Sheet polyimide H310®

aeronautical

Overview
These proprietary Hycomp™ composite materials are sheet molding compounds (SMC) engineered as high-temperature, polyimide-based composites reinforced with one-inch chopped carbon (H310®) or glass (H320®) fibers. Designed as metal replacements to reduce weight and remove lubrication requirements in demanding mechanical and aerospace-critical systems, they provide high mechanical strength and continuous operating capability up to approximately 315°C (600°F).

Applications

• Engine components
• Flight control parts
• Landing gear
• Wheel and braking systems
• Bushings
• Guide rings
• Wear liners
• Seals
• Clamps
• Thermal isolators

H310® Composite (key points)

• Aerospace-grade polyimide thermoset resin reinforced with one-inch chopped carbon fiber.
• Optimized for lower to moderate speeds with high-load capability.
• High mechanical strength suitable for structural and wear-critical components.

H320® Composite (key points)

• Polyimide thermoset resin reinforced with one-inch chopped glass fiber.
• Best suited for high-temperature heat shield applications and high-temperature electrical insulation.

Advantages

• Continuous operating temperature capability up to approximately 315°C (600°F).
• Significant weight reduction versus metal in many applications (up to ~40% in some cases).
• Eliminates or reduces the need for lubrication in many mechanical assemblies.
• High mechanical strength and suitability for aviation-critical systems.
