Carbon Fiber Pultrusion: Speed, Temperature, and Resin Selection Guide for High-Performance Profiles

Carbon fiber pultrusion runs at 100-300 mm/min with 60-70% fiber volume fraction — roughly double the glass content achievable in hand lay-up. The trade-off: a 12K carbon tow costs $20-30/kg versus $2-4/kg for E-glass roving, and the die wear rate on carbon is 3-5X higher because carbon fibers are abrasive. You don’t choose carbon pultrusion […]
Carbon Fiber Pultrusion Die Design: Steel, Tolerances, and Heating Systems

Pultrusion die tooling accounts for 15-25% of a new production line’s capital expenditure — yet most cost overruns come from dies that wear out in half their expected life or fail to hold ±0.1 mm tolerances on the first production run. A steel die for a 50 mm × 6 mm carbon fiber flat bar […]
