Thermosetting compounds as substitutes for automotive steel

Thursday, 31 October 2019 14:58

Thermosetting compounds are formed using fiberglass, carbon or aramid, which is combined with resins such as polyesters, vinyl esters, epoxies or phenolic resins. These compounds are used in various sectors, but they stand out in particular in the manufacture of aircraft or spacecraft parts.

Thanks to the research and development in the aerospace sector, the compounds are also used in other forms of transport due to the high demand for vehicles and light components. This trend seeks to use innovative materials to reduce the weight of products. Therefore, composite materials are increasingly used for automotive parts and components.

According to the American associations of composite manufacturers, fiberglass is one of the most important reinforcement materials in the thermosetting industry. Due to its resistance properties, it constitutes an excellent substitute for steel in structural components of the vehicle, such as drive shafts, dampers or roof beams.
