Evaluation of Barrier Materials: Metal Alloys, Fibers, and Plates.
Abstract
The resistance of various commercially available lightweight materials to CO2 laser damage was examined. Five samples were supplied for laser evaluation: (1) D242, a needle punched and rolled alloy fiber, (2) 304SS stainless steel fibers web sintered and rolled, (3) 430SS, a stainless steel sinter on hard backing, (4) FM515 with Inconel 600 backing, and (5) a graphite woven cloth. A 100 W CO2 laser beam was focused to provide various irradiance levels up to 6.7 KW/sq cm. These samples may be exposed safely at about 20 watts/sq cm. For kilowatt level exposures, dark finished samples are more robust than bright finished samples of the same material. At 6.7 KW/sq cm, all materials are penetrated in less than one second with the exception of 430SS and DH242 wet with water. (Author)
