Coating Viscosity Measurement Improves Molding Compound Process
Boston—Cambridge Viscosity’s advanced sensor technology is helping
Cytec Engineered Materials streamline production of composite materials used in aerospace, high-performance industrial and
other extreme-demand environments.
Cytec supplies composite materials such as prepregs and molding compounds to companies that mold parts. The ratio of resin-to-fiber is very important, with different applications requiring different ratios. Cambridge’s
ViscoPro 2000 viscometers are used to control the viscosity of a resin solution that binds the carbon fiber. Strings of carbon fiber are run through a resin bath where they are coated, and the resin acts as a binder for the carbon fiber so that it can be molded into a part.
“The implementation of the viscometer system has enabled us to continually monitor and control the resin, which allows us to greatly reduce variation within the product,” says Cytec Engineer Troy Farry. Prior to using the viscometers, technicians were required to take measurements at certain intervals in order to determine if adjustments to the resin characteristics were necessary.
This method created a delay in reaction time, resulting in a great deal of variation that made it harder to remain within customer requirements. According to Farry, “not only have the viscometers allowed for a more consistent product, they have reduced the error and scrap rate of our material. By streamlining the process, our technicians can now focus on other areas of development, instead of having to manually monitor the process.”
