Garolite Material: The Ultimate High-Performance Fiberglass Epoxy Laminate
2025-04-29

Garolite material, commonly designated G-10, is a high-pressure fiberglass epoxy laminate prized for its blend of mechanical toughness, dimensional stability, electrical insulation, and chemical resistance. It is fabricated by stacking woven glass-cloth plies, impregnating them with epoxy resin, and then curing under heat and pressure to form rigid sheets. This process yields a lightweight yet durable composite used across electronics, industrial, aerospace, and maker domains. Read More
