Carbon-Carbon Composites

One of the most advanced and promising engineering material is the carbon fiber reinforced carbon matrix composite (C/C composites). Carbon-Carbon composites are among the strongest and lightest high-temperature engineered material in the world. Compared to other materials such as graphite, ceramics, metal, and plastic, it is lightweight and strong and can withstand temperatures over 2000℃ without any loss in performance.

CFC DESIGN TECHNOLOGY

CAPABILITIES & SOLUTIONS

Since its establishment, CFC Design has been promoting the new technologies of advanced composite materials – including the C/C composite – by introducing innovative manufacturing methods to diverse segments such as the high temperature, friction material, and advanced technology industries. We offer our expertise in the areas of innovation and co-development through a wide range of high-performance composite materials and engineering design to help improve productivity and contribute to energy savings.

PY MANUFACTURING

Although the C/C composite has excellent performance, the conventional manufacturing method (impregnation method and CVD method) requires complicated steps and requires very long time to manufacture. And as a result it was extremely expensive. CFC have succeeded in a process simplification, shortening delivery time and reducing costs by developing innovative new manufacturing method called preformed yarn method (PY method).

PY MANUFACTURING

FIBER ARRANGEMENTS

Since the C/C composite is a composite material reinforced with carbon fiber, by controlling the orientation (fiber direction) and length of the fiber, which is the source of its mechanical strength, it is possible to derive various characteristics according to the specific application. Through the accumulation of technology over the years, as shown in the table below, we can realize many product types and can respond to customers’ diverse needs.

Unidirectional Fiber Orientation Long-fiber Long-fiber Application: High-strength Rods, etc. Features: Long Rods width maximum bending Strength: Used for Springs & Pins
Bi-directional Fiber (0°/90°) Orientation Long-fiber Long-fiber Application: Plates, Large-size boards Features: Heat-treatment trays, etc. Most common use in the heat-resistance field
Multi-directional Fiber Orientation Short-fiber Short-fiber Application: Bolts & Nuts, Precision Jigs, etc. Features: Well suited for precision machined parts and complex components

C/C MC [Carbon-Carbon Metal Composite]

One of the unique characteristics of C/C Composite is its porous structure within the carbon matrix. By introducing metal into the carbon matrix, we are able to transform the characteristics of the C/C Composites. With the addition of metal to the main structure of C/C composite, the new material brings out effectively the best functions of each element so that it can be used for different kinds of application. We have defined this as C/CMC, Carbon-Carbon Metal Composite, which is superior in wear resistance, corrosion resistance and sliding property.

C/C MC

PRODUCTS

The biggest feature of C/C composite is its excellent heat resistance. Since it is heat-treated at temperatures ranging between 2000℃ to 2500℃ during the manufacturing process, there is no deformation due to heat. And with its low susceptibility to thermal shock, it can withstand repeated heat treatment. The 1.6 g/cm3 in density makes its total weight approximately 1/5 of steel, making them significantly lightweight. Furthermore, since it is a graphite material reinforced with carbon fiber, the strength is 3 to 5 times that of the conventional graphite material, and it will not be damaged even if it is dropped.
