low-cost and high-throughput composite manufacturing, rubber compounding, and adhesive bonding of multi-material systems. Through experimental and computational modeling, experts also investigate energy absorption, impact resistance, and damage behavior to develop next-generation materials, including hybrid composites with bio-based and geo-based fibers.
