AvCarb® Carbon Fabrics
AvCarb® has been producing high quality poly1978. Drawing on unique carbon fabric processing
technology, AvCarb® carbon fabrics are designed tomeet the demanding requirements of gas
transport, motion control, electrical and elevatedtemperature applications.

performance carbon fabrics is the conversion of
PAN to a highly thermoset ladder polymer calledbuilding block for AvCarb® carbon fabrics, is then
are woven into a construction designed for theapplication.
To meet the demanding needs of the many

carbonized in Ballard’s proprietary AccuCarb™
continuous carbonization process. At this stage,
the fabrics have an 88-95% carbon content andare called “HC” grade fabrics. Vacuum batch baking
at extremely high temperature results in our“HCB” grade fabric, a 99+% carbon fabric withgraphitic properties.
Produced in long, continuous rolls, AvCarb® carbon
fabrics are easy to store, handle and use. Their
uniform properties over the length and width ofeach roll, and from roll to roll, not only assure
product consistency but also lend themselves toeasy integation with continuous manufacturing
processes.
All AvCarb® carbon fabrics are manufactued using
processes and quality systems registered by
Det Norske Veritas, a major international certifying
body, to be in conformance with ISO 9001 andISO/TS-16949. As a Tier 1 supplier of critical drive
train components to the automotive industry,
AvCarb® has the ability to provide quality products,
on time, with added value.
