The 20th century noted the arrival of carbon fibre-reinforced polymer (CFRP) composites, however, since then they have found applications in many engineering domains. Their high strength-to-weight ratio made them ideal for aerospace applications. However, today, they are crucial in distinct industries, ranging from sports equipment to the automotive industry. Even though they are widely utilized, traditional methods of joining like bolting, riveting, and mechanical fastening pose grave challenges for CFRP. Knowing that the composite is anisotropic, these techniques are prone to delamination, generate stress concentrations, and damage the structure of the material. Whereas, the thermoset matrices of CFRP degrade at high temperatures, rendering welding inappropriate.
