Description

Release ply fabrics are peel plies, used to texture the surface of a composite laminate. The peel ply surface is helpful for secondary bonding or painting of the composite laminate. Release ply fabrics may reduce or eliminate the need for sanding or abrading. These fabrics are scoured, and heat set to remove contaminates and reduce shrinkage.

Release Ply G is a tight woven polyester with excellent strength. Stitch Ply G is a similar version of Release Ply G with black tracers (pin stripes) for easy identification on the laminate.

Benefits

• Strength of tighter weave aids removal after cure in most demanding applications.

• Polyester fiber provides additional strength and resistance to aggressive resins such as phenolics.

• Peel plies strip off of cured laminates leaving a fine textured surface, reducing time spent hand finishing.

• Black pin stripes make fabric more visible to reduce risk of leaving in place during bonding process.
