Carbon fiber materials are so ubiquitous in everyday life, their lightweight composition and incredible strength help composites excel in a variety of applications, including the aerospace, marine and sporting goods industries. The same properties that make carbon fiber useful in so many applications can make the material difficult to cut. Super-strong fibers require tough blades; lightweight fabrics woven from carbon fibers twist easily; and due to their high conductivity, lightweight dust can become airborne, wreaking havoc on nearby electronics.
Small or start-up facilities may be inclined to cut carbon fiber using everyday tools such as tile cutters or jigsaws. However, these methods cannot provide the tight tolerances required by aerospace, civil engineering and other industries that benefit from the unique properties of carbon fiber. Since carbon fiber is an expensive raw material - even compared to other composite materials such as glass fiber - precise cutting and reliable solutions become even more important.
Carbon Fiber Cutting Method
Deciding how to cut carbon fiber at your facility depends largely on the quantity and quality you need for your final product. For more information on the right cutting solution for your application, please contact an application specialist at AOL. Our team is proficient in cutting dry and pre-preg composite materials, including carbon fiber.
manual cutting
Tissues that cut small amounts of carbon fiber can rely on manual cutters. Depending on the application, rotary shears, straight or round knives may provide an acceptable cut at an economical price.
Automatic cutting
Digital cutting machines provide the precise cutting, high speed, and automated methods required by many facilities that cut carbon fiber. Autocut also offers businesses the ability to customize their cutting machines. AOL's tool heads, for example, can be equipped with two or three tool spindles that typically cut dry carbon fiber with circular knives to crush and break the fibers. The 10-sided blade provides strength and versatility for cutting multi-axis carbon fiber cloth. Provides fast, accurate cuts while reducing sticking and friction when cutting adhesive-backed composites.
The high conductivity of carbon fiber particles can affect delicate electronics that are critical for automated cutting. AOL's digital cutting solutions are designed to perform well in all types of production environments, from clean rooms to harsh or high particle environments. The controls and operating computers for each machine are housed in separate cabinets, utilizing positive air pressure to keep carbon fiber dust out. This protection technology keeps controls and computers safe from dust and water in facilities where dry carbon fiber is cut. Wiring connectors, servo motors and display components also meet industry-standard international protection ratings.
Carbon Fiber Cutting Tips
1. Use the correct blade
Carbon fibers are strong and abrasive, making cutting them a potential challenge. Choosing the right cutter and the right blade for your application can minimize costly scrap. Blades designed for cutting carbon fiber are usually made of tungsten, carbide, diamond, and other very durable materials.
2. Avoid common problems
Many businesses are familiar with the difficulties associated with cutting strong, lightweight composite materials, including carbon fiber. To find the best carbon fiber cutting machine for your product, look for a system that addresses delamination, burrs, and overheating.
3. Preparation of Carbon Fiber Dust
Dry carbon fiber creates dust when cut. This dust has the potential to damage electronic equipment, irritate the operator's lungs and burn. While each of these situations can be easily avoided, they require proper preparation and the right equipment.
