Windform materials withstand ultraviolet exposure

Windform materials withstand ultraviolet exposure

12nd April 2018

Samples of Windform® SP and Windform® LX 3.0 were exposed to vacuum ultraviolet radiation and they did not show degradation. The results confirm Windforms are the most appropriate composite materials for high demanding sectors.

Vacuum ultraviolet exposure (VUV testing) is performed to understand how a material will withstand the damaging effects of ultraviolet exposure.
Samples of Windform® SP (polyamide-based carbon fiber reinforced composite material from Windform® family of high performance advance materials for Laser Sintering technology) and Windform® LX 3.0 (polyamide-based glass fiber reinforced composite material from Windform® family of high performance advance materials for Laser Sintering technology) were subjected to VUV testing by exposing to ~8 solar equivalents in LEO, with a wavelength range of 115-200 nm VUV radiation from a 30 W Hamamatsu L7292 deuterium lamp for 36 continuous hours.

Test results report "Windform® SP and Windform® LX 3.0 samples did not show degradation with VUV testing. There was clearly no measurable erosion with the profilometer, and any microscopic effects that might have been measurable by SEM were within the inherent surface roughness of the material and were therefore not observable by this technique".

The results confirm Windforms are the most appropriate composite materials for challenging and harsh applications.

Results can be looked up on our website on the Windform page for Additional Test Results.
