Carbon Fiber-Reinforced Carbon Fixtures

Semicorex Carbon Fiber-Reinforced Carbon Fixtures is a light-weight, high-strength composite material capable of withstanding temperatures over 3000°C in many environments.

It is made of Pan-based carbon fiber through a special process like composition, curing, sedimentation, purification treatment.

Applications include: Protective liners and melt covers; Solar technology; Vacuum metallurgy; Non-oxide ceramic production; Chemical industry new material.

Carbon Fiber-Reinforced Carbon Fixtures offer high-performance structural components that are ideal for high-temperature thermal processes. These fixtures utilize advanced carbon fiber composites to create the best possible combination of high-strength carbon fiber and high-density carbon matrix material for maximum mechanical strength, thermal stability, and long service life. Fixtures made of carbon-reinforced carbon are typically used in high-temperature heat treatment, semiconductor production (die, package, etc.), crystal growing, and advanced material processing where high dimensional accuracy and high thermal reliability is required.

This fixture has been engineered for high temperature operations to provide a uniform support pattern, optimal gas flow, and optimal heat distribution with its precision grid lattice structure. These fixtures would be ideally suited for wafer processing, sintering, heat treatment, and crystal growing due to their unique carbon fibre-reinforced carbon cellular structure that provides a mechanically stable and highly consistent heat source.

Advanced Carbon Composite Construction

Carbon Fiber-Reinforced Carbon fixtures are manufactured by reinforcing a carbon matrix with high-strength carbon fibers through advanced composite processing techniques such as resin impregnation, carbonization, and high-temperature graphitization. This process creates a material with significantly improved mechanical strength compared with conventional graphite components.

The carbon fiber reinforcement greatly enhances the fixture’s ability to withstand mechanical loads and thermal stresses. Even under repeated heating and cooling cycles, the composite structure maintains its integrity without cracking or deformation. This makes C/C fixtures an ideal solution for demanding industrial processes that operate at temperatures exceeding 2000°C.

Optimized Grid Design for Thermal Efficiency

The three-dimensional grid system of this fixture has numerous practical advantages for use in the high-temperature processing systems. For example, the evenly spaced lattice allows free movement of heat throughout the entire structure, which helps create a consistent thermal environment within the furnace or reactor chamber.

Since this is an open grid design, there are benefits to gas flow and a reduction of thermal gradients that are common to processes such as chemical vapor deposition (CVD), sintering and annealing because of the more consistent distribution of heat through the fixturing system. So, by helping achieve consistent thermal conditions, the fixture promotes stable processing conditions and improved uniformity of the finished product.

In addition, the grid structure provides consistent mechanical support while reducing the overall weight of the component. As a result, this component’s lightweight structure has less thermal inertia, resulting in shorter heating and cooling cycles and increased efficiency of the furnace.

High Purity and Chemical Compatibility

Carbon Fiber-Reinforced Carbon fixtures are typically manufactured using high-purity carbon raw materials, making them suitable for applications that require strict contamination control. In vacuum or inert atmospheres, the material remains chemically stable and does not release impurities that could affect sensitive processing environments.

For more demanding applications, these fixtures can also be enhanced with protective coatings such as silicon carbide (SiC) to improve oxidation resistance and extend service life in reactive or oxidizing atmospheres.
