The automotive field has always been one of the driving fields for mechanical research and development for many years. This brought many new complex and expensive solutions to be investigated and developed mainly in racing or high-end applications and then commercialized on road or commercial vehicles later on. Composite materials are a great example of this and in particular in the last decades a lot of research went into adhesive bonding, a technique used to join similar or dissimilar materials of any kind. Adhesive bonding applied to composites allowed to reduce drastically the weight of assemblies usually made of many components, which traditionally were made out of metals and joined by welding or bolted connections which increased a lot the weight of the structures.
