5 Common Applications for Laminated Sheets
Laminated sheets are made of a substrate such as fiberglass cloth, carbon fiber cloth, canvas, linen, and paper mixed with a resin.
CURRENT, INC. has been manufacturing Laminated Sheets for decades. Our Laminated Sheets are made out of thermosetting resins including Phenolic, Melamine and Epoxy. We also manufacture Carbon Fiber Laminated Sheets. The base materials we use to create our Laminated Sheets include: glass fabric, cellulose paper, or cotton fabric as well carbon fiber. These various substrates are impregnated, “B Staged”, with our resins, and then pressed under heat and high pressure. This process produces a dense homogeneous material, that is easy to tap, saw, drill, and machine.
CURRENT, INC. manufactures their Laminated Sheets in assorted colors and sizes for the convenience of customers, and are equipped to make sheets up to 102” long. Depending on the grade chosen, Laminated Sheets are anywhere from .0.005”-3.000” thick. All tolerances meet NEMA standards, but clients are welcome to contact our sales office to get in-depth details on specific tolerances. For closer tolerances we can also offer surfacing grinding.
We can provide custom fabrication upon request, this includes a cut to size. Our quotes are free with no obligation to purchase. All we need is your blueprints and/or specs to provide an accurate quote. For further information or to obtain a quote, you can contact us through :

Current Inc. manufactures laminated sheets engineered for strength, stability, and consistent machining performance. These sheets are produced using thermosetting resin systems, phenolic, melamine, epoxy, and carbon based formulations, combined with reinforcement materials such as glass fabric, cellulose paper, wood veneer, cotton fabric, Kevlar aramid, and carbon fiber. Each substrate is resin impregnated, B staged, and pressed under controlled heat and pressure to create a dense, uniform laminate suitable for demanding industrial environments.
Laminated sheets are available in a wide range of colors, grades, and thicknesses to support electrical insulation, mechanical components, structural parts, and specialty applications. Standard thicknesses range from 0.005″ to 4.000″, with sheet sizes including 36″ × 48″, 48″ × 48″, 48″ × 72″, and 48″ × 96″. Special sizes up to 102″ are available for large format requirements. All sheets meet NEMA tolerance standards, and surface grinding is available for applications requiring tighter dimensional control.
Current Inc. provides full machining support for laminated sheets, including cutting, milling, drilling, tapping, routing, turning, and sanding. Sheets can be supplied cut to size or fully fabricated to print. Customers may submit blueprints or specifications for quoting, and our team will configure materials and tolerances to match project requirements.
Laminated sheets offer strong heat resistance, high tensile and impact strength, stable electrical properties, and predictable machining behavior. Depending on the grade, these materials support insulation, structural reinforcement, wear resistance, and chemical exposure requirements. Carbon fiber sheets provide lightweight strength for aerospace, marine, and performance driven applications, while paper and cotton based laminates support electrical and mechanical uses.
Current Inc. supplies laminated sheets in multiple NEMA grades, including X, XX, XXX, C, CE, L, LE, G 3, G 5, G 9, G 10, FR4, G 11, and FR5. Each grade offers distinct mechanical, electrical, and thermal characteristics suited for gears, bearings, insulators, spacers, bushings, structural panels, transformer components, circuit board fixtures, and high temperature assemblies.
Laminated sheets can be used for bushings, gears, bearings, pulleys, spacers, gaskets, wear blocks, terminal boards, slip rings, rotor vanes, insulators, thrust washers, arc chutes, coil forms, antenna bases. These products are NEMA grade quality and can be trimmed to any size.
