Products of fiber reinforced plastic（FRP） are widely used in the industries of aerospace

chemistry and so on

but the online measurement and control of resin viscosity in fiber winding machine（FWM） is always a difficult problem to resolve in the production of FRP.A FWM resin viscosity control system is designed

in which Single-cylinder measurement solution and fuzzy control technology are applied

it is characterized by simple structure and easy programming and debugging.The value of viscosity and the parameter of fuzzy controller can be set through the friendly operation interface.The system greatly improves control effects.
