Composites such as fiberglass are nothing short of miracle materials. Its physical strength is on another level. This high strength is why fiberglass has found so many applications, replacing a wide range of materials.

However, this high strength also poses a challenge for manufacturers and fabricators. Professionals in the industry often wonder about the best method to cut materials such as fiberglass. Its physical characteristics (strength and hardness) render ordinary cutting methods unfeasible.

As a result, waterjet cutting has become the most sought-after option for cutting fiberglass and similar material. In this article, we will investigate waterjet cutting fiberglass in detail.

Can You Cut Carbon Fiber and Fiberglass With a Waterjet Cutter?

Yes, an abrasive water jet cutter can cut any type of material, soft or hard. The wide range of materials that can be cut by waterjet include:

  • Fiber Reinforced Plastic (FRP)
  • Glass Fiber Reinforced Plastic (GRP or GFRP)
  • Carbon Fiber Reinforced Plastic (CFRP or CRP)
  • Carbon Fiber Reinforced Carbon (C/C)
  • Composite Foams
  • Composite Papers
  • Metal Matrix Composites
  • Ceramic Matrix Composites
  • Any type of carbon fiber

It is important to note that these are only a few examples of what waterjet cutting is capable of. If you have any other composite material that requires cutting, a waterjet cutter can process it without hassle.

What are the Benefits of Using a Water Jet to Cut Composites Like Fiberglass and Carbon Fiber?

Many benefits make water jet cutting the best choice for cutting materials like fiberglass and tough carbon fibers. Some of these factors are:

High-Quality Parts

Waterjet cutting is highly accurate, leading to high-quality parts. Precision machining by water jet cutter also allows parts to be used without needing any secondary finishing, as there is a smoother finish with a water jet.

Other cutting alternatives can often cause delamination of carbon fiber and create rough surface edges. This does not happen with waterjet cutting.

No Heat-Affected Zones

When cutting hard materials, most cutting tools generate a lot of heat that can ruin the material near the cut location. These hot zones can degrade material integrity and its visual appearance.

However, high-pressure water jet cutting is a cold-cutting process. Therefore, no heat-affected zones are created. The jet of water is itself heat dissipating in nature.

Dust Free Cutting

Cutting carbon fiber materials with blade cutters or other cutting tools generates carbon dust in the environment. This dust is harmful to health and also hinders operation. However, waterjet cutting includes dust containment, as all the dust generated is dissolved and washed away as the jet of water cuts through the material. Therefore, the environment is entirely dust-free.

Workforce Safety

Most composite cutting tools bring safety concerns, such as the risk of potential injury to the workforce. However, waterjet cutting ensures complete workforce safety. Additionally, the cutter is controlled by a CNC machine, and the operator doesn’t have to physically handle the cutting head. This means that there is not even the slightest possibility of injury.

Environment Friendly

Pressurized water jet cutting is a green process. There is no emission of toxic fumes or harmful waste substances. Even the carbon fiber dust generated as a waste material can be strained and used as an abrasive for abrasive waterjet cutting. Additionally, the water itself can be recycled back into the system.

Versatile Shapes and Thicknesses

Waterjet cutting can create a wide range of cut shapes, from simple two-dimensional cuts to intricate and complex 3D cuts. There are multi-axis water-jet-cutting machines available for this purpose. Additionally, it supports any thickness of composite material sheets.

Production Rate

The water-jet-cutting process has fast production rates. When cutting consistent shapes, multiple sheets of composite materials can be stacked on top of each other and cut simultaneously. This stacking process scales up the production speed exponentially.

Cost Saving

Water jet cutting is one of the most cost-saving cutting methods for fiberglass. It offers low tooling costs (the water is recycled), high production rates, and no material wastage due to the absence of heat-affected zones. Additionally, stacking multiple carbon fiber layers provides another advantage in saving costs.

Material Saving

Waterjet cutting has minimal kerfs, which means that negligible material is removed during the cutting process. Additionally, since there are no heat-related effects and accuracy is high, the defect rejection rate is low. This makes waterjet cutting the best material-saving cutting option.

Applications of Waterjet Cutting of Composites

There are many applications of water jet stream cutting, such as:

  • Insulators: Composite materials are used to make insulators for power generation and distribution. These insulators are often cut using a waterjet cutting machine.
  • Communication Enclosures: Composite sheets form communication enclosures to provide a single contact point for all communication terminals and protect them from harsh natural elements.
  • Aerospace: The aerospace industry requires various composite materials for parts, such as thermal heat insulation. These have extreme hardness and are cut using a waterjet cutter for ultra-high precision.
  • Signage: Water jet cutting is ideal for PVC acrylic composites to create various forms of signage.
  • Heat Sink: Heat sinks for electronics and industrial equipment are produced using a waterjet cutter.
  • Heat Transfer: Heat transfer solutions made of silicone and neoprene laminates are processed with a waterjet cutting solution.
  • Automobiles: Fiberglass is an integral part of automobile body kits and components. It is present in multiple locations in each and every car.
  • Sports Gear: Waterjet-cut carbon panels are used to make a variety of sports gear, such as tennis racquets, archery bows, and golf clubs.

How to Choose a Water Jet Cutter for Composites?

When deciding on a water jet-cutting machine, it is important to evaluate the decision based on the following factors:

  • Pump Pressure: The water pressure of the water tank will play a key role in the cost of the water jet cutting machine. Hard materials like strong carbon fibers require a high water pressure, so choose the particular machine based on the type of materials you want to cut and their thickness.
  • Build Quality: The build quality of the equipment is very important to consider because waterjet cutting machines are a significant investment. It is better to spend slightly more on superior build quality than to compromise in this regard. Even a minor breakdown of parts like a vacuum assist valve can cause significant downtime, so focus on getting high-quality machines.
  • Features: There is a wide range of features that you can get with a waterjet cutter, such as underwater cutting and software control. Many of these features are indispensable, providing a better cutting experience and higher cut quality and saving costs in the long run.
