All the benefits of Ribtec's proven Rapid Solidification process in semi-continuous metal fiber form
Micronic effective diameters and semi-continuous as well as shortlength fiber filament lengths, combined with Ribtec's range of alloys and superior mechanical properties, have unique applications for the Automotive Industry.
Superior Resistance to High Temperature Corrosion
Ribtec RS stainless steel fibers are spun directly from the melt using the
company's advanced Melt Overflow (MO) processes. Rapid cooling of the fiber during
manufacture (equivalent to 100,000°C per second) "freezes" the metallurgical
structure, capturing it in an optimum state to resist high temperature corrosion - a state
which is impossible for conventionally cast steel to match.
The RS processing maximizes the effective distribution of the primary nickel and/or chromium alloying elements throughout the fiber while simultaneously minimizing grain size. When coupled with Ribtec's skill of blending non-standard levels of performance-enhancing key trace elements to the melt, a unique range of dedicated alloys have been produced which provide outstanding oxidation resistance and unmatched performance at elevated temperature.
As Ribtec produces its own high quality steels, we have developed a range of alloys to cope with the full diversity of service temperatures, operating conditions, combustion gases, etc. When coupled with the benefits of RS processing, Ribtec's alloys provide outstanding high temperature durability and substantially outperform other so called "equivalent" fiber types on the market with similar Cr and Ni additions.
Fiber Size
Effective diameter cross-sections from 60 to 120 microns; fiber length from .25 inch long to semi-continuous. For special applications, other lengths and diameters are also available.
Custom Forming and Packaging
Whether the application calls for bundled, semi-continuous metal fibers in a spirally wound continuous mat, shortlength fibers in 2 lb.plastic bags, or anywhere in-between, Ribtec can accommodate the customer's specification. The rough cast surface texture and irregular profile of Ribtec RS guarantees "mechanical interlock" with neighbor filaments in continuous mat form, yet with Ribtec's experience in the field, we can size the aspect ratio of discreet shortlength fibers so that balling when mixing is minimized. And, when used in composite media, the unique "kidney shaped cross-section" provides a higher specific surface area for bonding with substrates than round or flat fibers.
