Fiber reinforced polymer composites are exceptional alternatives to traditional materials such as wood, ceramic, and metal, enabling designers to create lighter weight structural components for increased lifetime performance, and improved fuel efficiency. In combination with other materials, CFRTP materials can be integrated and positioned locally where needed to achieve structural performance requirements. Processing conditions can cause material properties to shift from the values stated in the information.
