In different industrial fields such as transport or aerospace, there
is currently a strong research effort on structural weight reduction. One of the most promising solutions, of course, is the use of
composite structures. However, due to an intensifying operational
dynamic environment and growing durability requirements, it
seems hard to find a design compromise. One way to manage this
is to design and manufacture smart composite structures, which
can adapt to their environment.

his article provides an overview of
the technical issues associated with
the production of smart composite
structures. The main manufacturing features are illustrated with the case study of
a smart automotive spoiler. Developed at
the IRTES-M3M laboratory over the past
12 years, the manufacturing process used
enables the design of a large set of smart
structural applications.

What is a smart
composite structure?
First of all, let us define what a smart
structure is. In 1996, Spillman, Sirkis and
Gardiner [1] established a definition based
on an extensive survey. A smart material/
structure is a physical material/structure
that combines a definite purpose, the
means and requirement to achieve this
purpose, and the pattern of functioning of a
universal computer or a biological entity.

Akhras [2] summarized the basic components of any smart system as follows (the
equivalents in the human body appear
between brackets):
- data acquisition (tactile sensing): collecting the required raw data for appropriate
control and monitoring of the structure;
- data transmission (sensing nerves): forwarding the raw data to local and central
control units;
- command and control centre (brain):
analysing the data, reaching the appropriate conclusion and determining specific
actions;
- data instructions (motion nerves): transmitting the decisions and the associated
instructions back to the members; and
- controlling devices (muscles): taking action by triggering the controlling devices/
units.
A smart composite structure is a host
structure made of a composite material
in which the different basic elements described above are embedded. Due to their
constitution (plies and resin) and manufacturing method, composite laminates
are particularly suitable for integrating
exogenous components into the heart of
the material. This type of integration can
hardly be considered for traditional materials, in particular metal materials. Figure 1
shows the standard architecture of a smart
composite structure.
