Abstract

[en] The advanced properties of carbon fiber reinforced composite materials, such as their low
strength and stiffness-weight ratios, make them a very attractive alternative for aerospace
applications, particularly for fan-blade design. However, their integration is truncated due
to its susceptibility to impact phenomena, and the lack of reliable numerical models that
capable to predict their damage response. Aircraft components, particularly fan blades,
are known to experience harmful foreign impact events e.g. tool-drop, ice ingestion, bird
strike, etc. The aim of this project is to provide the necessary theoretical background on
the failure mechanisms experienced by a composite during an impact, and to build Foreign
Object Impact (FOI) model on a rectangular composite plate for the cases of low and high
velocity. The focus of the high velocity model is to validate the ballistic response of a
composite rectangular plate by means of experimental and numerical results found in the
literature [1, 4], and to analyze the main sources of damage present and the influence of
relevant physical properties i.e. thickness, stackup sequence, etc. On the other hand, the
low velocity model is focused in delamination modelling. Two different sub-models are
developed in this case: (1) ”Elastic Model”, in which only interlaminar damage between
the plies is modelled and, (2) ”Failure Model”, where both intra and interlaminar failure
are considered. The final goal is to provide an organized numerical methodology to model
an impact on a composite structure and to analyze the effect of the projectile velocity on
the damage mechanism developed by the composite target.
