Peels away to leave a uniformly textured surface free of surface film for subsequent bonding and secondary laminating. Apply as the final layer directly onto the laminate. After curing, remove completely before further processing.

This peel ply is a washed, heat-treated plain-weave fabric made from polyamide 6.6 (nylon). It provides temporary protection for the laminate surface and is removed before bonding or applying additional laminate plies. It is not a reinforcement layer intended to remain in the finished component.

Features and benefits
Cleaning after weaving removes most residual sizing. The peel ply protects the covered laminate surface from contamination until further processing. The red tracer yarns make it easier to visually identify any remaining peel ply after removal.
The surface texture left after removal can reduce subsequent sanding work. The surface preparation requirements of the selected resin and adhesive systems must still be followed.
Applications
- Preparation of bonding surfaces and areas for secondary laminating on composite components, for example in composite tooling, boatbuilding and carbon- or glass-fibre composite repairs.
- Temporary protection of the laminate surface during storage and transport prior to further processing.
- Peel ply layer directly on the laminate in hand lay-up and suitable vacuum bagging and resin infusion lay-ups.
Compatible resin systems
Suitable for epoxy, vinyl ester and polyester resins.
Processing
Hand lay-up: Apply the peel ply as the final layer onto the wet laminate, wet it out evenly with resin and smooth it into contact. Avoid trapped air and wrinkles in areas intended for subsequent bonding.
Vacuum-assisted processes: The peel ply is placed directly on the uppermost reinforcement ply. Additional consumables, such as perforated release film, bleeder fabric or infusion flow media, are positioned above it as required by the chosen process. For resin infusion, the peel ply is positioned as part of the dry lay-up and wetted out with resin during the process.
After curing: The peel ply can remain on the component until further processing is required. Before bonding or applying additional laminate plies, remove it completely and inspect the surface for remaining peel ply and contamination.
Bonding considerations: A textured surface alone does not replace verification of the complete bonded joint. Follow the processing instructions provided by the resin and adhesive manufacturers and, for demanding applications, verify suitability using a representative test assembly.
Storage and cleanliness
General storage recommendation: Keep unused peel ply clean and dry, preferably in its sealed original packaging. Protect it from dust, oil, grease and other contaminants to prevent their transfer to the surface intended for bonding.
