Description of Unidirectional Fabrics
Unidirectional woven roving is 0°or 90°unidirectional fabrics. Wefts or warps are bound with polyester yarn, hot-melt yarn and thin fiberglass yarn, and then they will be fixed by high temperature.
1. no binder used;
3.high strength in a specific direction;
4.increase the properties of laminated FRP in terms of ultimate tensile strength, delaminating resistance under stress and flexural strength;
5.reduce the weight of FRP;
6.make FRP surface smoother;
7.simplify the operation pf hand lay-up and improve productivity
Specification of Unidirectional Fabrics
Packing of Unidirectional Fabrics
The rolls should be wound on tubes with high tension. The individual roll can be wrapped in a plastic bag then protected by
carton box. Lay the rolls horizontally. The glass can be in bulk or paced on the pallets. The glass on pallets should be 3 rolls per
layer, 3 layers per pallets, protected against dirt by a plastic film, and reinforced with PET belts.
Application of Unidirectional Fabrics
This product has good dimensional stability and is mainly used in manufacturing pipes.
