The status of PEEK in the field of aerospace

The status of PEEK Machined Parts in the field of aerospace?

In a market like aerospace, where the cost of just building a new aircraft can add up to millions of dollars and man-hours, a company will only start to see a return on investment after five to ten years, if at all. With such time spans and costs so high, aerospace companies are constantly looking for ways to make their planes lighter, more fuel-efficient and cost-effective for potential buyers.

One way airlines such as Boeing and Airbus are achieving these goals is by turning to specialty materials such as PEEK to reduce weight while still retaining the properties of metal. Developed in the 1980s, PEEK (POLYETHER ETHERKETONE Machined Parts ) is a thermoplastic belonging to the PEEK family that is heat-resistant, has little reaction to harmful chemicals and radiation, and has tensile strength and load strength comparable to titanium and steel.

The strengths of PEEK lie in its mechanical resistance properties, heat resistance and chemical lightness, essential characteristics in fields such as aerospace, where weight reduction reduces consumption and emissions and improves aircraft efficiency. Reduced weight: The density of PEEK is 1.3g/cm3, less than half that of aluminum (2.7g/cm3). Furthermore, thanks to its unrivaled chemical resistance, components made of PEEK can withstand mechanical stress even in chemically aggressive environments without loss of mechanical properties and without the corrosion phenomena commonly seen in metals.
