River generate practically inexhaustible quantities of
regenerative power. At the brand-new carbon-fi bre
plant operated by SGL Automotive
Carbon Fibers,
ajoint venture between the BMW Group
and the SGL
Group, textile fi bres are refi ned into
carbon-fi bres.
50,000 of these individual fi laments are condensed
into fi bre bundles at the Moses Lake facility,
wound
onto coils and shipped to Wackersdorf in Bavaria.
It is in Wackersdorf that the BMW Group and its
joint-venture partner, the SGL Group, have built
aone-of-a-kind textile plant to supply the body con-
struction process. Here the fi bre bundles are woven
together into textile sheets (so-called fabrics) and
wound into rolls. Once di erent fabrics with di erent
fi bre alignments are combined, highly integrated
large-surface body panels with completely di erent
strengths and thicknesses can be customised. This al-
ready represents one of the outstanding features
of CFRP – the properties of aluminium or steel
components, in contrast, can only be customised
with great di culty. The body of the Megacity Vehicle
will therefore use much fewer components than a
steel body. This not only simplifi es the production
process, but also reduces vehicle mass. Lower weight
also extends electric vehicles’ potential range – which
makes the use of CFRP an important factor in jump-
starting e-mobility.
However, there are several reasons why this high-
tech material has so far been used almost exclusively
in small-series production and prototype construction.
CFRP components for motor racing and aerospace
have mostly been produced by hand in a
time-con-
suming and cost-intensive procedure. After soaking
We are building the car bodies of
tomorrow right here on highly e cient
knitting machines.
