The use polymer-based materials
and coatings in aircraft components is two-fold, first, the weight reductions
are highly desirable to decrease fuel consumption and second, polymer-based
materials are usually less expensive and convenient to manufacture. However
when used in applications with strict optical requirements, these polymeric
surfaces can be susceptible to erosion which results in increased haze and
decreased clarity. For example, when staple materials such as polycarbonate or
stretched acrylic are used in windows, windshields and canopies, one of the
drawbacks is the tendency to scratch and craze. Polymeric windows have been
historically coated with polysiloxane or polyurethane
based coatings to overcome this limitation by improving the surface resistance
to scratches. Still, improvements to the processes involved can decrease the
required long drying times and can offer long term solutions in which the
resistance to erosion is maintained overtime. Advanced thin film coatings based
on Open Air Plasma Deposition Technologies can improve the durability of many
components on aircrafts. These technologies can be exploited to generate
materials with high performance, which are also environmentally friendly and
produced with waste free processes. We are currently focusing our efforts in
the development and study of thin films to improve the resistance to material
erosion on polymeric substrates with applications in the aerospace industry and
