Résumé:
The main objective of this work is to study the impact behavior composite
materials and their behavior more precisely the impact of the ball by the method of
planning experiments. The studied materials are laminated to build a matrix reinforced
with polyester and glass fibers. This thesis consists of five chapters. The memory map
is as follows:
The first chapter introduces the materials composites. Their classifications,
consideration of their use, their structures and their families.
In chapter 2, we presented the aramid fibers which are specialized in ballistic
protection, the chemical structure of aramid, mechanical properties, the manufacturing
process and especially their use.
In the chapter 3, a broad definition of impact, kinetic energy and the various
applications (aerospace, automobile and military). The Gillet armor is our object.
In the chapter 4, a well defined representation of the method used in our work,
the method of planning experiments.
The Chapter 5 presents the experimental work carried out to study the behavior
of composite materials to the impact of ball, a presentation of samples, their
manufacturing processes, the dimensions and materials used for this experiment. The
sequence of experiments.
In the last chapter, an analysis of the results was performed using a
mathematical model.
