Why are the edges of Fiberglass tape woven to prevent fraying?

1. Physical Sealing:

The fiber bundles are tightly bound together on both sides of the Fiberglass tape using a warp and weft interlacing or sealing process, forming a "sealed edge" structure. This prevents the fiber ends from sliding freely, thus preventing burrs during cutting or stretching.

2. Resin Sealing:

A layer of resin is coated onto the edges of the striped tape and cured to form a hard seal, which both secures the fiber ends and improves abrasion resistance.

3. Edge Pressing Reinforcement:

Hot pressing or mechanical pressing is used to make the edge fibers tight and flat, further improving tear and tensile strength.

4. Improved Performance:

After preventing fraying, the tape remains clean during application, cutting, and bonding, avoiding fiber residue contamination of the substrate and extending its service life.
