WitrynaAt normal impact and at lower impinging velocity (i.e. 80 m/s), a mass gain in the initial period was observed for all the materials except material G (material G was the only amorphous PA in the selec-ted series of PAs). At higher impinging velocity (140 m/s), however, three materials, namely C, E and G, did not show initial mass gain.
