Our CVI furnaces are crafted to handle the rigors of aerospace, automotive, energy, defense, and advanced research applications, ensuring your processes achieve optimal outcomes every time.

What is Chemical Vapor Infiltration (CVI)?

Chemical Vapor Infiltration (CVI) is a sophisticated process used to densify porous preforms by depositing matrix material from gaseous precursors. This technique is essential for creating advanced composites with superior mechanical strength, thermal stability, and resistance to harsh environments.

In the CVI process:

• Porous fiber preforms (such as carbon or ceramic fibers) are placed in the furnace chamber.
• Precursor gases (e.g., methane, propylene, or other hydrocarbons) are introduced at controlled temperatures and pressures.
• The gases decompose and infiltrate the preform, depositing solid material (like pyrolytic carbon or silicon carbide) deep within the pores.
• Multiple cycles ensure complete densification, resulting in composites with near-theoretical density and outstanding properties.

Unlike traditional methods, CVI produces materials with minimal defects, excellent interlayer bonding, and enhanced performance in extreme conditions—making it ideal for critical components.
