Atlas Fibre maintains North America’s largest in-stock inventory of thermoset composite rods - available for immediate shipment or in-house machining. From precision engineering to production-scale readiness, Atlas Fibre supports projects of every scope.
Composite rods can be manufactured through two primary methods — ground sheet rod and rolled and molded rod. Each method has distinct performance characteristics and advantages, and our experts can help you determine which rod type aligns best with your engineering requirements for strength, precision, and cost. Read more and explore the material options below.
Ground Sheet Rod (“Sheet Rod”): Ground sheet rod begins as square bars cut from thermoset composite sheets. These bars are precision ground to achieve circular outside diameters and cut to length.
Rolled & Molded Rod: Rolled rods are produced by rolling prepreg into a tube and compressing it into a mold, creating a dense, highly uniform structure.
Glass Epoxy Rods (G-10, G-11, FR-4)
High Strength & Stability: Exceptional mechanical strength, outstanding electrical insulation, and proven performance across wide temperature ranges.
Linen Phenolic Rods (L, LE): Fine Weave Precision
Smooth machining characteristics and improved electrical properties in LE grades.
Canvas Phenolic Rods (C, CE): Durable & Impact Resistant
Tough, resilient material suitable for structural and mechanical applications, with CE grades delivering enhanced electrical insulation.
Glass Melamine Rods: Heat & Arc Performance
Engineered for applications requiring strong arc resistance and dimensional stability at elevated temperatures.
Glass Silicone Rods: Temperature Resilience
Excellent thermal endurance and electrical insulation for demanding environments.
Whether your goal is structural strength, electrical insulation, machinability, or thermal stability, Atlas Fibre ensures you receive the optimal rod grade and manufacturing method for your application.
The ideal rod material depends on the demands of your application, including:
Thermal Environment: For cryogenic or sub-zero environments, select materials engineered for low-temperature stability. For high-heat environments, choose grades with elevated thermal tolerance.
Mechanical Strength: Structural applications often require material with high flexural and tensile strength. Our material data sheets provide detailed performance criteria for comparison.
Electrical Insulation: Different rod grades offer varying levels of electrical resistance, making material selection essential for high-voltage or insulating applications.
If you need assistance evaluating performance criteria, our technical specialists can guide you to the most effective material and rod type for your exact specifications.
All rod materials can be cut to size to support your machining and production needs.
Atlas Fibre stocks a wide selection of high-performance thermoset composite rods – ready to ship and ready for fabrication. Request a custom quote today or speak with our expert team to identify the right rod material and manufacturing method for your application.
