Rapid Chemical Vapour Infiltration (r-CVI) the world’s fastest process for the manufacture of CFC components

CVT have invented the world’s fastest Chemical Vapour Infiltration (CVI) process. This patented r-CVI process makes it possible to compact carbon fibre preforms in only a few days. The strength of this process is its speed, and thus cost-efficiency. The process is ideal not only for prototype development and sample production of C/C products, but also for mass production.

We are able to optimise the morphology of the carbon to the matrix and so adapt the material for customers’ specific applications. Our recognised technology is already used by leading companies in the high performance industry today.


Denser, tougher, more efficient: the properties of CVT’s carbon components

The quality assurance processes, years of experience and the commitment to developing improved solutions, tailored individually to our customers’ needs guarantee high-quality products which meet the extreme requirements of our customers.

Rapid (r-CVI)

Our patented r-CVI process makes it possible to obtain the desired products within a very short time. It is currently the fastest method worldwide of manufacturing products using the Chemical Vapour Infiltration. This makes it possible for us to offer our customers correspondingly attractive prices, both for prototypes and in mass production

Extremely uniform densification

High performance products require consistent compaction in order to deliver the necessary quality at any time. Our process allows us to ensure particularly consistent infiltration and compaction.

Machinable

Our CVI products can be further processed by machine, making possible special forms, surfaces or applications.

High density

The aim of the CVI process is to achieve a high density and thus maximum stability. Due to our experience and expertise we are able to achieve maximum values in terms of density.

Matrix can be altered during the process

Adjustable parameters such as temperature, gas concentration and pressure allow us to adjust and optimise the texture of the infiltrated matrix carbon, in terms of its morphology and structure or density, during the CVI process.

Porous surface

Depending on the planned application, there are different requirements regarding the surface of the product - the aim is to achieve either a smooth or a porous surface. Since with the r-CVI process the compaction of the porous material takes place from the inside outwards, it is possible to create an open porosity on the surface. This helps with the mechanical keying of coatings or surfaces to allow bonding to the surface.

Adjustable carbon morphology

The compaction of the carbon felt with different carbon morphologies allows the friction coefficient of the matrix carbon to be specifically adjusted.
