ZOLTEK’s™ Pultruded Profiles are pre-cured, thick-ply carbon fiber laminates for ideal structural reinforcement applications. Available in a variety of thicknesses and complex shapes, our pultrusion products deliver optimized properties with high fiber volumes, nearly zero void content, and locked-in filament alignment.

ZOLTEK PX35 carbon fiber tows are fed into our proprietary impregnation and curing process which creates smooth carbon fiber laminates resulting in efficient laydown when building thickness. The specific fiber alignment achieved with pultrusion delivers consistently better overall properties in laminates than any other composite manufacturing process. Depending on the end application, these pultruded profiles are typically produced with a thermoset epoxy or vinyl ester resin in a proprietary low-cost, high-throughput process.

Pultruded profiles are production-ready carbon composites for infrastructure applications, deep sea exploration, wind energy, and other applications benefiting from the unique properties of pultruded carbon fiber parts.

 

Applications: Wind Energy, Infrastructure, Offshore Drilling, Mining, Other Structural Reinforcement Applications

·         Specific gravity (relative density): 1.6(H2O@ 4°C= 1.00)

·         Solubility(ies): water: not soluble

·         Auto ignition temperature: 300–400°C

·         Decomposition temperature (in Air): 150–200°C

·         Reactivity: Avoid reactions with strong oxidizing agents. The fine dust from a carbon fiber compound or composite that is cut or formed can create additional dust explosion risk depending on the resin or compounding agent

·         Chemical stability: stable under normal ambient and anticipated storage and handling conditions of temperature and pressure

·         Possibility of hazardous reactions: Avoid reactions with strong oxidizing agents. The fine dust from a carbon fiber compound or composite that is cut or formed can create additional dust explosion risk depending on the resin or compounding agent

·         Conditions to avoid: No special measures necessary if used correctly. Carbon fiber composite coils are under tension –do not cut banding without proper coil release controls. Dust may form an explosive mixture with air when processed. Keep away from sources of ignition and refrain from smoking in the vicinity. Carbon fiber composite dusts are electrically conductive. Electrical equipment, enclosures, circuits and power tools in or near areas where carbon fiber composite are handled should be protected against infiltration or contact with airborne particles or filaments. Avoid breathing dust, vapors, and gases from after-treatment processes (e.g. grinding/cutting/drilling). Ensure well-ventilated area for such activities.

·         Incompatible materials: Avoid reactions with strong oxidizing agents. The fine dust from a carbon fiber compound or composite that is cut or formed can create additional dust explosion risk depending on the resin or compounding agent

·         Hazardous decomposition products: No hazardous decomposition products will be formed during normal usage of carbon fiber composites. Complete or partial combustion may generate COx, NOx, and other trace chemicals.
