Auxiliary Materials
Peel ply
A sacrificial porous fabric placed against the laminate. When removed, it leaves a controlled textured surface for later bonding or coating.
In simple terms
A sacrificial porous fabric placed against the laminate. When removed, it leaves a controlled textured surface for later bonding or coating.
Best for
Secondary bonding, adhesive preparation, protection of uncured surfaces and controlled resin bleed stacks.
Watch out for
Peel ply is not a universal release layer. Its weave, finish, cleanliness and removal timing affect the resulting bond surface.
Typical applications
Bonded joints, repair scarves, prepreg and wet-lay-up surfaces.
