Cathay Composites - Satin Weave

Satin weaves allow formability around complex contours consequently this satin weave offers less stability than other weave forms. The most common satin weaves are four harness satin (4HS), five harness satin (5HS), and eight harness satin (8HS). The number indicates the total number of tows passed over then under. A 4HS weave consists of three tows passed over and then one passed under. For a 5HS, four tows are passed over, and then one under and 8HS is seven tows passed over and one under. The higher the satin weave number, the more formable and less stable it is.
