Low levels of carbon fiber can product interesting and aesthetically pleasing visual effects in articles made from thermoplastic resins.� The techniques used to incorporate carbon fiber into the thermoplastic resin can have a critical impact in the final appearance of the articles made from the resin.� One way to control incorporation of carbon fiber is to introduce it into the resin in an extrusion process as a pre-compounded masterbatch.
The pre-compounded carbon fiber masterbatches can be made using extrusion processes.� Since carbon fibers are susceptible to damage during extrusion, the form of the raw carbon fiber, as well as the process used to make the masterbatches, is important.� The form of the fibers used to make the masterbatch is critical to the consistent handling and feeding of the fiber into the masterbatch production process, and carbon fiber raw materials which have sizings that improve handling and consistent feeding are recommended.� � Carbon fibers are commercially available with various types and amounts of sizings, lengths, diameters, etc.� Selection of appropriate carbon fiber form is based on 1. feeding ability, 2. appearance in final product, and 3. physical properties of the final product.� In addition to carbon fiber form, the appropriate extruder location to feed the carbon fiber during the masterbatch production process must be selected.� We have found that downstream feeding during...
