UNIDIRECTIONAL 12k CARBON FIBER CLOTH

Among all the composite materials, thermoset composites are the most used for structural applications. They are commonly designed in different configurations (with 12k uni- directional fiber or fabrics) and with different reinforcements, mainly glass fiber or carbon fiber, to achieve the mechanical properties required by the specific structural application. Their use in the automotive sector is rapidly increasing, especially for electric vehicles, and  they are widely used in the aerospace sector. Although these materials can reduce weight and emissions,there are many concerns about their full sustainability, because thermoset resins are not fully recyclable and are mainly petrol based. The manufacturing process of thermoset composites is therefore not fully sustainable and eco-friendly. For example, epoxy resin synthesis has a significant environmental impact, since it negatively contributes to the total carbon footprint and accordingly to the greenhouse emissions of the automotive industry. Moreover, regulations in terms of pollution and environment have been imposed to reduce the use of petrol-based and non-renewable  components . A possible solution to this issue is the replacement of the thermoset matrix with recyclable or renewable matrices. However, thermoplastic composites cannot be an effective solution since they are characterized by lower mechanical properties, thus not ensuring the required level of strength and safety in most structural applications [8].
