How Does Waterjet Cutting Carbon Fiber Work?

Waterjet cutting is a versatile method for cutting various materials, including carbon fiber. The process involves using a high-pressure stream of water mixed with an abrasive material to cut through the carbon fiber precisely. Here’s how it works: 

High-pressure Water Supply

The system includes a high-pressure pump that pressurizes water to extremely high levels, typically between 30,000 to 90,000 pounds per square inch (psi).

A thin stream of high-speed water is enough to cut through carbon fiber and other similar composite materials.

Abrasive Material

In waterjet cutting carbon fiber, an abrasive material is usually added to the water stream to enhance the cutting ability.

Standard abrasives used include garnet, aluminum oxide, or diamond dust. A mix of abrasives increases the cutting efficiency of waterjet cutters.
