Carbon Fiber Composites


Carbon Fiber Composite Fixture from CeraMaterials

What is Carbon Fiber Composite?

Let’s first start with the nomenclature. Carbon Fiber Composite is also referred to as Carbon-Carbon Composite, CFC, or Carbon Reinforced Matrix Composite. All of these aliases refer to this product.

Originally developed for use in the aerospace sector, CFC has become an extremely cost-effective solution for furnace fixture applications. The unique attributes of CFC offer advantages compared to metal and graphite fixtures. The material can be provided in a wide variety of sizes and geometric shapes.

Custom Fabrications

Fabricated shapes include but are not limited to: Sheets, Angles, U-Channels, Rings, Tubes, Pipes, Cylinders, Bolts, Washers, Heating Elements, Shelving, Survey Racks and Baskets for heat-treating.

Benefits

  • High strength and modulus.
  • Fire resistant and dimensionally stable.
  • Configuration of Carbon Fabric.
  • Fatigue and fracture resistant. Cracks will not propagate as with molded graphite fixtures.
  • Lightweight and low thermal mass permitting one to load more parts in each furnace due to the material’s excellent strength to weight ratio while reducing cycle time.
  • Thermal deformation resistant. CFC will remain flat and increase in strength at elevated temperatures reducing scrap and maintaining stricter part tolerances in comparison to metal which warps over time.
