Glass fiber plaid is a non-twisted roving plain fabric, which is an important base material for hand lay-up glass fiber reinforced plastics. The strength of checkered cloth is mainly in the warp and weft direction of the fabric. For occasions requiring high warp or weft strength, it can also be woven into unidirectional cloth. It can arrange more untwisted roving, single warp fabric and single weft fabric in the warp or weft direction.
