ARMATON multiaxial fabrics
-
ARMATON multiaxial fabric is a textile material consisting of one or more layers of glass fibers. The layers are oriented in various directions and stitched with a polyester yarn.
ARMATON multiaxial fabrics are manufactured using state-of-the-art equipment from Germany, which guarantees output of high-quality products.
- Maximum width of sheeting is 1.27 m
- 10 cm bands and wider are possible
- Strands are normally oriented in 0, 90, +45, -45 directions. Change in orientation angle from +20 to +90 and from -20 to -90 is possible
- Plying with a nonwowen fabric or chopped fiber for better adhesion inside composite or for finishing of surface are possible
- Depending on type and length of a stitch of stitching yarn, manufacture of fabric with various extent of drapability is possible
- System of sizing agents is meant for achieving excellent adhesion with polyester, epoxy and phenol resins (a general-purpose sizing agent, silane, is use
- The fabric can be manufactured out of various types of glass and basalt or combination thereof.

Typical application:
ARMATON multiaxial fabrics are used as a reinforcing filler for making high-endurance materials out of fiberglass reinforced plastics (FRP).
The FRP based on multiaxial fabrics are successfully applied in the following industries:
- wind energy (blades, aerodynamic tunnel of wind power generators)
- aircraft (fuselages of planes and helicopters, main and anti-torque rotors of helicopters, wings, aerodynamic fairing, passenger seats)
- space (aerials, paraboloidal mirrors, autoclaves)
- marine (hulls)
- automotive (non-load bearing parts of a car body, refrigerated containers)
- railway (bodies of rail and subway cars, aerodynamic fairings, load-bearing parts of interior furnishing)
- building (reinforcement of concrete structures, window and door profiles, tents, bridges)
- tubes and vessels for storage and transportation of deleterious substances
- sports gear (tennis rackets, skis, surfs boards and snowboards, boats, bicycle frames, ice hockey sticks and helmets)
- medicine (medical devices)

Advantages:
glass-fiber multiaxial fabrics are non-inflammable, non-toxic.
Compared to woven roving glass fabrics, multiaxial fabrics ensure:
- high strength properties in terms of tension, bend, torsion
- impact resistance
- quick and high-quality impregnation with binding agent
- reduction in quantity of fabric during laying and optimization of composites manufacturing process
- high workability
- possible reinforcement of composite materials in different directions
- reduction in consumption of resin to 20-30%: owing to non-interwowen yarns, strands are laid denser as compared to roving fabrics, thus resulting in lower resistance to flow of a binding agent
- final weight may be reduced to 50%
- mechanical strength may be increased twice (twice mechanical strength of roving fabrics with comparable surface weight)
- strict adherence to assigned reinforcement design
- absence of nodes on surface of product.
