Polymer matrix composites are created by mixing glass or carbon fibers in an epoxy or urethane resin. Because material properties are engineered specifically for an application by specifying a resin and the layout of the fiber (random, woven, etc.), the resulting “board” offers exceptional strength in a lightweight package.

Our cutting setup consisted of an XY table where the beam is directed to the focusing lens through a set of “flying” turning mirrors. For focusing, we choose a 2.5” positive meniscus lens that provides a 100-micron (0.004”) spot size with a 1.8 mm (0.07”) depth of focus. We used 60 PSI of CDA (clean, dry air) as an assist gas.

Vinyl (also known as poly vinyl chloride or PVC) is one of those ubiquitous materials seen everywhere in modern life, in part because it is both water- and flame-resistant. At one end of the vinyl spectrum are products such as wire insulation, vinyl siding, and PVC pipe; the other end of the spectrum includes vinyl shoes, raincoats, and upholstery. Vinyl fabric is used in many outdoor applications, especially when exposed to the elements where UV and mildew/water resistance is important. This category includes seats and cushions for outdoor furniture, boats, automobiles, and ATVs.

All of these vinyl products exhibit one similarity – they provide a nicely contrasting image when marked with a CO₂ laser. In the past, we have shown contrasting marks on various types of PVC and PVC-coated products including tubing and wire insulation. As shown in the accompanying photo, vinyl fabric demonstrates the same high-visibility, high-contrast mark.
