Filament winding is a technique for manufacturing reinforced plastic parts of high strength and low weight in which continuous fibers or filaments encased in a matrix of resinous material are wound into a definite pattern.

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.

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.

Glass reinforcements usually used by "Eurokompozit" are: roving, yarns or unidirectional woven tape and epoxy resins.

With optimal roving position, proportion, fibre selection and suitable resin we obtain:

  • high mechanical properties
  • pressure resistance (inner and outer)
  • big torsion stability
  • temperature stability
  • high electric and thermal resistance    
  • small thermal expansion coefficient
  • corrosion resistance
  • low specific density
  • electric conductivity
  • good sound isolation

 

Methods of winding: hoop, helical or longitudinal give wide spectrum of different mechanical properties and possibilities of meeting the required properties. Filament wound tubes and cylinders are custom-made, with dimensions from Ø8 to Ø1100 mm, and length according to customer requirements.

Maximum weight for winding (tools + tubes) is 1000 kg.
