Carbon Fiber Sheets & Composite Laminates for Industry

As an expert in all things carbon, American Carbon Company regularly meets the needs of specialty customers with application specific carbon fibers and carbon fiber composites.  Sometimes called carbon-carbon composites, these materials combine the rigidity and strength of carbon fiber with the advanced thermal properties of graphite.  While other materials can be substituted for the graphite (such as silicon carbide or boron), we prefer to focus on graphite composites as that is our primary focus.

Applications

Carbon fiber sheets and composite laminates from American Carbon are used wherever high strength, low weight, and dimensional stability are critical. Stock carbon fiber sheets provide reliable stiffness and excellent fatigue resistance, making them suitable for structural panels, lightweight brackets, enclosures, and precision components in aerospace, automotive, marine, and industrial equipment. Their corrosion resistance and predictable mechanical behavior allow designers to replace aluminum or steel without sacrificing performance.

​

Carbon carbon composite laminates extend these advantages into extreme thermal environments. These materials combine carbon fiber reinforcement with a graphite matrix, resulting in stable performance at elevated temperatures and resistance to thermal shock. They are used for tooling fixtures, furnace components, high temperature wear parts, friction surfaces, and energy applications that cannot tolerate thermal expansion or material degradation. These laminates maintain structural stability in conditions where metals and polymer based composites lose rigidity or oxidize.

​

Both material types are engineered for machining and fabrication. Carbon fiber sheets can be trimmed, drilled, bonded, or fastened into assemblies with minimal weight added, while carbon carbon composites can be finished to tight tolerances for precision tooling or production components. Whether the application calls for a lightweight structural panel, a rigid composite bracket, a heat resistant tooling plate, or a custom part that maintains strength under load, BADGERADVANCED Carbon Fiber provides reliable material options ready for manufacturing and end use.

Manufacturing Process

Carbon fiber sheets supplied by American Carbon begin with layers of woven or unidirectional carbon fiber fabric that are impregnated with a controlled amount of resin to ensure uniform wet out and fiber alignment. These plies are stacked in specific orientations to achieve the required stiffness, strength, and dimensional characteristics for the final part. The layup is then consolidated under heat and pressure to eliminate voids and create a stable laminate. Once cured, the panels are trimmed, surface finished, and inspected for fiber alignment, thickness uniformity, and surface quality.

​

Carbon carbon composites follow a more specialized process that replaces the resin system with a carbon rich matrix. The initial layup mirrors conventional carbon fiber, but the laminate is then heat treated in an oxygen controlled environment to convert the resin into carbon. This pyrolysis stage creates a porous carbon matrix that is repeatedly densified using additional carbon rich impregnation and high temperature processing. Each cycle increases density, reduces porosity, and improves mechanical strength and thermal stability. The end result is a carbon fiber reinforced carbon matrix that performs reliably in extreme temperature environments where metal or polymer based composites lose structural integrity.

​

Both material families rely on controlled fiber orientation, accurate temperature and pressure profiles, and careful quality checks at each step. Carbon fiber laminates are built to offer predictable stiffness with minimal weight, while carbon carbon composites are engineered for thermal stability, wear resistance, and long service life under elevated temperatures. American Carbon sources material from manufacturers who follow strict processing controls, which ensures consistent quality for machining, bonding, fastening, and final part fabrication.
