Its width and length suit projects that need continuous sheets rather than many small pieces, and its ability to conform to curves helps on marine and molded parts.\u003c\/p\u003e\u003cp\u003eIt is less appropriate for structural applications that require woven directional fibers or much higher weight fabrics; users who need a strong directional laminate should look for woven roving or biaxial cloth instead.
