SMC Hycomp™ H310®

Overview
These proprietary polyimide-based sheet molding compounds (SMC) are formulated for aviation-critical mechanical components where metal alternatives are sought for weight reduction and thermal performance. Designed for continuous operation up to ~315°C (600°F) with service condition data up to +320°C, they are suitable for components exposed to high temperatures and heavy mechanical loads.

Material Variants

• H310®: Thermoset polyimide resin reinforced with 1 in (25.4 mm) chopped carbon fiber — optimized for high mechanical load-bearing applications at lower to moderate sliding speeds.
• H320®: Thermoset polyimide resin reinforced with 1 in (25.4 mm) chopped glass fiber — intended for high-temperature heat-shielding and electrical insulation uses.

Key Benefits

• Continuous operating capability up to ~315°C (600°F).
• High mechanical strength in service (typical value ~710 MPa).
• Significant weight saving versus metal alternatives (up to ~40% in some applications).
• Tribological properties that can reduce or eliminate the need for lubrication in many wear applications.
• Manufactured as sheet molding compound for repeatable, consistent parts and predictable processing.

Notes on PFAS
PFAS-Free* — PFAS are not intentionally added to the product; trace environmental presence is not excluded.
