Yellow glass epoxy laminate sheets are composite materials primarily composed of woven fiberglass cloth impregnated with a yellow-tinted epoxy resin system. The fiberglass provides high mechanical strength, excellent dimensional stability, and good resistance to heat and moisture, while the epoxy resin acts as an insulating binder that gives the sheet its rigidity and dielectric properties. The yellow coloration is typically achieved through the addition of pigments or specific resin formulations, and in some cases, the sheets may also include flame retardant additives to meet safety standards like those of FR-4 grade materials. These sheets are widely used in electrical insulation, printed circuit boards, structural components, and various industrial application.
