The Essentials for Applying Sizing to Carbon Fibers

Posted by Maureen Redmond on Jul 20, 2020 10:29:26 AM

With the increasing variety of resin systems available for carbon fiber and other high-performance fibers, there is a growing need for development of sizing materials which interface well with each resin/fiber combination.

For the development of the sizing material, it is often difficult to experiment without obtaining un-sized fiber. Unless you produce the fiber in your own facility, in many cases it would be necessary to de-size the fiber first, and then apply the desired sizing materials.


Any handling process can damage the fibers, and de-sizing / re-sizing can be particularly abrasive to the fiber. Thus, equipment for this process needs to put this factor into consideration, and must be as gentle or even more gentle to the fiber as the in-line sizing process during the production of the fiber.

We can provide turn-key systems for single tow sizing development lines as well as multi-tow sizing lines for production scale output requirements. Single tow lines are scalable and configurable: in many cases they are compact table-top units. Production scale lines incorporate industrial-grade equipment, same as the equipment we provide for fiber production plants.

See below for some considerations for specifying the right equipment for the sizing line you may need.

Got ISO 9001 Equipment Calibration Requirements?

If speed and length calibration and verification with NIST traceability are a vital part of your ISO program, you need the proper test equipment to validate and maintain the accuracy of your production and process monitoring equipment.

 

A Portable Measuring Solution

At Izumi International, we produce feed rollers, nip rollers, pinch rollers, stretch rollers and driven winding systems designed to maintain a constant driving speed on fibers or web materials.  To calibrate our equipment, we built a portable calibration tool to quickly and accurately measure product length and the line/surface speed of rollers, webs, belts and product.  We realized this tool would also benefit our customers Quality and Maintenance groups that need to validate machine Line Speed/ Length displays or to troubleshoot and maintain their equipment. 

The PLSC-1000 portable counter provides a NIST traceable speed/length calibration system designed to be easily moved around and mounted to production equipment for test, calibration and verification of speeds and lengths shown on the production equipment displays.
