They may be injection molded plastic but that does not mean they are weak. Bringing lighter weight and impact resistance to metal applications, engineered plastics are likely to be increasingly taking the place of traditional materials.
Injection molding is the ideal process to produce complex aircraft components such as this outlet guide vane fairing
THE AEROSPACE INDUSTRY is continuing to evolve and there is a long-term trend toward using more engineered injection molded and machined parts in aircraft. According to Stratistics MRC the global aerospace plastics market accounted for 12.32 billion USD in 2017 and is predicted to reach 26.79 billion USD by 2026; an annual growth rate of 9%*.
The same report points to the main drivers as a rise in the number of aircraft manufactured, increasing demand for lightweight components and growing demand for plastics in several aerospace applications. However, the high cost of fabrication and a limited range of material options are hampering the market.
“There are numerous advantages associated with ultra, high performance, and engineered polymers.”
