The fully tested and approved nose landing gear doors of a
Dornier 728 have been redesigned using Evonik's new Rohacell®
HERO polymethacrylimide (PMI) closed-cell rigid structural foam
core material for a cost and weight comparison.

A

foam core/infusion design was
compared with a typical honeycomb/prepreg design. The
foam/infusion design resulted in an
out-of-autoclave (OoA) finished part
with 25% lower overall manufacturing
costs and a 19% weight saving for the
landing gear door, produced in almost
half the time. These significant weight
and cost savings achieved with a foam
core are likely to influence future
composite component designs and
prompt the reengineering of some existing aircraft components, especially
parts with more complex, curved and
angled geometric shapes.

effective serial production technologies for the fabrication and assembly
of lightweight carbon fibre reinforced
plastic (CFRP) components for
aircraft construction. Back in 2013,
CTC had a number of projects running to evaluate higher productivity
and lower cost methods of fabricating
lightweight CFRP sandwich parts for
class A and B aircraft applications.
Evonik submitted samples of its new,
damage-tolerant Rohacell® HERO
foam core to the CTC project team to
evaluate the high-performance core as
an alternative material to honeycomb.
A key time and cost advantage of
using a foam core is that it can be processed in one shot without the need
for autoclaving. According to Evonik,
from the current Rohacell® foam core
PMI material grades available, the
latest HERO range has significantly

Independent redesign project
This cost and weight evaluation redesign project was carried out independently by the Composite Technology
Centre GmbH (CTC), located in
Stade, west of Hamburg in northern
Germany. CTC, a wholly-owned
subsidiary of Airbus, specialises in
composite processing technologies. Its
primary objective is to develop cost-
