Additives and Reinforcements for Composites

Manufacturer part: 5467N15

Mix these additives with melted plastic, epoxies, or adhesives to make parts stronger and more wear resistant without adding much weight. You can use them in batches to tackle repairs and small parts instead of machining your part from a sheet, bar, or other shape.Carbon Fiber and Recycled Carbon FiberOften used in vehicles to increase fuel efficiency, these additives can double your composite’s strength to make stiff pieces that are stronger and lighter in weight than aluminum. The more you add to your mixture, the stronger it becomes. These additives also carry electric currents, so they’re good for directing electromagnetic energy away from electrical devices. However, they don’t direct electricity as well as metal. They’re made of chopped fibers, which makes them ideal for repairs and intricate parts. But, they’re not as strong or as stiff as materials with continuous fibers, such as fabric and tow.The size of carbon fiber’s particles affects its ease of use and strength. The smaller the particle size, the less effort it requires to mix. On the other hand, larger particles make parts stronger and stiffer. Choose carbon fiber with smaller particle sizes when making intricate parts and repairs.Carbon fiber additives for thermosets mix with epoxies, adhesives, vinyl compounds, and phenolic. Use compression molding to turn your mixture into parts, or fill in cavities after curing without adding weight. You can’t shape your product once it’s cured. Begin with 5% by volume in your mixture.
