Multiaxial Banner


Description of the process

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 of such a structure include:

  • 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.
