Major Applications include
Introduction
Several layers of unidirectional reinforcement material (yarn, strand, roving) are stacked and oriented by means of a weft insertion system in predetermined directions that can vary widely (0° to 90°). Additional stitching yarns applied by a knitting system bind the layers together to prevent slippage. Other reinforcing materials such as chopped strand mat and tissue can be added to the multiaxial structure.
Advantages
- Reinforcement in predetermined direction
- High drapeability
- Good filament wet out
- Good impact resistance
- Reduction of lay up time
Major Applications include
The multiaxial machine is used to produce multi-layer structures for reinforcement applications. Major applications for multiaxial products include composites for the boat and shipping industries and rotor blades for power stations.
Manufacture of different types of multiaxial non-crimp fabrics composed of glass, carbon or synthetic fibers as well as hybrids of different materials,which can be used as reinforcements in road engineering ,composite materials making,etc.
Knitted glass fiber scrim fabrics
Description
- In the knitting process, machine direction and cross direction yarns are stitched together using a third yarn, creating a strong, dimensionally stable mechanical bond.
- Knit goods are planar or tubular structures made by the inter-looping of loops of yarns connected by a knitting system in the length direction (warp knitting) or width direction (weft knitting).
- The warp-knitting machine is fed with section beams and each end passes through a needle. Knitting elements form loops and bind the warp yarns together.
- For production of knit scrim, a feeder device inserts crosswise glass weft yarn. Additional synthetic warp yarns, pulled from a beam, combine the warp and weft glass yarns together to shape the desired structure.
- The weft-knitting machine is fed directly by a determined number of yarns. The loop forming device uses latch needles to create products with high flexibility.
- Glass yarns can also be processed on conventional weft knitting machines. In this case, due to high bending strains, the use of plied yarns and fine filaments is required.
Applications
- Asphalt reinforcement
- Concrete reinforcement
- Modified bitumen roofing
- Drywall tape
- Elasting casting tape for plaster reinforcement quired.
