  • the permeable transport web operates in combination with other transport components, such as binders, stitching fibers, adhesives, thermal bonding, various methods for entangling the staple fibers with the reinforcing fibers, diagonal reinforcing fibers (also referred to as transport fibers), and the like.
  • a proportion of fibers 46a are deflected from the plane of the layer 44 to become randomly oriented, intertwined and entangled with the reinforcing fibers 28, 32, 38, 42.
  • the staple fibers or cut fibers 46a effectively mechanically interconnect or attach the layers 30, 34, 36, 40 and 44.

  • the reinforcing layer 44 also maintains the relative position of the respective fibers 28, 32, 38, 42 in the reinforcing mat 18A.
  • the layer 44 provides strength and resistance to skew in substantially all directions. Additionally, while the layer 30 provides strength primarily in about the pull direction 29, the fibers 28 will resist skewing forces at some angles other than 0°. Similarly, the fibers 32 will resist skewing forces at some angles other than 90° and the fibers 38, 42 will resist skewing forces at angles other than +/-45°.

  • the contributions of the fibers 28 and 42 in combination with the reinforcing layer 44 provides the reinforcing mat 18 A with sufficient in-plane mechanical stability so that thin walled pultruded parts can be made with minimal skewing of the reinforcing mat 18 and minimal shifting of the relative position of fibers 28, 32, 38, 42.
  • in-plane mechanical stability refers to a resistance to deformation and skew in the plane of the article sufficient to use in a pultruded part having a non-planar profile.
