Peel Ply

Aerovac Composites One Peel Ply

Aerovac Peel Ply Meets a Wide Variety of Composites Manufacturing Needs

Peel ply products by Aerovac are available in multiple materials and formats to offer flexibility in options and to match specific application requirements. Our woven fabrics range from light to heavyweight and are available in both nylon and polyester. Some offer adhesive backing which helps simplify the application process while release coated peel plies make removal much easier. Choose from standard formats, slit width, or cut-to-shape formats. Coarse and fine weaves are also available.

Product Benefits

Peel ply creates a textured surface on the composite, improving adhesion of subsequent layers, adhesives, or paints. Additionally, it can also help prevent excess resin accumulation, reducing the final part weight. When selecting a peel ply it is important to consider the tightness of the weave and the weight of the material because both will affect the final appearance and performance of the composite part. The right selection can help create a more consistent surface finish, and as a result, a more attractive product.

Using Peel Ply

Peel ply is used in several different composite manufacturing processes. It is most commonly used in vacuum bag cure of prepreg or wet-preg and vacuum infusion processing. 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. The combination of peel ply, release film, and breather helps to remove gases and excess resin from the laminate.

For vacuum infusion, 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.
