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.

Glass fiber cloth draws glass into very fine glass fiber, which has good flexibility at this time. The glass fiber can be spun into yarn and then woven into glass fiber cloth by weaving machine. Due to the extremely fine glass fiber and the large positive surface per unit mass, the temperature resistance has decreased. Just like a candle can melt a thin copper wire.
