FRP/GRP Pipe Filament Winding Machine Working Process
FRP/GRP Pipe Filament winding is perhaps the most succinct and clearly named of all the machine processes. It is traditionally used to produce cylindrical and spherical products, e.g., chemical and fuel storage tanks and pipe, pressure vessels and rocket motor cases. The advent of computer-controlled winding machines has expanded the shaping capability, making it useful for products such as airframes, helmets, driveshafts.
Continuous, resin-impregnated fibers or roving are wound on a rotating mandrel in a predetermined pattern, providing maximum control over fiber placement and uniformity of structure. In the wet method, the fiber picks up the low-viscosity resin either by passing through a trough or from a metered application system. In the dry method, the reinforcement is impregnated with resin prior to winding.
The integral fittings and vessel closings can be wound into the structure. When sufficient layers have been applied, the composite is cured on the mandrel and the mandrel is removed.
Formulations can be tailored for the chemistry held by the tank. We encourage collaboration with you to understand your specific tank application for accurate quoting of the resin chemistry.
