Heroldstatt, Germany-based
injection molder 1A Autenrieth
Kunststofftechnik GmbH & Co.
KG is launching a thermoplastic
composite replacement for rebar
reinforcement technology at
Fakuma 2023.
Rebar is conventionally associated
with the steel and more
recently glass-reinforced plastic
bars used in reinforced concrete.
But Autenrieth's rebar for reinforcement
of thermoplastic moldings
consists of a wire-shaped
pultrudate with polypropylene,
reinforced with 30 percent continuous
glass or carbon fi bers.
The pultruded wires are bent
on equipment from Reutlingen,
Germany-based wire bending
machinery producer Wafi os AG,
The selective
nature
of the encapsulated
r
ein for cement
brings
load-oriented
stiffness and strength to the
parts of moldings where they
are most needed, which would
otherwise require moldings to
be much thicker and heavier for
the same strength and rigidity.
The Wafi os equipment can create
complex, star-shaped rebar
without shaping tools by alternately
bending the profi le to the
right by 72 degrees and to the
left by 144 degrees.
Rebar was developed in Germany
by 1A Autenrieth; Augsburg-based
Fraunhofer IGCV
institute for casting, composites
and processing technology;
Coburg-based automotive components
Brose Fahrzeugteile SE;
and automaker Porsche.
The German Federal Ministry of
Education and Research (BMBF)
funded the project as part of the
HYMAT materials platform for
hybrid materials. It received an
innovation award at the 2023 JEC
World composites fair in Paris.
The DRIFT production line
at IGCV involves a winding machine
from Oldenburg, Germany-based
Herzog GmbH that
feeds wound glass fi ber roving
directly into IGCV's pultrusion
line, followed by bending.
Two large-scale auto demonstrations
have been developed,
but Porsche does not yet want
to reveal any details, except that
they are aimed at applications in
the Porsche Taycan.
It enables high-volume,
cost-effective and resource-saving
production of complex lightweight
structures with high
design freedom. One of the two
demonstrators produced in the
project offers 50 percent weight
savings compared with deepdrawn
aluminum - 0.95 kilograms
instead of 1.83 kg.
1A Autenrieth foresees application
areas for rebar hybrid
technology in aerospace, mechanical
engineering, auto, utilities
and consumer products.
Steffen Autenrieth, managing
director since 2006, said: " Rebar
can be used wherever metals are
currently used, which would ultimately
be more cost-effective,
safer and conserve resources. "
Autenrieth explains that " 1A "
in the company's name was a
deliberate strategy in order to
be listed high up in B2B databanks
and the company register,
without having to pay for a privileged
position.
The company was founded in
1977 by Heinz Autenrieth. Its 18
injection molding machines at 1A
Autenrieth cover clamping forces
of 50-462 tonnes, capable of
molding shot weights from 0.1 to
1,500 grams. Its present machine
park list shows SHI Demag accounting
for 13 of the machines,
along with machines from Dr. Boy
and Battenfeld, but two unspecifi
ed machines have been recently
replaced by Arburg machines.
Fused deposition modeling 3D
printing machines acquired in
2020 produce parts in ABS, ASA,
nylon 12, polycarbonate, PC-ABS,
PEI and PEKK, in build volumes
up to 406 by 355 by 406 mm.
