High-strength 2D/2.5D carbon-fiber-reinforced carbon (C/C, CFC) composite structural plates, charging grids, hot-press sleeves, and M6–M24 threaded fasteners for vacuum furnaces up to 2,500 °C.
While monolithic graphite is brittle under tensile or impact loading, Carbon-Carbon (C/C or CFC) composite reinforces a pyrolytic/pitch carbon matrix with woven PAN carbon fiber plies—achieving 3–5× higher flexural and tensile strength (150–300 MPa) at half the thickness and weight of steel or molybdenum.
Unlike metals that soften above 1,200 °C, C/C composite actually increases in strength up to 2,200 °C, making it the premier material for thin vacuum-furnace charging trays, hot-zone protective liners, SPS/hot-press outer hoop sleeves, and high-torque M6–M24 bolts and nuts.
