Porous nylon PA56 peel ply. A100PS ECO is white with red tracer. Recommended for composite manufacture and metal bonding applications up to 400°F (204°C).
Peel ply is a fabric layer used in the manufacture of fiber-reinforced plastics, or composites, for a variety of purposes
- Protection
- Surface preparation
- Adhesion
- Resin management
- Surface finish
- Void elimination
When choosing a peel ply, it's important to consider the tightness of the weave and the weight of the material, as these can affect the performance and appearance of the final composite part.
Peel ply can protect a composite surface from damage during transport and storage. It can be removed after curing to leave a textured surface that's ready for bonding or painting. Peel ply can also improve the adhesion of adhesives, paints, or subsequent layers and can help prevent excess resin from accumulating, which can reduce the weight of the final part. Peel ply can create a smooth, consistent surface finish while allowing excess air and resin to flow through, which can eliminate voids in parts.
Peel ply material is used in several different composite manufacturing processes. For example, the use of peel ply in vacuum bagging of prepreg or wet-preg and vacuum infusion processing are common applications. It is also used in other processes such as glass lamination and compression molding. For vacuum bag cure of prepreg or wet-preg, peel ply is placed against the final prepreg layer. Afterwards, it is covered with a release film and breather material. When used on composites, peel ply, release film, and breather helps to remove gases and excess resin from the laminate.
For vacuum infusion of composites, peel ply is placed against the last layer of dry fiber reinforcement. It can be covered with a flow media, such as Infuply2 or VI10. In addition to leaving a nice texture for subsequent processing, the peel ply allows for easy removal of flow media and other process materials after the part is cured. Products are available with black or red pinstripes for easy identification on a cured composite part. It can also be left in place on the cured part to keep it clean of contaminants prior to subsequent processing.
