AvCarb Material Solutions is a Lowell, Massachusetts manufacturer of engineered carbon fiber materials - gas diffusion layers, felts, papers, woven fabrics and molded graphite laminates - built for the toughest electrochemical, thermal and friction jobs. With roots tracing to AVCO in the early 1960s (the same Lowell operation that helped develop Apollo's AVCOAT heat shield), AvCarb now supplies the carbon guts of hydrogen fuel cells, electrolyzers and redox flow batteries, alongside legacy work in automotive wet friction and even fishing-reel drag washers.
Chris Holmes is the President and CEO of AvCarb Material Solutions, a Lowell, Massachusetts maker of engineered carbon materials - the felts, fabrics, and papers that quietly sit at the heart of hydrogen fuel cells, electrolyzers, and flow batteries. An MIT-trained systems engineer with a hybrid technical-and-business background, he is a turnaround specialist who has led high-technology businesses from start-up scale to north of $200M in revenue, largely inside private-equity portfolios. At AvCarb he is steering a company with 1960s roots toward the center of the clean-energy transition.

Mike Zimmerman is the founder and CEO of Z-Polymers, the Lowell, Massachusetts company behind Tullomer, a melt-spun super polymer marketed as stronger than PEEK and stainless steel yet light enough to print on a desktop 3D machine. A career materials scientist with a PhD in mechanical engineering, he spent nearly 15 years at Bell Labs and Saint-Gobain before founding a string of deep-tech ventures including Quantum Leap Packaging and the solid-state battery company Ionic Materials. He has also taught materials science at Tufts University for more than three decades.
