The materials to be cut may be in the form of RAW fabrics  or <a href=\"https:\/\/www.nitprocomposites.com\/carbon-fiber-pultruded-tubes\" target=\"_blank\"><strong>pultruded carbon  fiber tubes<\/strong><\/a><strong>, <\/strong>as prepreg tubes, sheets or plates.<\/p>\n<p>  The implications of cutting will relate with the type of, or condition of the  material being cut and various are the factors which we shall cover in this  blog<\/p>\n<p><strong>Issues  with Cutting Carbon Fiber<\/strong>: <\/p>\n<p>  Before  we move on to the cutting devices let us look at the issues particularly  related to the behavior of carbon fibers: <\/p>\n<ul>\n  <li><strong>Fiber flatness: <\/strong>The fiber tends to be wavy at times and this may affect accuracy  of cutting shapes <\/li>\n  <li><strong>Dust<\/strong>: when cutting the fiber, dust will fly which may fall on the  cutting surfaces and pollute the environment besides posing danger to the  operator <\/li>\n  <li><strong>Marking<\/strong>: because of the dark color, (generally black) of carbon fibers,  marking of particular shape to be cut can be challenging. Pencils may not work  for proper marking and one needs to use specific tools <\/li>\n  <li><strong>Resin<\/strong>: the resin embedded in the composite may evaporate into toxic  fumes which could pose danger to the operator<\/li>\n<\/ul>\n<h2><strong>Cutting  devices<\/strong><\/h2>\n<p>  The  available cutting devices can be classified into the following main types:  Manual or Automatic devices. <\/p>\n<p>  Whereas  the manual devices can be used to cut most forms of materials to be cut,  including pultruded pipes or structural members, the automatic machines are  generally used for cutting flat fibers or fabrics or sheets.<\/p>\n<p>  When  using manual devices, it is advisable to use a table with an inbuilt down-draft  vacuum system, and\/or with dedicated fume extractors.<\/p>\n<h3><strong><u>Manual Devices<\/u><\/strong><strong>: <\/strong><\/h3>\n<ul>\n  <li><strong>Rotary manual cutters<\/strong>: Hand tools could be a simple as angle grinders using  tungsten carbide disc or a serrated, sawed disk.  They may come with a fixed speed, or variable.  These devices are generally used for fast cutting of straight lines as it may  be difficult to maneuver them around curved profiles.  The serrated or saw type disc may pose some  challenge with resins if embedded in the material being cut as the resin material  make clog the spaces between teeth. <\/li>\n  <li><strong>Jigsaws<\/strong>: Jigsaws are handy tools that use relatively thin blades and are  easier to maneuvers over covered profiles<\/li>\n  <li><strong>Flexible trammels: <\/strong>Flexible trimmers are another type of useful handy tools  that are slim and come with flexible shaft powered from a remote motor. They are  relatively easier to move around curved profiles. Trammels can come with  tungsten carbide discs or ceramic discs depending on applications <\/li>\n  <li><strong>Hacksaws<\/strong>: hacksaws are the simplest manual cutting tools that can only be  used on an over hanging portion of a molded carbon fiber material as they have  limited possibility to penetrate a flat surface on a table and their blade can  wear out very fast needing frequent changes. <\/li>\n<\/ul>\n\n\n<h3><strong><u>Automatic Devices<\/u><\/strong><strong>: <\/strong><\/h3>\n <ul>\n  <li><strong>CNC Router<\/strong>: A CNC router is a universal tool used for many applications of  material removal. It is a flat bed, computer controlled machine wherein, a thin  sharp edged tool (blade) is made to move on a predefined path according to the  profiles to be cut. A router generally is used to cut fabrics in single ply. It  will have a soft top surface to allow penetration of the free end of the blade <\/li>\n  <li><strong>CNC Knife Cutting Machines<\/strong>: CNC cutting machines use reciprocating  knife technology and are similar to the router but are generally better known  as CAD CAM systems. These machines come with a flat bed which may be either  fixed or conveyorized. <\/li>\n<\/ul>\n<div class=\"imagebox\"><img decoding=\"async\" src=\"https:\/\/www.nitprocomposites.com\/assets\/images\/blog\/how-to-cut-carbon-fiber-1.jpg\" alt=\"How to cut Carbon fiber?\" loading=\"lazy\"><\/div>\n<p>A choice of knives\/blades maybe  available to cut different kind of materials. Like the router, these machines  are operated form an inbuilt personal computer wherein, files can be accessed  of profiles to be cut. <a href=\"https:\/\/www.nitprocomposites.com\/carbon-fiber-cnc-parts\"><strong>CNC cutting  machines<\/strong><\/a> can be used for cutting carbon fabrics in multiply as they are  provided with bristle blocks which allow the penetration of the free end of the  knife below the material to be cut, thus offering good quality cut in the most  intricate of shapes.<\/p>\n<p>When you want to cut several  pieces of material from the given fabric or molded material, a CNC cutting  machine has the possibility of achieving the highest optimization of usage of  raw material, thus minimizing wastage as the profiles of individual pieces can  be suitably laid on a predefined marker across the width of the fabric to be  cut. Such an activity actually provides more advanced information about the  total amount of raw material required to cut the lot.<\/p>\n<h2><strong>Conclusion<\/strong>: <\/h2>\n<p>  An  experienced operator will choose the most suitable of the cutting tools or  devices based on various factors which can be summarized as follows:<\/p>\n<ul>\n  <li>Nature of shapes to be cut<\/li>\n  <li>Nature of material to be cut<\/li>\n  <li>Cost of materials, and the need to economize<\/li>\n  <li>Available type and size of raw material to be cut<\/li>\n  <li>Speed of cutting<\/li>\n  <li>Accuracy Levels<\/li>\n<\/ul>\n\n<\/body>","protected":false},"excerpt":{"rendered":"<p>Owing to their exceptional physical properties, carbon fibers are nowadays an important raw material used in the composite, and carbon fiber products industry and find wide application in the aerospace, automotive, wind energy, body protection industry, as well as in other emerging fields.
