Adhesives are used to join most composites and plastic materials. They are known for improving stress distribution and expanding the choices of composites and dissimilar substrates throughout the vehicle. Adhesive is the most versatile bonding agent available today and is used by vehicle manufacturers to make cars lighter and tougher. Moreover, adhesives are made from precise blends of synthetic rubber elastomers, resins, and additives, such as photo initiators and stabilizers, which enhance the characteristics of tire reinforcement material. In addition, currently automobile manufacturers glue aluminum and composites together so that vehicle body parts are intact even at top speed and high pressure. Adhesives do not lose strength and hence are used for these applications. Furthermore, their bonding renders the vehicles noise free, durable, and safe by replacing conventional joining techniques, such as welding, riveting, and bolting.
