Weave Styles & Benefits
| property | value |
|---|---|
| Plain Weave | Balanced strength, good stability, low crimp, easy handling |
| Twill Weave | Better drapeability, moderate strength, smoother surface |
| Satin Weave | Excellent drape, high coverage, complex contours |
| Unidirectional | Maximum strength in one direction, ideal for load-bearing |
| Multiaxial | Engineered for complex structural loads (±45°, 0/90°), used in wind, marine, aerospace |

Quality Control
All batches of fiberglass fabric are rigorously tested:
- Area weight and weave uniformity
- Yarn tension and warp/weft ratio
- Sizing compatibility with customer resin system
- Dimensional stability and shrinkage under cure
- Flame resistance and dielectric breakdown voltage (if required)
Customized weights, widths, weave types, and resin-compatible sizings are available on request. Contact our technical team for laminate design, sample supply, and performance testing support.
