FILAMENT WINDING

Filament winding is a versatile process for producing composite sections in a hollow or tubular form, by winding resin impregnated fibres onto a rotating mandrel.? The physical properties of the tube can be controlled by altering the types of resin and reinforcement and by varying the angle at which the fibres are wound onto the mandrel.? This process can be carried out under computer control and, if required, the final component can be made with a combination of different wind angles.
Fibre Reinforcement
Glass, when drawn into fine fibres of 10-15 micron diameter, has a very high tensile strength - up to 4000 MPa, or about ten times that of steel.? However, to make a usable material, the glass fibres have to be bonded together with synthetic resins.? Other fibres such as carbon, aramid (e.g. Kevlar), polyester, cotton and asbestos can be used, where their special properties are sought.

Resins
Thermosetting resins are used in the manufacture of Filament Wound tubes.? Epoxy resin is used for the majority of TIANZE Filament Wound Tubes but polyester,? vinyl-ester and acrylic (Modar)? resins are also used, with glass or other fibres.? Special resins can be formulated for particular high temperature, electrical performance or chemical resistance requirements.?

Composite tubes

The properties of Filament Wound composites depend not only on the characteristics of the materials used but also on the position and direction of the fibres in the component.? Fibre reinforced composites have much greater strength in the direction of the fibres, than at right angles to them.? For example, tubes in the TIANZE cylinder range are wound at a shallow helix angle of about 15o, to give good hoop strength and therefore a higher bursting strength.?? Physical properties, such as strength and elastic modulus, are quoted both in the hoop direction and axially.?

The use of a reinforcement made from polyester yarn, instead of glass,? results in a material with good bearing characteristics.? Similarly, other combinations of reinforcement and resin produce materials for electrical? insulation,? materials for pump bodies, structurally strong types for aerial masts, and so on.?

Size Range

TIANZE Filament Wound composite tubes can be produced in a wide range of sizes, with internal diameters from 25mm up to 500mm (1" to 20").? They are available in lengths up to 3 metres approx. (10 ft.), subject to availability of tooling.

Filament wound tubes have exceptional inter-laminar shear strength and can be machined to very close tolerances.?
Tubes weighing half as much and with equal strengths as similar size aluminum tubes may have 33% thinner wall thickness.?
Glass/epoxy resin ratios, winding tensions, and pre-determined winding angles provide exceptional directional strength properties.?
Various epoxy resin formulations are available with 135°C, 155°C, 180°C, 200°C and cryogenic continuous use ratings.?
Tubes can be made with ID’s as small as .187” and as large as 48” Dia. Standard lengths are 48”, 90” and 96”, depending on the ID size and some sizes can be made in longer lengths.
Common Applications for Machined Filament Wound Tubes:
Antennas,Impeder Tubes,Switch Insulation,Waste Water Treatment,Cylinder Tubes,Bearings,Fuse Tubes,Cryogenic Pipe,Bushing Liners,Battery Casings,Cryogenic Neck Tubes,Frac Plug Components,Propellant Tube,Munition Bodies,Launch tubes,
Glass/epoxy filament wound tubes offer excellent resistance to weather, ultraviolet radiation, temperature extremes and moisture.?
Composites made from glass/epoxy are also excellent electrical insulators, are nonmagnetic and will not interfere with radar or radio frequency signals.?
Lamitex glass/epoxy filament wound tube composites, with few exceptions are more resistant to chemical corrosion than stainless steel, monel and titanium.
