Wound composites products 1/2
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.
