CRP Technology has announced that its Windform family of high performance composite materials has been rated HB according to the flammability UL 94 test, and has also been exposed to vacuum ultraviolet radiation and did not show degradation.

Windform’s thermal and mechanical properties make them a highly suitable Laser Sintering material for applications such as UAV (unmanned aerial vehicle) frames and other components.

Laser Sintering polyamide-based carbon fiber reinforced Windform XT 2.0 and Windform SP composite materials, along with LS polyamide-based glass-fiber reinforced Windform GT and Windform LX 3.0 composite materials, were tested for their flammability rating.

The “Test for flammability of plastic materials for parts in devices and appliances” UL 94 was carried out on test specimens 1 to 3 mm thickness. The result of the flammability UL 94 HB test reports Windform XT 2.0, Windform SP, Windform GT and Windform LX 3.0 have successfully obtained the HB classification.

Samples of Windform LX 3.0 and Windform SP 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”.
