Machining Methods for Perforating Composites

Traditional Perforating Methods and Precision Abrasive Machining
When it comes to perforating composite materials such as fiberglass, carbon fiber, Kevlar and ceramic matrix composites, there are four options: CNC Drilling, Waterjet Drilling, Laser Drilling, and Precision Abrasive Machining (PAM). Which method you choose will determine the quality of your perforations.

Limitations of Traditional Perforation Methods

Traditional machining methods such as CNC Drilling, Waterjet Drilling and Laser Drilling have their limitations when perforating composite materials. These challenges can impact the ability to meet customers expectations such as hole/slot size uniformity, lack of burrs and loose fibers, no delamination or distortion, and no lost or missing holes/slots.

Non-homogeneous materials used in traditional perforation methods can cause a thermal mismatch and delamination between layers. Often times these methods require a secondary process to remove burrs and loose fibers. Here are some of the limitations of traditional machining methods:

CNC Drilling Limitations:

  • • Burrs
  • • Wall Tearing
  • • Loose Fibers
  • • Delamination
  • • Need Secondary Process


Waterjet Drilling Limitations:

  • • Delamination
  • • Loose Fibers
  • • Size Uniformity
  • • Swelling (wet)
  • • Hard to Repair


Laser Drilling Limitations:

  • • Thermal Mismatch
  • • Delamination
  • • Burnish (heat)
  • • Hard to Repair

Benefits of Precision Abrasive Machining

At IKONICS Advanced Material Solutions we use a non-traditional machining method called Precision Abrasive Machining (PAM) to create perforations and patterns in composite materials. This unique perforation method can produce a variety of precise features, shapes and/or perforations in advanced materials while imparting virtually no stress or damage to the material.

Benefits of our PAM Process include:

  • • Clean Entry and Exit
  • • No Burrs
  • • No Fibers
  • • Process is 100% Dry
  • • Same Results with Any Shape (oval, square, slots, etc.)

AMS Will Be Presenting at CAMX

CAMX is the largest, most comprehensive composites and advanced materials event for products, solutions, networking, and advanced industry thinking. We are honored to not only be exhibiting at this show, but also to present at it.

Join us September 24-26 in Anaheim, CA for a comprehensive look at the different machining methods for perforating composites. Wes Barton, Senior Application and Sales Specialist for IKONICS AMS, will be giving an in-depth presentation on the benefits of the PAM Process over traditional machining methods.
