lNSA Rouen Normandy:
Aeronautics composites undergo trial by fire
For a dozen years now, GPM and CORIA, two French National Centre for Scientific Research laboratories,
have combined their expertise and resources at the INSA campus in Rouen, Normandy, to develop experimental
and numerical analysis tools dedicated to studying the mechanical resistance of aeronautics
composites to kerosene flames.
A
t the crossroads of mechanical,
physico-chemical and
thermal issues, the test benches
developed within the framework
of the DECOLLE (Carnot Institute
Energy and Propulsion Systems) and
Aeroflamme (Normandy Region/
FEDER) research projects aim to
reproduce, on the laboratory - and
therefore small - scale, the effect
of heat flow and kerosene flames in
conditions that are close to critical
service conditions. This information
is fundamental for comprehending
and quantifying the multiphysical
phenomena at work on an industrial
scale (composite structures).
Industrial partnership
In keeping with a logical shift towards reducing CO2
emissions, efforts to reduce the
weight of aeronautical structures by using polymer matrix composite materials face increasingly
demanding safety standards. Over the course of the last few years, numerous
fires have broken out during flight, which has placed the " fire " issue at the heart of aeronautics
manufacturers' preoccupations. Understanding and predicting how composite
materials and, in fine, structures and assemblies will react to fire, is primordial. The
demand for numerical analysis tools and resources for suitable experimental characterisation
is therefore high. In particular, it is indispensable to be able to determine how
the behaviour and mechanical properties of composites exposed to kerosene flames
will evolve, depending on the conditions of the thermal stress (flow, temperature, duration).
Since 2019, we have collaborated with Daher Aerospace and SAFRAN Nacelles
on these issues.
«Understanding and predicting
how composite materials and, in
fine, structures and assemblies will
react to fire, is primordial.»
R&D approach
The GPM and CORIA labs link their
know-how and resources to provide
answers to manufacturers in the aeronautics
industry on issues involving
fire resistance (thermal response
and mechanical behaviour) of organic
matrix composites. Through their
work, four research professors, one
research engineer and three PhD students
are implementing characterisation
resources, developing a test platform
and numerical analysis tools.
These resources and tools contribute
to a common goal, which is measuring
the physical quantities that are
brought into play (temperature, loss
of mass, deformation, stress) in order
to study the thermo-physico-chemico-mechanical
coupling at work within
composite laminate materials.
From an experimental point of view,
the use of an industrial process type
burner (NexGen) allows the fire behaviour
of composite materials to be
100

characterised (ISO 2685). At this scale,
coupling with a mechanical load is not
possible. At the smaller scale of the
lab, our kerosene burner makes it possible
to conduct combined tests in controlled
thermal stress and mechanical
load conditions (FAA AC20-135). With
respect to a radiant cone, the thermal
stress induced by a flame is much closer
to a fire-type emergency situation in
an airplane. It is also possible to comprehend
the influence of a kerosene
flame on flow, wall temperature, and
time-to-ignition on the trailing side.
These tests nourish the exchanges between
industry, the EASA (European
Aviation Safety Agency) and the FAA
(Federal Aviation Administration) on
the evolution of fire certification standards.
The experimental data obtained
can be used by engineering and design
offices to determine the dimensions of
composite structures that will meet the
requirements of such standards.
