Can you cut fiberglass with a CO2 laser?

When it comes to cutting strong, composite materials like fiberglass, many manufacturers ask the same question:

Can a CO₂ laser handle it?

The answer is — yes, but with caution.

⚠️ What Is Fiberglass and Why It's Challenging

Fiberglass is a reinforced plastic material composed of woven glass fibers embedded in resin. It’s widely used in automotive, aerospace, construction, and marine industries due to its lightweight, high-strength, and heat-resistant properties.

However, fiberglass presents certain challenges for laser cutting:

Glass fibers can reflect or scatter the laser beam

The resin can release toxic fumes during vaporization

Cutting edges may darken or produce fine dust particles

That’s why proper machine settings, ventilation, and safety protocols are critical.

✅ Can CO₂ Lasers Cut It?

CO₂ lasers can cut fiberglass — especially thin sheets or fabric-based fiberglass — with high speed and moderate precision. The key is to balance:

Lower power levels (to prevent charring)

Slower cutting speeds (to maintain accuracy)

Efficient exhaust systems (to remove smoke and fumes)

ARGUS LASER machines can be configured to handle light-duty fiberglass cutting tasks. However, for thicker or industrial-grade fiberglass, we often recommend mechanical cutting or waterjet systems instead, depending on your production goals.

️ Important Notes on Safety

Laser cutting fiberglass can release harmful particulates and fumes, including potentially toxic substances like styrene or formaldehyde from resin binders. For this reason:

Always operate in a well-ventilated space

Use fume extraction and filtration systems

Consider protective eyewear and gloves during post-processing

Safety should never be compromised — and our team at ARGUS is here to help you assess the risks and configure the safest system possible.
