High Density Custom Carbon-Carbon Composite Preform for High Temperature Application
This carbon-carbon composite preform is a porous reinforcement skeleton made of continuous carbon fiber woven or laminated, designed for subsequent C/C composite densification processing, with excellent ultra-high temperature structural performance.
Our carbon-carbon composite preform is a dedicated porous carbon fiber reinforcement skeleton for manufacturing high-performance C/C composite materials, produced from high-strength PAN-based carbon fiber through professional weaving, laying, needling or 3D braiding processes, followed by high-temperature carbonization treatment to remove all organic sizing and impurities.
This preform retains the complete continuous carbon fiber network structure, no short fiber breakage or strength loss, and the internal pore structure is uniformly distributed. The porosity can be precisely adjusted between 30% and 55% according to customer process requirements, which can perfectly match the subsequent chemical vapor infiltration (CVI), pitch impregnation carbonization or resin impregnation densification processes.
The finished preform has excellent high temperature resistance, it will not decompose or soften even in an inert environment above 2000°C, and maintains extremely high structural strength and dimensional stability. Different from ordinary chopped fiber preforms, our 2D/2.5D/3D/4D structural design effectively solves the problem of easy delamination of traditional two-dimensional preforms, and significantly improves the interlayer shear strength and impact resistance of the final C/C composite parts.
This product is widely used in aerospace engine throat liners, high-temperature furnace heat insulation components, brake discs for high-speed aircraft and automobiles, nuclear industry high-temperature structural parts and other extreme working condition scenarios. We can customize the fiber orientation, density, pore size and overall dimension of the preform completely according to your specific part drawing and subsequent densification process parameters.
Every batch of preforms will be strictly tested for carbon content, porosity, compressive strength and dimensional tolerance before delivery, to ensure that it fully matches your subsequent C/C composite production process and stably produces high-performance finished parts.
