How to Cut Glass Epoxy Sheet?
Glass-epoxy (often referred to as FR-4, G10, or “epoxy fiberglass laminate”) is a composite material made from woven glass fibers impregnated with epoxy resin. It’s widely used in electronics, structural parts, insulation panels, and prototype work. Because the glass fibers are abrasive and the epoxy matrix is somewhat brittle, cutting this material requires care, the right tools, and protective measures.
