CUTTING ARAMIDS AND KEVLAR USING A LASER

Laser cutting is among the most popular processes in the industrial sector, especially when complex designs and details need to be processed as quickly as possible and without the exertion of any force. Almost any material can be processed quickly and easily using the efficient and precise lasers from JustLaser. Benefit from a JustLaser Laser Cutter when cutting aramid and Kevlar with a laser and be won over by the high productivity at a relatively low investment risk.

WHAT ARE ARAMIDS AND KEVLAR?

Aramids – shorthand for aromatic polyamides – are liquid crystal polymers (LCP), which are mostly manufactured as fibres in the form of film, paper or particulates. They are characterised by their golden yellow colour. Aramids are high-tensile fibres that are resistant to high temperatures, and can even withstand temperatures in excess of 370 °C. The material is divided into meta-aramids, para-aramids and para-aramid copolymers. Kevlar is part of the group of para-aramids and was developed by Dupont in 1965. It is known for its high strength and relatively low weight.

The efficient laser machines have definitely proven themselves as the right choice for cutting aramids and Kevlar as they can cut and sever the special material extremely precisely.

 

THE AREAS OF APPLICATION FOR ARAMID AND KEVLAR

Aramid and Kevlar are very strong and resistant to acids, alkaline solutions and heat. The material is also distinguished by its low weight. Aramid is often used in the security sector and is principally used for reinforcing textiles – either as protection around the body or to increase the lifespan of items of clothing. Typical applications of aramid are:

  • Bulletproof vests
  • Cut-resistant clothing
  • Splinter protection
  • Protective helmets
  • Protection against fire, e.g. for protective suits for the fire brigade
  • Lines for paragliders
  • Sails for sailing boats
  • Bike tyres
  • Kevlar reinforcements for bike clothing, motorbike clothing and motorsports clothing
  • Technical components in vehicle construction, e.g. for armour plating
  • Aircraft construction, e.g. for the engine cowling of jet engines
  • Seals
  • Electrical insulation, etc.

HOW DOES LASER CUTTING WORK?

Laser cutting is a thermal cutting process in which the material in the cutting gap is vaporised by the heating effect of a laser beam (= sublimation cutting). In this process, a precise laser beam traces the indicated patterns and cuts through the material in the desired design. There are three different methods, depending on the thickness and the material: laser flame cutting, laser fusion cutting and sublimation cutting. You’ll find the ideal laser machines for cutting aramids and Kevlar with a laser at JustLaser.

THE BENEFITS OF CUTTING ARAMID AND KEVLAR WITH A LASER

THE BENEFITS OF CUTTING ARAMID AND KEVLAR WITH A LASER

As aramid and Kevlar are extremely hard and elastic they can only be cut mechanically with great difficulty. Cutting aramids and Kevlar with a laser can win you over with some significant benefits:

  • No fraying: while the cut edges of fibrous materials usually fray when cut mechanically, the structural fibres are sealed by lasers. The result: clean, precise cuts without unwanted fraying.
  • No tool wear: as hard materials like aramids and Kevlar quickly blunt the blades of mechanical cutting tools, laser cutting has proven itself to be a more cost-effective method. A laser cutter doesn’t become worn, even by repeated use, as the laser process is contactless. This means lasers incur hardly any maintenance costs while the cutting quality remains consistently high.
  • Great precision: a laser cutter can produce narrow cutting joints of high precision and quality. Even the finest patterns can be produced accurately and at a high processing speed and level of quality. Even the finest patterns can be produced accurately and at a high processing speed. In addition, the precise technology makes it possible to process materials in every direction, regardless of the fabric structure.
  • Gentle process: the cutting process is contactless with the laser systems from JustLaser, meaning that the materials are not warped at all. As a result, you don’t need to spend a lot of time fixing things in place, and hardly any post-processing is necessary. As the process produces little dust, little cleaning is needed.
  • Maximum efficiency: with a JustLaser Laser Cutter, you can benefit from high processing speeds and ease of use. The lifetime costs are low in comparison to other technologies. You can also enjoy the benefits of this technology when cutting aramid and Kevlar with a laser.
