Multiaxial

Several layers of unidirectional reinforcement material (yarn, strand, roving) are stacked collectively and oriented by means of a weft insertion system in predetermined directions that can vary within large limits (0° to 90°). Additional stitching yarns applied by a knitting system bind the layers together to prevent slippage.

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.

Vetrotex glass yarn multiaxial application

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
