Interfaces between two dissimilar materials play a key role in many areas such as aerospace, aeronautic and automotive sectors. This is particularly the case for fibre-reinforced polymer composites whose performances are mainly driven by the interface and interphase integrity. In this area, the challenge is to develop functional interfaces to contribute to developing the new generation of composites materials.
